1 vacation!), many of these mags list#
1 v1.34 7.3.96: Fixed a bug in the copy to+D routine, which caused code files tocrash on +D/DiSCIPLE, fixed the Hook Codeexit carry, corrected a (minor) bug in theload/save syntax scan code. Code length is5960 bytes (unpacked).
1 v1.331 6.3.96 (intern) Fixed a couple ofbugs in the CAT routine, non Spectrumfiles no longer crash (thanks to JohnCleveland for pointing this out). 128Ksnapshots now have their number of sectorsprinted out correctly. Code length is now5955 bytes (unpacked).
1 v1.33 21.2.96 (intern): Made Command Codesreturn to BASIC without a crash. Fixed the"bug" in the CAT code which caused FPnumbers to be inserted twice - this wasn'tmy fault - the +3 CAT code inserted them -God knows why, the command quite blatantlyfails syntax!!! Code length is now 5949bytes.
1 v1.32 20.2.96 (intern): Added a lot moreCommand Codes (See, got the right namethis time!!!), and put details of them inthe COMMAND.DOC file.
1 v1.31 18.2.96 (intern): When copyingto/from +3 drives, the filenames aredisplayed (ala +3 DOS). Upgraded7 moreprogram (v1.1) - see separate docs. Codelength is now 5728 bytes.
1 v1.3 17.2.96 (intern): Added (conditional)support for Hook Codes - I hope +Dprogrammers will hear abt these conditionsand support them, I can say confidentlythat 100% of current programs won't workwith these HCs..but...WTF. Jiggled memoryconfiguration around, so have more memoryto play with. Corrected the CAT display -now gives the drive number, and the CAT !syntax no longer clears the screen.Corrected a major bug which only becomesevident during run time - if a drivenumber was specified (instead of *) thenthe command was accepted when input, butkicked up an error when running -apologies to everyone who thought theywere going mad! Code length is now 5556bytes.
1 v1.125 16.2.96: Added syntax checking to obtain an abbreviated catalogue, ie CAT 1!syntax. Fixed the more viewer to avoidcrashes (for more details see the moredocumentation). Code length is now 5376bytes.
1 v1.121 15.2.96 (intern): Bug fix release.Made the handling of variable filenamesthe same as with +D ie following the driveindicator with a semi colon before thefilename. Fixed a minor bug in the copyroutine which caused +3 drive onlydestinations to report bad filename.Actual code length is now 5278 bytes.
1 v1.12 13.2.96: Added the FORMAT command,corrected the LOAD @ syntax to workproperly (again...). Code length is nowabout 5230ish bytes.
1 v1.11 12.2.96 (intern): Fixed a lot ofbugs, allowed a 4th parameter to go withthe LOAD @ syntax so now a LOAD@drive,track,sector,add is possible. Writeprotect files are now write protected - norename/erase is now possible (thanks to arather bizarre discussion on c.s.s formaking me aware of this). Made the POKE @syntax work. Optimized the code a little -length is now 5079 bytes. And wrote thesnazzy MORE style file viewer.

1 Without spending too much time thinkingabout it, pick a random number between 10and 99. I bet the two digits in yournumber were different! If there was anequal chance of each number being picked,there would be a probability of just over12% that one with two identical digits waschosen. However, when asked to pick a"random" number, people generally try tochoose an "insignificant one": one withunrelated digits, not too close to eitherend of the range.

Pin 20 of the IC holder you areabout to solder on to IC 8 (if that is theoption you have chosen) should be removed.Remember, the 128 ROM sits atop IC 8 andthe pins of the ROM, or the IC holder, aresoldered to the pin shoulders of IC 8, pin1 to pin 1, and so on.
1 Whenever you do an interrupt routine itis essential that the contents of all theregisters are exactly the same after youhave finished the routine as when youstated it. The only way to ensure this isto push the contents of all the registersonto the stack at the beginning of theprogram, and pop them all of again at theend. The contents of BC, DE, HL and IX areall pushed onto the stack. But thecontents of AF are pushed on first becausethe accumulator and the flag register areused to test whether a program is beingRUN. If no BASIC program is being RUNthere is no point in doing a trace.
1 When you've typed in this code, a bootwill appear at the bottom of the screen.You can now hold down combinations of keys6,5,4,3,2,1 to visit each screen. Thefinal screen can be accessed and, to behonest, is quite easy. Then again, it'sall down to a matter of timing!
1 When you run the trace, keep a copy ofthe BASIC program you are checking near athand. You will want to check off each lineas it is executed to see how the programis structured. At points where it runsinto difficulty, step through the programslowly statement by statement, pausingbetween each by pressing the BREAK/SPACEand SYMBOL SHIFT keys together.
1 When you press 3, the program will ask youfor a start address once more. This shouldbe the start address of the machine coderoutine you've just fed in, though you cansave any part of the memory by using adifferent start address.
1 When you enter the world of machine codeprogramming you are approaching your homecomputer on its most fundamental level. Not only do you have to understandsomething about the hexadecimal nimbersyou key in, and the binary numbers thecomputer converts them into, you also haveto understand how the computer itselfworks.
1 When you enter the wonderful world ofmachine code programming you run into anumber of strange paradoxes. Althoughmachine code is the language themicroprocessor itself uses, you cannotfeed it directly into your spectrum. Itmust be entered by another program - whichon a spectrum means using BASIC. Nor canyou simply run a machine code programusing a machine code command, you have tocall it out of a BASIC program or by usinga BASIC instruction.
1 When tou RUN the program, it will displaya menu. This asks you whether you want to'Enter machine code','Examine memory' or'Save bytes to tape/disk'.
1 When this happens, it's our duty to goaround informing all the relevant groupsabout the information. Although we are inregular personal contact with them all,repeating the information can become timeconsuming and tiring.
1 When they had safely got back into thecraft, the man was taken directly to themedical room and placed on the table readyfor the samples to be taken.
1 When they were all in thier suits heopened the airlock and stepped outsideclosely followed by the others, the groundfelt soft underfoot and was covered with awhite powdery substance, Coria bent downand scooped a handful up, 'It's water!'she said as it started melting in herhand. Aleen laughed to see the puzzledlook on her face 'It's frozen water, ourancestors called it "Snow", the lastrecorded snowfall on this part of theplanet was in the year 2573, a few hundredyears before our ancestors started thejourney to find a new world'.
1 When the statement number has been pokedonto the screen the processor returns tothe main program again to execute a smallroutine which make the digits appear whiteon a small black panel. It does not matterthat this is done after the numbersthemselves have been printed.
1 When the routine is saved, the menu comesup again.3
1 When the first colonies of humans came tohis planet they were not the generationthat had left mother earth, it was thiergreat grandparents who built the craftsand started the journey to seek outanother planet for them to live on.
1 When the carry flag is set, the jump ismade, another 1000 is subtracted, thecounter is incremented and the wholeprocess repeats until the contents of theHL are less than 1000 and the additiondoes not set the carry flag.
1 When no keys are pressed, the processorwill move straight on to 'pop ix','pop hl''pop de','pop bc' and 'pop af' whichrestore the registers to thier values atthe beginning of the interrupt by pullingthe stored values one after the other backoff the stack.
1 When a key is not pressed, the value itgives is 1. When it is being pressed, itsvalue changes to 0. To stop the trace, twokeys have to be pressed simultaneously,the SYMBOL SHIFT and the BREAK/SPACE. Thishas been done so that the keyboard can beused normally to edit the program whilethe trace is on.
1 When a BASIC program will not RUN, yourcomputer will often give an error messagewhich tells you which line it cannotexecute. This may be all you need to knowto debug a short, simple program. But whenyour prorams get longer and morecomplicated, such a message may stillleave you in the dark.
1 When a particular function is requiredseparately you must remember to canceleach unwanted function. Having selectedthe function/s required, follow theon-screen instructions to return to BASIC.You can now use the usual LPRINT "

1 When you switch on your spectrum itautomatically goes into BASIC. So you mustuse a BASIC program to POKE in yourmachine code program and a BASIC commandto run it.

1 When you have finished entering thecorrection, press ENTER, then examine thememory again to make sure that you've gotit right this time.
1 When I loaded the snap, I was throwstraight in the middle of the game, withno idea what was going on, or what thekeys were.
1 What you can reclaim off a chewn-up tapeprobably wouldn't merit all the effort putin to recovering it, because a tapechew-up normally damages several feet ofthe tape and you are looking at the lossof many bytes - but there again, it allboils down to what you have to work with.If, say, the area of damage was confinedto two identical files on opposite sidesof the tape, and the damaged portions didnot overlap the same bytes of these files,you can reasonably expect to rebuild a newand complete file from the two defunctblocks.

1 Very few people would think of 99 first,unless they were deliberately trying tospoil the experiment! However, a trulyrandom number would be just as likely tobe 99 as 10, 11, 12, 13 or any other.Since, in our universe, a variable mayonly take one value, and all events whichtake place must depend on one variable ormore, I would contend that all events arepredetermined and that the future could bepredicted exactly if we only knew the keyto the sequence involved.

1 To read ON-LINE, which is updated daily,it's on page 650 on Teletext, Channel 4.R
1 To print out a character on the screen youfirst have to locate it in the characterset. And as each character is made up ofeight bytes, you have to count the ASCIIvalue times eight along from the beginningto find the character you want.

If it is a 128K Speccy thespeed of the videochip (or ULA) is testetto distinguish the "normal" 128K Speccies(128, +2) from the Amstrad Speccies (+2A,+3). This is possible as the rebuildAmstrad ULA is a bit slower when the TVPicture is built up. Even a +2A/+3 with aFixer Kit (normal 128K ROM) will bedetected as a +2A/+3.

1 This way you will be able to see clearlythe structure of the program. You'll beable to spot if the computer is RETURNingfrom subroutines properly. You'll also beable to work out the value of thevariables as you go, and check thatconditional IF...THEN statements are beingfulfilled and that GOTOs go to the rightline.

1 This trace program simply PRINTs out onthe screen the number of each line and thenumber of the statement in that line as itis executed. To make full use of the traceyou should have a copy of the programhandy. Then follow the program through tothe place where it stops, using the trace.

Basically,any numbers the Speccy picks are generatedby sequences which, though long andcomplex, repeat after a fixed number ofiterations: 65536, in fact. This numbermay seem a bit strange but, because it's apower of two, its binary representationcontains only the digit one (which keepsthe computer happy!).

The information they contain isfixed permanently when the ROM chips aremanufactured and they are protectedagainst tampering. No matter what you doto your computer - short of physicaldamage - the ROM will restore itsfunctions to working order if you switchit off and then back on again.

I don't expect anyonewould write to them, pleading not to closedown. At present, people write to them,telling them TO close down!

1 Their pricing scheme is out of date andtheir poor reputation will prevent themfrom ever making it. The recent exposureof their readership figures is just yetanother knock at the foundations of theirorganisation. Latest propaganda materialshows that the Prism towers are crumbling.Expect demolition imminently.
1 Theattributes file -which contains the colourinformation- and the display file -whichspecifies the contents of the characterspaces- are completely independent and areonly superimposed on each other by the TVscreen. Besides, the whole routine takesless than a 50th of a second -the rate atwhich the TV screen is scanned- so thereis no chance of you seeing a digit printedblack out of white then suddenly reverseto white out of black.
1 The workspace is used for general taskslike storing input data and concatenating(running together) strings. WORKSP isstored in 23,649 and 23,650 (5C61 and 5C62in hex) in the system variables area. Whenit is not being used the workspacecollapses to nothing.

1 The whole planet held a memorial servicefor the dead and thier families as theywatched the craft dissapear into the sunon big viewing screens, some of thecolonies in the southern hemisphere werecompletely wiped out and were leftuninhabited for a number of years untilthe population grew large again.
1 The whole island went deathly quiet and hecould feel all the peoples minds were opento his, waiting to hear his thoughts.y
1 The way round this is to POKE the linenumber directly onto the screen. As ittakes eight bytes to PRINT just onecharacter, to simplify the PRINT procedurethe line numbers are all PRINTed in thesame place, out of the area BASIC wants touse. Alongside it is PRINTed the number ofthe statement within the line that theprogram is executing.
1 The variables area stores the values ofthe variables being used in the currentBASIC program. It starts at VARS, whoselocation is held in locations 23,627 and23,628 (5C4B and 5C4C hex) of the systemvariables area. When the program is RUN,the start of the variables area stayswhere it is, nothing below it in memoryneeds to expand, but the variables areaitself grows as new variables are defined.
1 The trace programs listed below are givenin assembly language as well as machinecode. If your assembler is not working youcan feed in the trace program machine codeusing a machine code monitor.
1 The trace routine is not called fromBASIC. It is called from another machinecode routine, which itself is called fromBASIC. And it is this call routine whichredirects the interrupts to the startaddress of the trace program itself.
1 The time travel sequence went according toplan and within an hour they were on thierway home, only Samak and Aleen went intostasis, Coria had to control the craft andJarus worked on the samples to first ofall produce an antidote to the virus thatwas spreading around thier home planet,then grow an immune system that could besafely injected into everyone on theplanet from the tissue and blood samples.
1 The take-off went as smoothly as plannedand in no time they were in orbit aroundthe planet, the course was set and thenthey were underway to the solar system ofmother earth.
1 The system variables are the locationswhich hold the addresses, or pointers, ofthe beginnings of the specific areas abovethem in memory.

Thus helping them to come toterms with thier own experiences and thepossibility of past lives and their alienidentities. Very interesting to start, butthen she went on too long sending half ofthe audience to sleep.

1 The services and contacts here are allin regular communication with AlchemistResearch and are considered reliable andtrustworthy.
1 The service has been going for over aquarter of a year now, and is doing verynicely indeed. James has launched a newlittle A5 magazine called CLASSIX,dedicated to the classic games of old.
1 The series also gets away from the stationa lot more, thanks to THE DEFIANT - aFederation ship, given to the station tohelp fight the Dominion. It was developedfor fighting the Borg, and is one meanship! Not enough for you? Well, it evenhas it's own cloaking device, on loan fromthe Romulan government, complete withRomulan officer!

1 The sequel to Fast Food, this Codies game(again!) is great fun to play, but has astrange bug on completion. The finalscreen of Dizzy appears with weirdcoloured blobs all over it! I've completedthe game several times in both 48k and128k modes, and the screen corruptionoccurs every time.
1 The second thing, is the utilities that come with Warajevo. For Warajevo is more than just an emulator.j
1 The second program will load and print thedata to the printer. Simply change theLPRINT in line 50 to PRINT if you want toview the results on screen.
1 The second edition of the Fountain PDlibrary catalogue is now available. Areasof software covered include utilities forusers of Tape, +3, +D, Microdrive andMultiface, plus general utilities forProgramming, Graphics, Fonts, Sound,Application, Printer routines, Education /leisure, Fanzines and a large selection ofvery high quality games. Each area has itsown section and all titles are listedalphabetically.
1 The routine that turns the main programoff loads the 'l' register with 62 toreturn it to what it was before the vectorwas altered. And the im 1 returns theinterrupt mode to normal.
1 The result is then added to the contentsof the BC register to give the loction ofthe first byte of the character required.The contents of the HL and DE registersare then exchanged so that the HL registercan be used again.
1 The reason Alchemist Research has beensuch a success is because it wasestablished by a user who had an idea howthe perfect service should be run. Wesincerely hope that our service is alsoyour idea of an excellent operation.
1 The program will then ask you for thenumber of bytes your machine code routinetakes up. you can work this out bycounting the pairs of hex digits. Eachpair is a byte. Then you must enter a nameso that your computer can identify it whenyou want to LOAD it back in later.
1 The program we will be using is ZXCOMP.There are lots of optional extras whichyou can use, all of which are in theWarajevo manual, which comes with thecollection. The syntax is:
1 The process of data recovery so is notstraight-forward and requires a fairlygood knowledge of both m/c programming andof the routine in the 48K ROM known as'LOAD BYTES'.

1 The pictures in his head now showed motherearth in the 20th century and pictures ofthier ancestors, 'What we have been askedto do is return to mother earth in theyear 1995 and take some DNA samples fromour ancestors so that we can build our ownimmune systems again. We will have to setoff as soon as the craft has undergoneit's final inspection later today'.
1 The pictures had stopped flowing into hismind now so he asked everyone to removethe crystals. 'Samak, I know that Borokbeat you in the time travel race and Ihope you wont hold any grudges abouthaving to use his craft for the journey,he has proven that his craft will work andyours is only just finished'. Samak lookeda little disheartened ' I was gettingready for a test flight this week, but ifit means the difference between life anddeath for our planet I would rather use acraft that has been proven to work'.
1 The pictures in his head were showingBorok before he set off on his time traveljourney, he was stood by his craft that hehoped would take him back in time, thiswas the first time that anyone hadattempted time travel, it had been spokenabout for centuries but no one knew forsure if it would work.
1 The package comprised of a normal CD case,no inlay, and the CD. Not only did itcontain '3000+ classic Spectrum games',but also includes 201 Windows games, 75Workbench games, lottery predictors andmuch more.
1 The only solution was to contact James,and see if he could supply the original.R
1 The only reason he was chosen for thismission was that he had studied thediseases from thier home planet, using oldbooks out of the archives and visioncrystals.
1 The only drawback was the storms, most ofthe planet was covered in thick cloud andthey only saw the sun for two months outof every 12 in the year, and then it wasconstant, no destinction between night orday, their sun was not as bright as thesun that mother earth orbited, it was onlyhalf the size and glowed an amber colour.The temperature on this planet wasconstant, sun or no sun it stayed at amoderate 57 degrees C.
1 The only difference in her was that shecould move more objects faster and moreprecicely than a lot of people, she hadalso learned to levitate bigger objects,such as humans, and could hold atelepathic conversation with someone atthe other side of the planet whilst doingany other tasks. Her kind could also stayunder water for the best part of a day,breathing the oxygen in the water, whichmade them better construction workers on aplanet with very little land mass.

1 The object of the game is quite simply toget out of the house. Which has beenlocked up tight and you have to find thekey.
1 The next problem is when one looks at theprinter manual you are faced with a wholehost of desirable features which could beprogrammed by software into the printer ifonly you could understand them. Thepurpose of this article is to explain howthey work.
1 The next five instructions give you apause facility so that you can halt thetrace -and the program- at any point. The'in' instruction looks at the variousinput ports. The particular port you wantto look at is the keyboard port which isnumber 254. And the part of it you want toexamine are the keys:- B, N, M, Sym-shiftand Space. So 'ld a,127' loads theaccumulator with 127. This is then used asa paramiter by the 'in' instruction.
1 The needle had no trouble penetrating hischest and only left a hole a few micronsin diameter, next they needed a sample ofmucus from the back of his throat whichwas collected by a small flexible tubethen a blood sample and a tissue samplefrom various organs.
1 The most popular Pascal system for theSpectrum is Hisoft Pascal. It's no longersold, and Hisoft will not have anything todo with re-distribution of the program, sothe SPECTRUM GAME FINDER SERVICE may needto be called upon. Chris Taylor of TRIADDEVELOPMENTS was connected with a PascalUser Group at one time, and has exampleprograms for this system.
1 The modem was a 48,800 bps model. This isjust about the fastest on the market.However, the socket at the back of mycomputer could only handle a top speed of9600.
1 The mod cannot be done to 128 machines byusing the above instructions to fit a+3/2A ROM ... it won't work because ofadditional internal hardware which isn'tpresent.
1 The microdrive map area only exists if youhave a microdrive attached to yourSpectrum. Otherwise CHANS, whose addressis stored at locations 23,631 and 23,632(5C4F and 5C50), moves down to 5BC6.
1 The memory map shown below is a pictoralrepresentation of where things are in thememory. These are not thier exact physicalpositions, as the memory space is dividedup onto a number of different chips insidethe computer. But the map does show youschematically how various parts of thememory are used for different things.

1 The mail shot also makes public attacks ata number of people. These people don'thave a magazine outlet where they can puttheir views forward. Complaints made to MrSherwood are swept under the carpet - somuch for unbiased reporting!
1 The magazine is small, poor quality with asmall team behind it. Their softwarelibrary contains old, out of datematerial. Quite recently, it was exposedthat Martyn Sherwood was recruiting othersto get software for him from otherlibraries.
1 The magazine is now a few months overdue,and letters are being ignored. Thishappened around a year or so ago, andresulted in some very angry customers andcontributors, many of which turned toAlchemist Research.
1 The magazine has a first rate advertisingsection, which is read by around 700readers.\
1 The magazine doesn't only review, theresan adventure section with, erm a review!But, there is a programming section, witha simple routine, which is broken down anexplained. Theres also a glossary ofcomputing terms, covering the IF statementthis issue.
1 The magazine ends with a review of acomputerised diary, although it gave nodetails whether it was a past game orcurrent PD one, and details of nextmonth's bigger issue with more pages andfree software. Alchemist Research hasoffered to help by supplying one of ournon-PD gems.

1 The lower byte, 57, goes into the loweraddress and the higher byte, FF, goes intothe higher address. This may look like anodd way round, but the spectrum finds iteasier to cope with this way.

1 The ld hl,23286 is the address in theattributes file of the character squarebefore the first digit. This is to givethe numbers a border. The number 71 -whichproduces black paper and bright white ink-is loaded into that location. DE is thenloaded with the address of the nextlocation and the BC register is loadedwith 9. The BC register is going to beused as a counter.

1 The judge will find our story true"
1 The instructions ld a,9 and ld i,a loadthe 'l' register with 9. There is noinstruction to load the 'l' registerdirectly with a number. The 9 is taken asthe high byte of the two-byte interruptvector, while the low byte is supplied bythe Spectrum itslf and is normally 255. Sothe interrupt vector points to 9*256+255,which equals 2559. The pointer containedin 2559 and 2560 redirects it to 65129,which is the start of the main program.

1 The game is similar to Jet Set Willy, butyou must collect all objects from eachscreen before moving on. There are lots ofnasties on the screen and you have a timelimit to work to, actually comprised of anair supply, which will expire!
1 The game arrived very securely. Cushionedwith polystyrene, in a cardboard carton,wrapped in strong brown paper was theoriginal H:ATC game! Sadly, the previousowner had decided to 'tastefully' colourin the inlay card with a pink felt pen,but that was hardly James's fault. Whatwas important was that I'd got theoriginal game, in marvellous condition,for only a couple of pounds! I'm not surewhen H:ATC was released, but the inlaystates that it will run on a 16k or 48kSpectrum, which narrows it down to 1982 or1983.
1 The following programs have been removedfrom the Spectrum public domain. Now,there is some quibble about whether thiscan be done or not, with Martyn Sherwoodsaying 'it cannot be done and is illegal'.Really? Funny how so many others, andSOLICITORS say that it can be done! But,then again, Sherwood knows very little.
1 The following program looks at this areaand PRINTs out the number in each memorylocation. Alongside that it PRINTs theASCII symbol corresponding to the number,which shows what you typed in. Note thatthe keywords are not stored character bycharacter as ASCII strings but are encodedas single-byte, or in some cases a double-byte number. These are known as 'tokens'and are translated back to the keywordsautomatically by the Spectrum.
1 The following program allows you to key inmachine code, save machine code programson tape and examine them in memory. Theappropriate CLEAR command must be givenbefore you enter the program. Once youhave done that, entered the program andRUN it you will be asked to supply a startaddress which should be the memory addressabove the one you have CLEARed down to.Remember that the CLEAR command specifiesthe last address of BASIC, and thelocation above it is where your machinecode program should begin.

1 The first of her race was still aliveafter more than 300 years and was lookedupon as a mentor, he had joined with mostof the computer network on the planet tothe extent that it was only his brain thatwas alive and kept in continual stasisstill in his body on a small island of hisown, some of the religious factionsbelieved that he was the re-birth ofChrist and was sent to them to help buildthe planet into what it is today, Coriawas'nt a believer but she still had theupmost respect for him because she was oneof his decendants, as were the rest of herkind.
1 The first instruction in the printoutsubroutine is ld b,8, which loads the Bregister with eight. This is going to beused as a counter while the eight bytesthat make up the digit are POKEd onto thescreen. The accumulator is then loadedwith the contents of the memory locationwhose address is in DE -in other words,with the first byte of the appropriatedigit. And the contents of the accumulatoris then loaded into the memory locationwhose address is given by the contents ofHL -in other words, the appropriate screenlocation. You cannot load the contents ofone memory location directly into anotherwithout putting them into a register onthe way, except with a block load commandthat takes several bytes to set up. Thereis no 'ld (hl),(de)'
1 The final two programs here help you chartand map your way through the mansion. Thefirst program saves off the data from allthe rooms, and their exits. Simply type itin and start the tape before running.
1 The final step is to solder the three endsof the loose wires to the switch - thewire from the IC holder goes to the centreof the three contacts and the two othersto the outers - doesn't matter which goeswhere as long as you do not solder both tothe same contact.
1 The faulty deck syndrome can easily berectified or diagnosed by replacement, ascan the tape itself, though not always ifit happens to be a rare piece of softwareor something you have written yourself.
1 The editor of this magazine has knownDarren for many years and worked with himon projects. It is sure that Darren is notintentionally ignoring people.
1 The editing area is where the editing ofBASIC lines is done. As a line can beedited while it is being keyed in, BASICprogram lines always appear in the editingarea first. When ENTER is pushed, they arecopied into the BASIC program area. Theediting area starts at the E-LINE whoseaddress is held in locations 23,641 and23,642 (5C59 and 5C5A in hex) in thesystem variables area.
1 The easy way is with, of course, the JetSet Willy Editor. Two are available, oneby Paul Rhodes, and available fromsoftware libraries (albeit in snapshotform only at the moment). The other is byRichard Swann and was featured in YourSinclair's PROGRAM PITSTOP.

1 The crew did as she asked and strappedthemselves into thier seats as the craftstarted to speed up and bank to the left,Samak was at his controls ready for Coriassignal to start the time travel sequence,Coria was concentrating with all herthoughts fixed on the controls, Jarus andAleen could do nothing at this stage onlysit and wait as the craft spiralledtowards the sun.
1 The crafts themselves were constructed asgiant vehicles, most were built in theremains of the oceans, hundreds of milesin diameter some of them were built arounda whole island and the soil was fired outinto space once the crafts had beenlaunched leaving massive holes in theplanet. Each craft was built to carry atleast a hundred thousand people and allthe things they needed to survive,including vast forests for oxygen and manydifferent animal species.
1 The contents of the H register are thenincremented. As H contains the high byteof the HL register pair, this effectivelyincreases the contents of HL by 256, sothat it contains the address of the nextpixel line of the digit.
1 The conference was very interesting andhas left me with less cynical views, I'vealways belived that there must be otherinhabited planets in the universe, but nowI also believe that not only are theywatching us, but they are landing on earthand investigating us!

1 The car was started and revved up, butdespite our best efforts we only managedto plough up the mud, spattering the jeansof everyone who was pushing the car frombehind. It seemed hopeless until oursaviours appeared in the form of threeburly Irishmen who were, despite theirapparent lack of sobriety, at leastfriendly and willing to help. With the carin second gear and our motley crew pushingwith all their might, we were soon out ofthe mud. Off went the Emerald Islers toassist the many others who were in thesame situation.

1 The bottom line, is that it emulates both 48 & 128 speccys, so I will concentrate onthe trimmings of Warajevo, that make it stand out from the crowd.
1 The block load instruction 'ldir' loadsthe contents of the location pointed to byHL into the location pointed to by DE,increments HL and DE, decrements B andchecks that it does not, now, contain 0.If not, it repeats. In other words, itcopies the black paper, bright white inkattribute from the first character squarealong the next line.
1 The best suggestion would be to copy thecontrol program on to a short blank tape.You can then load this in when desired andleave your original AlchNews cassette atthe last part you read. The controlprogram doesn't care about which part isloaded, so long as the ANxx.C or ANxx.Dpart has been loaded first. (xx=issuenumber).
1 The authors feel that Warajevo is as good,if not better than Z80.A
1 The authors could only program Warajevo on a 286, on the 2-3 hrs electricity per night that their generator could provide.}
1 The attributes area controls the PAPER andINK colours of each of the screen's 768character areas and whether the display isFLASHing or steady, BRIGHT or normal.
1 The advantage of UCSD PAscal is increasedportability, but the disadvantage is thatthe generated code is slower in executionthat a native code compiler.
1 The WARAJEVO Spectrum emulator comes witha utility called ZXCOMP, a program whichcompiles Z80 based snapshots to standardEXE files, which can then be run by a PC,from DOS or Windows, without the aid ofany emulator.

1 The Spectrum uses the BASIC keyword USR,followed by the start address of themachine code program. USR returns thevalue of the BC register once the machinecode routine has been completed. In itselfthis is not very useful, but it does meanthat the machine code program has to runwhile it's being worked out.
1 The Spectrum has special problems when itcomes to PRINTing on the screen during aninterrupt routine. It has discrete outputchannels for PRINTing on the bottom of thescreen and the top. And changing channelwhile a program is RUNning can lead toproblems.

1 The ROM contains the computer's operatinginstructions and the interpreter thattranslates your BASIC programs intomachine code. It also imposes a structureon the rest of the memory which can beseen in the memory maps below.
1 The RAM is divided up into areas, each ofwhich has a specific job to do.I
1 The Interface 1 bug is caused by a missingLD C,#FE instruction. Without this,pressing a key to pause locks it upforever by reading from port 0.
1 The Human Race.
1 The HL registers are then loaded with thecontents of memory locations 23621 and23622. These hold the number of the lineof BASIC currently being executed.
1 The HL register is then loaded with thecontents of 23623 and 23624, which is thesystem variable that contains the numberof the statement in a line of BASIC thatis currently being executed. But themaximum number of statements that can beincluded in a line is 128 on the Spectrum.So the high byte -which is in fact thevalue of another system variable- must beset to nought with the instruction ld h,0.The routine that works out the decimalcharacters and pokes them on the screen isthen executed again. But this time it iscalled at the lable 'statno' as only threedigits are needed.
1 The GOSUB stack stores the number of theline the computer has to return to when ithas completed the subroutine.q
1 The ESC part of the code is the mnemonicfor EPSON STANDARD CODE and is alwaysrepresented by CHR$27. This code precedes99% of all code combinations and toachieve the example given above:
1 The Beehive does contain honey for thebread. But disturbing it will bring outsome angry bees. Too many stings can befatal.
1 The Bathroom
1 The BC register pair holds 16 binary ones,minus 1000 in decimal. So when you add anynumber greater than 1000 to it, theregister pair overflows and sets the carryflag.
1 The BASIC program area holds the currentlines of any BASIC program you've keyedin, and its size depends on the length ofthe program. It starts at the addressgiven by the systems variable PROG, whichis held in locations 23,635 and 23,636(5C53 and 5C84) in the system variablesarea. This points to 23,755 (5CCB in hex)if no microdrive is attached.
1 The BASIC listing is as follows, for thosewithout an assembler:?
1 The BASIC line number now in the HLregisters is in hex, so it has to beconverted into decimal before it isprinted on the screen. To do this itstarts by working out the fourth digit, inother words the thousands. and to do thatyou subtract 1000 from the number until itwon't go any more and count the number oftimes you do it.
1 The A register now contains the value ofthe thousands digit. By adding 48, you getthe ASCII code of the character. Thecontents of the HL are what is left over,and they are saved by pushing them ontothe stack - so they can be recalled whenyou want to work out the hundreds, thetens and the ones. Then yet anothersubroutine, 'print', is called.
1 The A register is then incremented andacts as a counter. Then 'jr c,prtlp'checks the carry flag and makes a reletivejump if it is set.
1 The 2A and +3 have two 2 x 16K ROMS, whichare situated to the left of the Z80 chip(viewed from the front of the machine),IC 7 and IC 8.
1 The 254 is data that is actually writteninto the program. Altogether 'ld a,127'and 'in a,(254)' loads the value of thefive keys into the accumulator.
1 The 128k version of this classic Imaginebeat 'em up featured a bug of sorts. Asjust about everyone knows, pressing thezero key takes you to the next level. Thebug is that if you choose Sinclair 1 youcan't punch or kick, because pressing fireis equivalent to typing zero (try doing itin BASIC) and so you always go to the nextlevel!
1 The 'ret' returns the microprocessor fromthe subroutine and ld hl,posn loads thescreen position stored in posn into the HLregister. Then the contents of posn areincremented by the indirect instructioninc (l).
1 The 'pop hl' pulls the contents of thetop two memory locations off the stack andputs them into the HL registers. Lookingback, you will see that the last thingpushed onto the stack were the contents ofthe HL register when it contained theremainder after the thousands digit wasworked out. The 'ret' then sends theprocessor back to the line that readsstatno ld bc,-100 and the process isrepeated to work out the hundreds digit.When that has been printed on the screennext to the thousands, the tens -and thenthe ones- are worked out in the same wayand printed next to them.
1 The 'add hl,bc' subtracts 1000 from thecurrent line number which is in HL. To add-1000 is quicker and easier thansubtracting 1000 as you don't have tobother about checking the carry flag.
1 The response has been tremendous, themailbox has been overflowing daily! AFireview created reproduction follows onthe next page.
1 The program is supplied as is, andtherefore I will not be responsible if anyof your discs are corrupted. In additionto this I explicitly disclaim anythingthat can be disclamed.
1 The program gives a MAIN MENU of 9separate functions which are furtherbroken down into sub-menus,which makes iteasy to use by following the on-screeninstructions.
1 The other system is known as UCSD(University of California San Diego)Pascal. In this system, the Pascal code iscompiled down to the code of ahypothetical computer known as a pmachine, and the completed code is knownas p code. This means that the compilerthat is necessary for the compilation isthe same irrespective of the host machine.In fact, all of the UCSD system is,itself, written in Pascal, and each hostmachine has a simple program writtenspecifically for it.
1 The next step, once the two IC's arecoupled, is to solder a 10K resistor fromboth pins 20 to pins 28 (5 volt positiverail). Once done, cut two lengths of wireand solder one apiece to pins 20.
1 The nearest convenient number is 400,which is 1,024 in decimal and representedby 1 with ten zeros after it in binary.This number is defined as 1K.
1 The main program starts with theinstruction rst 56. This makes the micro-processor perform its normal interruptroutine - scan the keyboard and update thesystem variable clock. If you don't ensurethat the keyboard is scanned, it isdisabled and you can't edit BASIC programlines.
1 The instruction ld de,20726 puts theaddress of the screen position immediatelybefore the fist one you are going to POKEa digit into, into the DE register. As theprogram has to refer back to this later,it is stored in the variable 'posn' withld (posn),de. There is no instrction toload a variable or a memory loacaton witha number directly as you would need togive two pieces of data with theinstruction. Loading memory locations withnumbers must be done via a register.
1 The games which are going around areactually the games from the Spectrum -same graphics and everything!q
1 The following routine will scroll thescreen backwards - that is from top tobottom rather than from bottom to top.z
1 The following routine tests on whichSpectrum a program is running and whichmode is used. It further checks wether theprogram is running on SAM or an Emulatorused by a PC or another machine.
1 The first statement is obeyed if thecontrolling expression is true or if theexpression is false the second statementis followed. You can see from the BNFdiagram that the ELSE is optional so analternative to if-then-else, is if-then
1 The contents of 'posn' -the screenlocation for the first digit- themselvesare then loaded into HL. And the actualprint routine, called prtout, is called.
1 The conference consisted of severalspeakers who divulged thier experiencesand opinions to the audience.q
1 The calculator stack is used to holdfloating point numbers, five-byte integersand five-byte sets of parameters whendealing with strings. It starts at STKBOT,whose address occupies locations 23,651and 23,652 (5C63 and 5C64) and ends atSTKEND, which is found in 23,653 and 23654(5C65 and 5C66).
1 The LENGTH of the envelope effect isplaced in registers 11 and 12, the lower 8bits going into 11 and the upper 8 into12. For example, if we wanted to have anenvelope length of 8000, we would put avalue of 64 into register 11 (upper) and31 into register 12 (lower). 8000 is64+256*31 in case you were wondering orhave run out of fingers!
1 The BBC apologises for the break intransmission of this programme. Ourengineers are currently repairing thefault. In the meantime, here is some lightmusic.
1 The +16 sets bits 4 of the volumeregister, which enables envelope control.S
1 The problem is
1 The golden rule of hacking BASICprotection systems is always to use 48BASIC, even if you have a 128k Spectrum.In 128k mode, although embedded colourswill not alter the listing, it's very easyto cause a crash by listing a program witha line numbered 0 or one which contains an"invalid" colour code (eg a CHR$ 16followed by a character above CHR$ 9).
1 The following
1 The Windows games
1 The 'ei' instruction enables"
1 Thats why the second of the two memorylocations in the program above ismultiplied by 256, otherwise the Spectrumwould return the decimal equivalent of FF,rather than FF00.
1 That's it ! The above theory will alsowork with those people who have got anAtari ST and a copy of 'Magic ShadowArchiver'. I am not sure if the Amiga'Disk Masher' is able to read foreign diskformats, but if anyone can clarify thisfor AlchNews 21
1 That's all I think. Bye, bye!
1 That's just about all
1 That was before they realised that theglobal warming had gone too far to doanything about, so they moved to anotherplanet, this one. That was over eighthundred years ago, in the year 2945.
1 That is the list of commands as it standsat the moment, as to the future - whoknows?Z
1 That done, the processor returns to wherethe lineno subroutine was called. Thevariable posn is then loaded with 20731-the address of the screen locationcharacter spaces to the right of where theline number printing routine started. Thisleaves room for four digits containing theline number and one space.

Alchemist Software are alsotermed a neutral group, who do not alreadyrun a magazine, so are logically a betterchoice.

Next came a tremendous explosion,knocking the van onto its side and causingbricks and tiles to fall from nearbybuildings. By now, ambulances and a fireengine had arrived on the scene, but themachine had become a melted, broken messof metal and plastic, and John Murray andhis research were gone.

1 So, when you do read AlchNews, PLEASEfollow these guidelines:B
1 So, what steps can be taken to recover alost tape file if the deck is not at faultbut the ROM keeps detecting something'samiss and refuses to load it?
1 So, welcome to my new spot. Wipe your feetand take a seat! I was going to write alittle short story about brains and memorythis issue, but I needed to get some moredetails on PC's hard drives, and thisissue is already chokablok with SFstories. So, next issue it is.
1 So, the modem went back, especially sincethe salesman told me that it was a verygood deal, yet the same package was `20cheaper in the relatively more expensiveBYTE computer shop!
1 So, meet the new "Roy's Rantings"! Inreturn for this coveted spot, I promisedAndy that I wouldn't disclose his affairwith a married woman in Chesterfield. Hereally is a womaniser you know.
1 So, lets take a look at all those Willies!*
1 So, if you have a snapshot from a recentversion of Z80, or any other emulator,first make sure that it is a valid Z80file. The utility CONVZ80 is supposed toconvert between newer Z80 formats to olderones, but tests failed.
1 So, how come I know so much about theScottish demo group Technium 220 thesedays? Well, despite my wholly Berkshireorigins, I have now joined them. Andytells me his new role as part of theUnited Minds is a PR ploy (or something!)as he will be doing no work whatsoever,but I, yes I, am a graphic artist! No, notan artist but an artiste - that soundsinfinitely more sophisticated...
1 So, as I was saying, if you do indeed havetwo identical blocks which are damaged insome way, using this approach it should bepossible to recovery enough data from themboth to rebuild a complete and error freefile. If not, at least you will havereclaimed almost all of what waseffectively lost.
1 So, I stuck it out with this for a fewweeks, used it mostly for EMAIL withcurrent and new friends, but kept awayfrom COMP.SYS.SINCLAIR.
1 So, the modem was re-sold and I amcurrently off-line. CompuServe inform methat they will be installing a faster,dedicated node in Sheffield in the nearfuture. So, perhaps when this is so, andI've speeded up my PC's communicationsport, A.R. will be back on line.
1 So, Teledisk is loaded, and you'veselected the 'BLANK.TD0' file .. if not,then do so!_
1 So you nedd to go onto the roof to get theoiling can although this creates the firstproblem. How to get back inside. It has tobe done though so that the oiling can canbe used elsewhere in the game.
1 So when the input from port 254 is loadedinto the accumulator, it is compared to252 by 'cp 252'. If the accumulator doescontain 252, the zero flag is set.
1 So what I thought I would do is explainthe relationship between the objectlocations and problems to be solved.x
1 So what follows is from memory and anyommisions will have to be dealt with nexttime ( Assuming I make the deadline eh.Andy )
1 So the contents of the high byte, in23622, are loaded into the accumulator andthe instruction bit 7,a looks at the mostsignificant bit. If this is 1, no BASICprogram is RUNning. The 'bit' instructionlooks at the bits of a particular memorylocation or register. For example bit 4,atests the fourth bit of the A register.
1 So now I'm very happy with my purchase.Although the tape will never actually beloaded, it was worth it for the (verylengthy) instructions. Without which, thegame would be useless.
1 So if you read this, M
1 So if you need to identify 64K memorylocations, you could number them from 1 to65,536 in decimal. But as these numbersthemselves will be used by the computer itis more convenient to number them in hexfrom
1 So first of all you load the BC registerswith -1000 and call another subroutine,prt, to do the repeated subtracion.v
1 So far, the sliders have been to an Earthin an ice age, one where women rule due tomumps making men sterile, where SanFrancisco is a penal colony and one wherethe British won the American war ofIndependence. It's very much in the way ofQUANTUM LEAP. Theres far more in the storythan special FX, which makes it veryaddictive. The show stars Jerry O'Connellas Quinn Mallory, the student inventor ofthe device, with John Rhys Davies as plumpEnglish professor / lecturer MaxamillianArturo , faded pop star known as 'TheCrying Man' and our hero's female friend.
1 So come on, write and tell me what aspectsof hacking you would like seen covered andit shall be done if it is within my field.~

1 Quite recently, Martyn Sherwood has beentaking a 'new' angle on the scene. He istrying to appeal to groups and customersto make a choice and boycott the servicesof Alchemist Research. His writings showthat he is wanting groups to make achoice. However, this quite obviouslyshows a flaw in his appeal. The fact thathe is making such an appeal shows that itis falling on deaf ears and that he is thelosing side. It shows that people areignoring his campaigns and want nothing todo with him.
1 Quit Z80 and run Z80, version 2.01. It'savailable from all sorts of outlets,Alchemist Research has a copy, along withWarajevo, should you need it. It'srecommended that you have the Warajevoemulator in a directory called somethinglike C:/WAR (easier to type), and perhapsZ80v201 under C:/Z80201.

1 Problems like this generally occur inadventures in some sort of logical orderso you can progress furthe in the gamewhen solving each one. To make it harderthere is usually a limit set on the numberof objects that can be carried so you haveto retrace your steps several times.
1 Probably the most famous cheat of thegame, is the 'telephone number'. Asequence of numbers is typed on the firstplaying screen, which then allows you tojump to any screen in the game.
1 Prism has copied Alchemist Research byclaiming to assist other groups launch andestablish themselves. However, of thegroups they have helped, they have eitherfailed to launch, on the verge of collapseor folded.
1 Prism - an outfit run by a man who speaksin whispers when you're listening andbawls his head off when you aren't; whosedisks are like the proverbial curate's eggand whose nature is addled to the core -professional? Someone definitely needs awhite stick! Alchemist Research stand forfreedom of speech, not censorship ofopinion; open discussion, not stifling ofdissent; willingness to reveal the truth,not keenness to conceal the facts - or youwouldn't be reading this article. Inshort, Andy's commitment is to givingeveryone their fair say - including Mr.Sherwood if he cares to write in (but ofcourse he never does) - so he gets my voteevery time.

1 P-RAMT is the physical top of the RAM, inother words there are no more memorylocations on the Spectrum's chips afterthis point. Although P-RAMT is fixed, asfar as the Spectrum is concerned it is asystem variable with its address stored inlocations 23,732 and 23,733 (5CB5 and 5CB6in hex). And you can POKE values intothese and other locations to make a 48KSpectrum think it's a 16K machine.
1 Overall: For their first attempt at a tapemagazine, top marks!>
1 Overall, the magazine is similar to theearly issues of AlchNews (prepared inBasic). But, it's an interesting read and,should the programming team behind it havethe time, will develop in to a leadingelectronic magazine in time.

1 Over the next day and half the crewchecked and double-checked the equipmentthey would use, Jarus went over his samplecollecting instruments, and used the"Medi-bot" on a lifelike dummy of 20thcentury man, making sure that theprogramming was able to take samples fromthe various organs without leaving anyscars or visible tissue damage.

1 Ooh, how low! <Not as low as my low, lowprices! *SNIP*>9
1 Only joking!, I didn't see SHOWGIRLS, I dohave SOME taste you know!.D
1 One possible problem might be that thecode which is loaded and RANDOMIZE USRcalled isn't the actual game. For example,Firebird hexadecimal loaders (eg BubbleBobble and Rick Dangerous) load thespecial hex loader code and call that,which then loads the game as a set ofheaderless files. This is similar to point11 but the code is actually loaded ratherthan stored in a REM or POKEd into memoryfrom BASIC.
1 One of the most popular 'shareware' (VERYdebatable) games knocking around on the PCof late is DOOMDARK'S REVENGE and LORDS OFMIDNIGHT, by Mike Singleton of BeyondSoftware. Understandable, as the graphicsare very well presented, colourful, andthe game is so playable and fast, quiteunlike most strategy games!
1 One of the major plus points
1 One of the easiest bugs to spot with atrace is an infinate loop. If you see thetrace going over and over the same numbersyou will know that you have got somethingwrong in a GOTO statement. Other things towatch for are sudden jumps to another partof the program, conditional IF...THENs setto the wrong condition and lines not beingexecuted at all.
1 One of the conditions which Andy Davisagreed to when I started out this articlewas that he would not see it until it wasactually featured in AlchNews. So, Andydoes not know whether this is good or bad.But, it does show his trust in me, and hisconfidence in who is right or wrong. IfAndy was the slightest bit concerned aboutme attacking him in front of hisreadership (it's approximately 783 by theway, not including the subscriptionshandled by the other software libraries,Internet readers and casual readers), doyou think he would allow me to do this? Ofcourse not.
1 One of my family still had not made anappearance, so we had to move the car (nowladen with new purchases) to the overflowcar park, find a space, return to thetrees and wait. It was now half past tenand we were becoming very irritated. Justthen, the final family member joined us,complete with Levellers tape, incensesticks and other junk. <Sounds like Allie.She buys that kind of stuff. Ed?
1 One of Codemasters' well-known simulators,Boxing brought in complaints from manybuyers who recognised this so-called "newrelease" as Superior Software's By FairMeans Or Foul with an altered title page.David Darling of Codies cleared the matterup by offering refunds and commented that"the game was a new release forCodemasters". H
1 One interesting point to note, however, isthat Prism claims to work closely withthese two organisations, which could bethe reason they are in this current state.Prism were also involved with the IMPERIALmagazine. What happened to that? Foldedafter the first issue!
1 One idea I had was to write a "DiscChange" routine, a bit like the +3 one, sothat even if you only had one external3.5" drive, you could "effectively" run a2 disc drive setup. I'm not entirely sureof the benefits of this, but it would beinteresting to implement the copy routine(sighs..)

1 Once you have obtained the standard loadermentioned at the beginning of thisarticle, save it before running if youwant to keep it! First, though, you candelete any REM lines which contain onlymessages (not machine code!) as these willnot affect the program's performance. Youshould also get rid of any POKE statementsto addresses 23610, 23613, 23614 or 23659,as these make the computer crash if BREAKis pressed.
1 Once you have keyed in your machine codeprogram and checked that there are noerrors in it by examining it in memory,you will want to run it. But it will notrespond to the usual RUN command as thatis a BASIC instruction and will only RUNBASIC programs. special instructions areused to run machine code programs.

1 Once it was perfected, the immune systemwas also introduced into the drinkingwater and was bred back into the newgeneration of humans.
1 Once it has been given the go-ahead, theprogram disables the interrupt with the dicommand - you don't want your interruptroutine being interrupted.

1 Now, Alchemist Research. Launched back in1986 by Andy Davis. Built up the entireempire alone, with hard work anddedication. Created Alchemist Softwarewith only a small handful of titles andbuilt it in to the largest Spectrumsoftware library in the world. Set upAlchNews with just 20 readers to beginwith (the same figure Prism has now!),from a small magazine to one which is nowthe biggest anywhere. Each issue containsmegabytes of information and there aredozens of contributors queueing to gettheir articles included.

The forestshad been placed in huge domes along withthe animals that had survived the journey,they were down to no more than forty fivethousand different species when they hadsettled on New earth but even then anotherfifteen thousand died out.
1 Now that we know how this circuit can beprogrammed in BASIC, lets get down tobuilding it. The simplest approach wouldbe to build this circuit as a module,allowing the Speccy to power it with it'sinternal 5v supply. A suitable piece ofstripboard measuring 8cm*8cm was used inthe prototype, with the edge connectorsoled along one edge allowing the board tosit vertically behind the computer.

But this numbermust have come from somewhere in yoursubconscious mind!

1 My theory is that there is no such thingas true randomness. For example, go andlook at some trees in a park. Takingmeasurements of length, height andcircumference will yield no formula forany of these in terms of age, but thisdoes not necessarily imply random growth.The elements and environment have shapedeach tree into its unique form, notrandomly but as part of an infinitelycomplex sequence which we, being unable topredict, call "random".

If you feel that you must,don't be afraid to show your feelings.Andy is not a vindictive and bitterperson, he wouldn't swamp you with hatemail. What's the worse that can happen toyou if you do make the right choice -regular junk and hate mail from Prism.Just bin it and make a complaint to therelevant body who handles junk mail!

1 Marty looked blank.
1 Marty had been getting anonymous phonecalls, jibes and sneers, so he went downto the telephone exchange to see whatcould be done
1 Mark's conscience, however, would appearto have got the better of him in the end,for soon after these events, he wrote toAndy profoundly apologising and takingfull blame for his actions. Andy forgavehim and accepted his apology, and thatwould have, and indeed should have, beenthe end of the matter, had notconscientious, fair-minded Martyn Sherwoodstepped in. Guess what he was up to?Making the most of the original storywhile furtively pretending not to know anybetter - and still doing it even to thisday!

1 Jarus was'nt prepared for this kind ofproblem, the needle was retracting and waswithin a millimeter of coming out of thebone when the man moved in his sleep,snapping the needle a few microns belowthe skin.
1 Jarus was the first to enter the dome, itwas his task to lay the vision crystals inplace for everyone else. He sat in hisseat and set about moving the crystals oneby one with telekenisis, trying to movemore would have been impossible for him,he did'nt have the skill that Coria had,that is the reason why she was chosen topilot the craft to mother earth.
1 Jarus was the first inside his suit andwhen he had his whole body inside, theopening in the back closed and fusedtogether to make the whole suit seamless,then the suit shrunk to fit his body likea smooth top skin.
1 Jarus thanked him and turned to Aleen,'You have been teaching about the 20thcentury in your history classes for thelast 17 years so you will be our guide onthis mission', Aleen thanked him and saidit would give her a first hand experienceto tell her students about.
1 Jarus sat at the medi-bot control panel atthe other side of a glass wall and startedthe proccess of collecting the releventsamples.
1 Jarus rushed past the child and throughthe door as he took the crystal rod fromhis sleeve._
1 Jarus looked through the viewing panel andcould see that the craft had slowed downto under light speed as it came intoMother Earth's orbit, Coria brought thecraft to a halt 30,000 miles from thesurface and looked in awe at thisbeautiful planet that was once the home ofher race, she had never seen suchwonderful colours as she could see now, itwas even more splendid than the holo-picsthey had at home, she turned to Jaruswhose eyes were also fixed on the planet,'This is the most beutiful thing I haveever seen, how could our ancestors destroythis?' she asked almost close to tears,Jarus looked into her eyes and could seethat the red gleam had turned to brightblue, like the oceans on the planet, whichmade her look even more lovely than he hadever seen her. He was so taken aback bythis that all he could say was 'Ignorance'before a tear ran down his cheek and ontohis lips.
1 Jarus looked at the probe locater, 'It'sthis way' he said as he started to walktowards the row of buildings, 'What ifsomeone see's us?' Samak asked as hecaught up, 'There is no-one awake to seeus' Coria said 'I can feel every-onesdreams, and no concious thoughts, so weare quite safe as long as we don't wakeanyone'. Samak was content with the answeruntil he heard a strange noise that madethem all jump, 'What was that?' askedJarus, 'It sounded like an animal of somekind' Coria said as she looked around.
1 Jarus looked at her, 'Our ancestors onlyused a portion of their brains duringconciousness, and it was mostly seperatedfrom their unconcious thoughts, so what weare going to do is take somebody whilstthey are sleeping, keep them in anunconcious state whilst we take thesamples, then return them to theirsleeping quaters. If they do rememberanything it will seem like a dream to themso there wont be any lasting damage'.
1 Jarus held a small metallic rod near theadults, 'The female seems to be heavilyinfected but the male is showing signs ofrecovery, we'll take the male for thespecimens because his immune system ismore active' with that he took a crystalrod from his sleeve and placed it againstthe females forehead for a second, thenthe males, 'This will keep them asleepuntil we return him'.
1 Jarus had already opened the door to thestasis room and was on his way in whenAleen and Samak caught him up, Aleenstopped to talk to him as Samak went tohis pod saying that he would see them in afew days. 'Will Coria be alright over thenext couple of days with no one to talkto?' she asked looking concerned. 'She'llbe fine, you know her kind they can view adozen film crystals, read the newscrystal, hold a conversation and do a fewother tasks at the same time so sheshould'nt get bored with all theactivities on board' Jarus laughed,'besides i've told her to wake me if she'slonely'.
1 Jarus did the same, as the glass covercame down he placed the two crystals onhis forehead and closed his eyes a fewseconds before the gas rushed in and frozehis body, he did'nt feel the cold or anypain because of the speed at which hefroze. Although his body was in completestasis his mind was going over the missionand the history lesson that Aleen hadprepared before they set off.
1 Jarus continued, 'The disease that Borokhad brought back was not as fatal then asit is to us now, the old humans used tocall it a "common cold" and the worst thatwould happen to them after contracting itwas that they would find it difficult tobreath because there sinuses would beblocked by mucus and they would also havea sore chest and throat. Not many peopledied from it as they all had an immunesystem in thier bodies that fought anyalien bacteria, because of evolution noone on this planet can outlive thisdisease and it's spreading fast'.
1 Jarus and Coria's daughter had betterpowers than her mother by the age of 12and thier 7 year old son also looked asthough he may surpass her powers.

1 It's a fail-safe device really, becausewhen a BASIC program has finished RUNningthe number of the last line executed isleft in the system variable until anotherdirect command is entered.

1 In almost any professional game, youcannot break into the loader without acrash. What you have to do is, rather thanuse LOAD "" (which is also what the TapeLoader option does on the 128k models),use MERGE "" instead. Merging a programcombines its lines with those of theexisting program, so doing it with nothingin memory ought to be the same as loadingnormally. The trick is that MERGE preventsthe program from autorunning and willreturn you to the BASIC editor instead.

1 If you want to keep this machine codemonitor, you should save it seperatelyfrom your machine code programs on tape,or disk in the usual way. The 'Save BytesTo Tape/disk' option in the program itselfonly saves the machine code routines thathave been entered with this program.
1 If you want to enter machine code youpress 1. When you have given the computera start address and pressed ENTER, startfeeding in your machine code. Thisconsists of pairs of hex digits and youmust feed the digits in two at a time.
1 If you spot an error and want to correctit, press ENTER and the program willreturn to the menu. Press 1 to entermachine code and the computer asks for astart address again. This time you give itthe address of the byte that is wrong. Ifit's a whole series that you want tocorrect, just give the address of thefirst byte of the series. You can enterthe correct bytes, one after the otheragain.
1 If you select option 2 to examine thememory, the program will ask you again fora start address - this time the start ofthe memory area that you want to look at.
1 If you read part 2 of my hacking article,where I covered 'LOAD BYTES' in very finedetail, you will be aware from that, thatit is possible to enter this ROM routineat several differing points and, providingyou do so with certain registers setaccordingly, can either load in an entiresave or jump in at any point. Both theseoptions have to be adopted to recover lostdata - the normal entry address being usedto load in the block up to the point of anerror and a jump being made back into theloader, once the corrupt part of the tapehas passed by, to load in the remainingbytes.
1 If you press any key except ENTER, theaddress of the location eight on from thestart address will be printed, along withit's contents and the contents of theseven subsequent bytes. This appears on aseperate line underneath and you can PRINToutthe whole of your machine code programline by line in this fashion.

1 If you do use the ASCII character code becareful to get upper or lower case right.For example if you inadvertantly usedlower case "w" in the example above youwould get double height characters insteadof double width! Perhaps for this reasonit is safer to use the CHR$ version. Somecode combinations require an extraparameter and this is referred to as "n"in the Printer Handbook. The value of "n"determines a particular function and canhave different values as quoted in theManual.

1 If you have a Pascal system for yourcomputer, you can try keying in one ormore of the examples. When you have typedthe source code, compile it and run theprogram. These program should work for anyPascal system accepting lower case input.
1 If this is true, then every event whichhas ever taken place must have beendestined to do so, as if the universe was"programmed" in advance. Perhaps somesmall occurrence such as the death of onebird six thousand years ago caused a chainof events leading ultimately to yourbirth. But which part of the sequencecaused the bird's death? And which partcaused that event itself? The sequencemust have begun somewhere.
1 If there is only a single error, you couldcorrect it by BREAKing out of the monitorprogram and POKEing the appropriatelocation with the correction. Rememberthough, you have to POKE in the decimalnumber.
1 If the most significant bit of the mostsignificant bytes of the current BASICline number system variable is 0, the zeroflag is set and jr z,go jumps to the nextoccurrence of the label 'go', which is atthe start of the main program itself. Andif bit 7 of the accumulator is 1, the zeroflag is not set, the jump does not occurand the program moves onto the nextinstruction. This pops the contents of thestack back, restoring the AF registers tothier former values and returns to theBASIC interpreter.

If you optfor soldering both IC's together directly,leave a slight gap between the two so aircan circulate through this space.

1 Hello and welcome to the lack of AdventureSpot which due to a change of job for thethird time in as many months and the timeneeded to look after a familly of 3 kidshas barely been looked at since the lastissue.
1 Hello again. Below is the short programcreated in the last instalment. It simplyuses channel A to make a continuous sound.This time, I want to take you throughsimple Envelope contrl and the use ofnoise.
1 He's also made the first move by publiclyattacking David Fountain of the FPDlibrary. Although Mr Fountain has had somenasty experiences with Prism, he's kept itto himself, but Mr Sherwood has made themistake of making it public. Now, MrFountain is in a position to explain tothe masses why he is no longer friendswith Mr Sherwood.
1 He was snapped out of his thoughts byAleen, 'Are you going into stasis with therest of us for a couple of days?' sheasked, 'or do you want to stay awake forthe journey?'.
1 He was obviously picked as a first speakerto fire up the audience and get theirminds ticking over.g
1 He was just thinking about the humans thatwere left behind on mother earth, if theyhad evolved differently, or survived atall, when Samak entered the dome, closelyfollowed by Aleen and Coria.
1 He was glad that she was coming along.&
1 He was completely riveting, you could haveheard a pin drop as he was talking.M
1 He used to have a lot of friends
1 He threatens legal action
1 He showed us film footage of U.F.O's fromNew Mexico, at first I mistakably thought(being the cynic that I was) that thesewere fire flies as there were hundreds ofthe darting about the sky, but on slowingthe film down these things looked likeeither spirals or chain links which wouldtwist or bend in various directions. Itwas pointed out that these things werethousands of feet away from the camera sothey must have been huge to seem so close.More film footage showed another "craft"which seemed to be rectangular in shapeand as wide as a house which hovered a fewthousand feet above the ground.
1 He sent this mail shot to all kinds ofpeople, including those who aren't evenconnected with the Spectrum. One of whichwas a Mr Middleton of Persona Software.When he received it, he rang Mr Sherwood,asking what it was all about and why hefelt he should receive a copy. It'sreported that when confronted in thismanner, Mr Sherwood squirmed as hecouldn't answer the questions put to him.
1 He placed the fourth crystal at the farend of the table and sat back to wait forthe others to arrive. As he looked aroundthe dome he saw a holo-pic of the motherearth, before it had become the desolatewasteland that made the humans desert itand move to this planet at the other endof the galaxy. It was more beautiful thanthis planet which his ancestors had chosenfor thier new home.
1 He opened the door to the adolecents roomjust as she was sitting up in bed, 'Dad?what's happening?' she said as she triedto focus on the figure coming towards her.'Go back to sleep, there is nothinghappening' Jarus put the thought into hermind as he placed the rod to her forehead.For a split second she looked at him witha puzzled look on her face before fallingback to sleep.
1 He looked at Samak and Aleen and could seethat they were close to tears also beforeundoing the buckle on his strap andwalking to hold Coria in his arms whilstthey looked at Mother Earth together.
1 He knows nothing and the AMERICAN bookhe's getting half of this from is derivedfrom AMERICAN PC SOFTWARE - hardly anybasis for Spectrum software.
1 He found that the controls of Borok'scraft were very similar to his own plansand could'nt help thinking that Borok hadsomehow got hold of his plans and copied afew ideas of his own, but he dismissedthis idea almost immediatly as he did'ntthink that Borok was the kind of person todo such a thing as steal another personsidea.
1 He finished his talk with a half hoursession of questions and answers, most ofwhich we had to miss as we had a train tocatch. <I hate B.R!. Paul>
1 He copyrights his letters
1 He contradicts himself.
1 He can't back up his claims,
1 He also pirates games.
1 Having said that, the most recent episode (at the time of writing), showed Mulder up to his old tricks, risking his life in the pursuit of Alien beings, just a shame it ripped off the ROSWELL alien autopsy footage...
1 Having recently fallen victim to certainspineless creatures which prey upon thereputations of the innocent, I would liketo take this opportunity to warn AlchNewsreaders about a dangerous species ofpredator that roams
1 Having read issue 18 of your acclaimedpublication, I must admit to being morethan a little disappointed. While thetextual content was universally of a highstandard (especially those articles bythat genius Paul Howard), the option tochange the music on a +D disc system wasmediocre to say the least.
1 Having a properly working assembler isessential. Many of the following chaptersdepend on it and it is vital that youlocate all of the bugs in it now.
1 Have lost them, one by one.
1 Hard cricket balls break glass windows soyou can get back into the house ( They canalso break other types of balls as I canvouch from painfull experience )
1 Hang on. What this rumbling from your bum?Must be the mouldy bread having an effect.Better get to the loo pretty smartish.Hope you remembered to put some loo rollin there or your going to be stuck inthere a very long time.
1 Hang on a mo. The bus is already at thebus stop. Better run for it or you'll missit. These bus drivers don't hang aroundand I should know ( In joke )

1 Half an hour before take off they were inthe docking bay standing beside the hugecraft that would take them to motherearth. The whole of the craft wasconstructed out of Diamontanium whichwould reflect the heat and light of thesun, it was also one of the strongest andlightest materials known to them whichwould enable them to travel at immensespeed without disintergrating.

1 Good morning, class 3A. Today I'm going tolook at some classic, and some completelyunnoticed, mistakes in Speccy games. Notall of these mistakes are programmers'errors and bugs; many are factualslip-ups. Anyway, here are the top tenSpeccy game errors of all time.
1 Go to work , Great reward eh.
1 Go from me to you, for the appallingwriting in the doc file - you know whatthey say - never, ever, ever let theprogrammer write the instructions - if youdo, it's bound to be badly written!!!

1 From the moment they stepped out of theshuttle, all they heard was "Good luck,and come back soon", it was obvious thatthe party had been going on for some timebefore they got there. The council calledthem up to the raised platform foreveryone to see them and asked them to saya few words. Jarus was pushed forward bythe rest of the team and Coria raised himhigh in the air, he had no choice now, hehad to say something.

1 For we'll prove all we've said.
1 For those of you who, like myself, owneither a +3 and/or 2A and sometimes wishit could be switched to a 128 machinefrom time to time, help is at hand!!!
1 For these POKEs, simply MERGE the Basicloader and add then BEFORE the RANDOMIZEUSR command, or use the Multiface.v
1 For most purposes this will leave ampleroom for your machine code programs. Infact you need'nt leave so much room, butits always better to leave extra space incase you want to amend or expand yourprogram at a later date.
1 For instance. There is a some treasure atthe bottom of a pit.Don't ask how it gotthere cause I don't know!m
1 For infinite air, add the following POKEs:*
1 For fun, try altering the second value inline 60:2
1 For example, in some copies of his lettersand magazines, he says that PD can bedistributed for any price, but cannot bealtered. THEN, he says that it can bealtered and even compiled into anotherlanguage!
1 For example, if the line 40 OUT 255,139 isused, it would be established that 255would address the control port of the PPI,and 139 would be the control word whichsets port A to output and ports B and C toinput. Then a line 50 LET a=IN 191 wouldread the inputs of port B and a line 60OUT 159,255 would output all eight datalines of port A. This now becomes a simplematter of setting up the control word andthe port address. I have also included twoBASIC listings to show how this might workwith the relevant circuitry.
1 For example, Womo are very close to AndyDavis and Miles Kinloch. For some timenow, Mr Sherwood has been trying to becomeclose friends with WoMo. How can he expectto achieve this? The loyalty of WoMo willdictate that they will never be his friendwhen he directs such attacks. If they did,I am certain that other groups and readerswould boycott their service.
1 For example, BBC2 is showing Star Trek:The Next Generation, once a week, onWednesday evenings. In the time it hastaken BBC2 to show all seven seasons, Skyhas managed to show the entire series FIVETIMES, on a daily basis, rather than oncea week. Speaking of TNG, it's now nearingthe end of it's run on both channels. The7th series isn't as good as the 5th or6th, but still came up with two classicepisodes - THE PEGASUS, which saw theEnterprise temporarily gain a cloakingdevice, and PARALLELS, which dealt withparallel realities, always a good crowdpuller.

1 Coria was looking out of the glass dome ather home planet, the sky was clear and thesun cast an amber reflection over thewater all around, in the distance shecould see the party was still going strongon the recreation island, the sun had casta reflection of the dome onto the waterand it just looked like a giant ball, halfin, half out of the water.
1 Coria was asleep when Jarus came into thecontrol room drinking his first meal intwo days so he left her to rest whilst hechecked how long it would be before theyarrived at thier destination, 'Onlyanother 37 hours to go' he said to himselfafter checking the panels. '36 hours 48minutes and 17 seconds to be precice'Coria's voice entered his mind, which madehim turn to look at her.
1 Coria lifted the male out of his bed withtelekenisis and started to move himtowards the window, she opened the windowwith another thought and began moving himoutside.
1 Coria levitated them all upstairs afterfinding that the stairs creaked when stoodupon, then went to the big room at thefront of the dwelling. Inside the roomwere two adults sharing a bed, one maleone female, Samak and Aleen came into theroom after checking the others andreported that there was an adolecentfemale in one and Aleen had seen a male ofaround four years old in the other, bothsound asleep.
1 Coria had got the man outside now and hewas floating towards the trees where thiercraft was, 'I think it would be quicker ifwe all levitated back to the crafttogether' she said as she lifted herselfand the others and started to move themtowards the trees.
1 Coria continued to control the craft asshe joined in with the others activitiesand never lost concentration no matter howdistracted she was, the rest of the crewfelt comfortable as they knew that she wasable to designate a portion of her brainto controlling the craft as easily as shebreathed, it was like the craft was partof her and she moved it as she would moveher arms or legs. Only her race could joinwith electronic devices in this way andbecome a kind of central processor forwhatever it was they controlled.
1 Coria called the others into the controlroom, 'We have just passed the planetNeptune on the edge of the solar system,so we will be in the Sun's orbit in tenminutes, i'm taking the craft up to 4.2light speed and starting the vortex, strapyourselves in'.
1 Coria brought the craft inside the planetsatmosphere above the area they had decidedon and Samak sent out the tiny probes thatwere designed to look like 20th centuryinsects, they were programmed to locateand stay with someone who had all thesymptoms of the virus then signal back tothe craft when the person was asleep.
1 Coria was sat at the helm with theelectrode band around her head thatamplified the signals from her brain tocontrol the craft, she had her eyes closedbut that did'nt worry any of the others,they knew that she would be able to sleepduring the journey to the solar system andstill manouver the craft safely, it wasonly during the time travel sequence thatshe had to be fully alert and that wouldbe in a few days. The rest of the crewdid'nt have much to do on the journeyapart from going over the mission detailsand checking that everything was where itshould be ready for the human that theywere going to pick up for the samples.
1 Coria unlocked the door without anytrouble, by thinking about it, then thefour of them entered the dwelling quietly.'There are three rooms above us withcarriers of the virus' Jarus said 'Coriaand I will check the big front room, Aleenand yourself will check the smaller roomsat the back, please be quiet and don'ttouch anything' he said turning to Samak.
1 Coria looked impressed at

1 But, the speed was beginning to be a bitof a pain. Whereas a 48,800bps modem wouldtake under a minute to send a completecopy of AlchNews to someone, on the 2400modem, it would take well over half anhour. After telephone and electricitycharges, it would be twice as cheap tosend a disk by post!

1 But multiplication is a toruous businessin machine code. There is no instructionto do it and it must be performed byshifting the binary digits about. Additionis easier, so to multiply the ASCII valueby eight, you simply double it -by addingit to itself- three times. Note that thisisn't done in the A rgister because it isbound to overflow an eight-bit register-48*8=384, the start of the character 0,is greater than 255, the maximum capacityof an eight-bit register- but it won'toverflow a 16-bit register.

In this casethere is no danger though. The low-byte ofa screen location only reaches 255 at theend of a line.

1 As they came into the suns orbit at justabove 75,000 miles above it's surface,Coria took the speed up to 5.3 light speedand signalled to Samak to start the timetravel sequence, instantly his hands werepressing buttons, turning dials andflipping switches.

However, you are restricted to 70mph on our roads, down to 20 mph in someareas.

Theaddress chips could be soldered directlyon to the board, but the 8255 will need tobe socketed. Take care when pushing thischip into it's socket as any number ofit's 40 pins could be broken.

1 A pointer is a memory location, or rathera pair of memory locAtions, which storesthe address of another location, in thiscase the start of a particular section ofmemory. The address of any byte of memoryis two bytes long, so it has to be storedin two adjacent memory locations.

1 A 48K spectrum has 64K of memory space intotal. The 'K' figure refers to the amountof memory you can use, the other 16K isreserved for the machine's use.
1 A 'K' in computing is roughly analogous tothe 'k' which stands for a kilo - athousand - in the metric system. But 1,000is not very convenient when converted intobinary or hex.
1 A professor by trade, John had beenworking on quantum acceleration theory forseveral years and had always had a firmbelief in time travel. It was only nowthat his dreams were at the stage offulfilment. To the incredulity and scornof the world's physicians, he had arrangeda public meeting to demonstrate, for thefirst time, the concept of physical timetravel, in an experiment described by thepress as being years ahead of its time.

1 9. The program structure is similar to theexample given above, but the CLEAR andRANDOMIZE USR numbers are zeros. Because afive byte qualifier is stored after allnumbers in a program (this is why VALssave memory), it is possible to make anumber look like a zero but be somethingelse. Edit the line (avoiding the zeroitself) and when reentered, it shouldassume the correct value. This appliesespecially to Betterbytes software.

1 6) FILE SWAPPING (2). If you are regularlyusing a +D disk on the emulator, you mayfind it to be rather slow. The trick is tocreate a new directory (In PC-DOS) andthen load the +D utility TRANSIT. Selectthe disk-tape copy option and ensure thatTAP direction is at this new directorywhich you have created. After transfer,you can then access all the files as TAPformats, far faster from your hard drive.

'Were all alittle frightened' Aleen cosoled her 'butwe have to do this for the sake ofsurvival'. They both stood in silenceafter that, pondering over the journeyahead whilst taking a long last look attheir planet before they were called tothier positions on the craft.

Mycollegues and I would like to assure youthat we will be back in a weeks time withthe immune system that we need to survive.I also know that there are a few peoplewho are against the idea of tampering withthe past, but let me assure them that wewill not disturb or corrupt our own time,this mission is going to be as discreet aspossible and we do not intend to harm anyof our ancestors'. The place erupted incheers as Coria brought him back down toher side, 'Short, but to the point' shesaid as his feet touched the platform.
1 'What we are seeing is the colony of NewAmerica on the southern hemisphere, peoplehave started dying from a disease that wasbrought back to this planet from oldmother earth by a quantam physicist whohad travelled back in time to study ourancestors.
1 'There it is!' Aleen said, pointing to asmall furry creature sitting on top of awall, 'It's a decendant of the Africanwild cat, Felis lybica, otherwise known asa domestic cat kept as a pet. They diedout after being brought to our planet'.
1 'Thanks a lot for that!' he said to therest of the team, who just laughed atseeing how flustered he was, he laughedalong with them as he brought a drink tohis lips and downed it in one.
1 'So if we took this one back, it would dietoo?' Samak asked. 'It could die, but itmay pass on another virus to us, so wewould'nt be able to take it with usanyway!' Jarus interupted before Aleencould answer, 'Come on, it's this dwellingwe're looking for' he said as heapproached the door, reaching to open it.
1 'No wait!' said Aleen urgently, 'In theyear 1995 people protected thier propertyagainst intruders with electronic devicesthat they called alarms'.
1 'No point in staying awake if there'snothing to do is there!' he said as hestood up from his seat, 'I can go over themission during stasis and get everythingready a day before we come into the solarsystem'.
1 'It seems like we have found a family thatall have the virus' Jarus smiled, 'I'llcall the probes back to the craft when weland' Samak said.
1 'I'm sorry I did'nt realise that I wasthinking openly' Coria said, 'I was justwondering if we'll see our planet again,we might not even make it out of the sunsorbit properly and go crashing intoanother planet', Aleen looked at her,'Don't tell me your getting cold feet now,15 minutes before take off. You werechosen from over 600 people to pilot thecraft because you were the only one thathad the reactions to pull off the requiredmovements, apart from Borok no one elsehas the slightest chance of getting usthrough it, and he's dead!'.
