Thething we all had in common was ourinterest in the above areas.
1 You would also have to write thedecompressor as a seperate program or evenbuild the two programs into one. Using the128K ramdisc as a buffer area, you shouldbe able to make the process even faster byusing the extra 80K of RAM to read in 1/10of the source disk.

The Amiga has akey with the "A" logo on it. <TheCommodore's all had silly 'C' logo keyswhich did very little. You never saw a'rainbow' key on the Spectrum, did you?Ed.> And now the latest PC keyboardsfeature nothing less than a Windows '95key! The whole point of screen icons is toperform functions too complex to merit akey.

But, as ever, he comesup with the goods, which are always betterthan we expect. In fact, I have a smallarchive of revolutionary programs byDominic, including some wonderful newshells for AlchNews.
1 Whether or not he had the "right to selfdefence", Mr Sherwood certainly did nothave the right to distribute any part ofAlchNews, which was and is Andy'scopyright. To conclude, the considerableamount of evidence that Mr Sherwood hasbeen an illegal software distributorprevents me from publishing an apology atthis time.
1 Whenever you write an article about theSam, please send it to me. Articles aboutthe Spectrum may be sent to Andy or me.Andy tends to publish them just as theyare, but if you don't mind (or evenprefer) mistakes to be corrected, sendthem to me. I'll always correct them insuch a way that the readers won't evenknow that they have been corrected, sodon't worry

1 When you first run the program, you willhave to wait for a short time while thecode is poked into memory (starting ataddress 43000). Make sure that you type inall of the numbers correctly as a singlemistake could prevent the routine fromworking!
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 come to write a Pascal program,this means that you must work within aprecisely defined form for each statement.These standard definitions are given in aformal notation developed during the 1960sand know as Backus Naur form (BNF). Theycan also be given as syntax diagrams.
1 When the program thinks it has located thefirst password (ie the first two lettersmatch those of the password), it leavesthe scanning loop and prints the entirerest of memory to the screen. Hopefully,the passwords will now appear insuccession for you to write them down.

1 What do we change? Well, thats entirely upto you. The first places to go are thenasty bugs in the Spectrum. There areliterally dozens. A few can be easilycured by one simple value change, othersare more complex. Ferry Groothedde haswritten a custom ROM which eliminatesEvery bug, and also added new commands,but this consists of a major rewrite ofcertain areas, which are beyond theconfines of this basic introduction.
1 What you change the keywords to iscompletely up to you, but here are somesuggestions to get you started:s

1 We have been ZX enthusiasts since 1982 andhope to improve and expand FPD with eachnew catalogue. Thank you for your custom.}
1 We finally found it as the light wasdimming and my patience wearing. The nextsurprise sprung on me was that Martin andDave weren't talking and I had to go andfetch the disk. A disk of which I had noidea what was on it, from a person I hadnever spoken to in my life. It wasactually Simon 'Spec Tec' Cooke, who metme, who looks NOTHING like his charicaturein YS.
1 We established that the reliability of theghost was due entirely to whether therehad been any previous rain, which ran intothe dip and made a tiny stream whichfilled the puddle, the speed and positionof your car on the road and, mostimportantly, what car you were using.Headlamp alignment is different on allcars, as is the shape. I had tried it onboth my Minis and my Metro and there wasnothing. Ford had a Fiat Panda, which gavethe best effect!
1 We end with a new magazine, aimed directlyat ZX81 users.8
1 We end with the ZAP utility which canperform block file deletes from acartridge. The program also comes withZAPMOD and ZAPMOD2, two merge-in routinesto give extra functions, such as bytesfree.
1 We do this by loading up the PD program TASDFUE. Load it up and you will be presented with a menu.j
1 We change the ROM by quite simply loadingthe ROM area to RAM, where we can alterit. There are two ways of doing this:y
1 We can MOVE (or copy) any PATTERNS CHANNELdata to any other. In the followingexample we will MOVE PATTERN 1 CHANNEL Ato PATTERN 2 CHANNEL B.
1 We at this new software house understandthis. That's why our first release willjust be a plain collection of high quality'mini' colour graphics.
1 We are now going to create a simple tune.First let's get rid of the tune in memory,it'll only confuse things. Go to the OTHERmenu and select CLEAR PATTERN. You will beasked to confirm. Now select CLEARPOSITION. Finally select RETURN and off wego.

1 Version 4a (released around 14th Jan '96)Simply version 4 with a few extra thingsI've added. (Supplied with AlchNews 19 +D)~
1 Version 4 (released early Jan '96) MilesKinloch has modified SNAP READER so thatit now uses the +D RAM as a buffer,solving the problem of screen corruption.Also, now the games that crashed if thescreen was corrupt (i.e. MERCENARY) willnow work fine. Unavoidably, SNAP READER isnow incompatible with Beta-DOS and some +Dpatches
1 Version 3 (released around 5th December'95) When I contacted Andy Davis and toldhim about SNAP READER he asked me to sendit to him, and he'd pass it on to MilesKinloch (THE +D programmer). So I bunged afew extras onto version 1 (Instructions,re-cat, speeded it up etc) and sent it toAndy.
1 Version 2 (never released) This was myattempt to get SNAP READER to use the +DRAM as a buffer instead, unfortunately Iknew next to nothing about the +D'sinternal operations so it had a tendencyto crash.
1 Version 1 (release date unknown, authorunknown) was given to me around June 95 Itused the screen display as a buffer and socaused partial screen disruption and alsocaused some programs to crash. <Featuredas a listing in an earlier article in thisissue. Ed>

1 This will play each PATTERN in turn. Don'tforget to set the LENGTH to more than 1otherwise on PLAY, the ST will only letyou hear the first PATTERN over and over.
1 This was the big problem until I decidedthat Andy Davis was reliable enough to dothe job. The SCB (Sinclair ComputerclubBenelux) has been renamed AlchemistResearch Continental, and our jointmagazine has a double name. AN/UC&USfeatures both the Spectrum and the Sam.
1 This was absolutely great! 'Up', 'Down','Up', 'Down'. The man moved to my everyword! He even moved to other words.'Sausage'. 'Tootle'. 'Supercalifragilisticetc. etc.'. I spoke, he dodged. Sometimeshe jumped INTO the path of a car!
1 This view shows the rear of the aircraft,along with display of remaining rounds ofammunition and status box of otherscreens.
1 This type of loop is usually used when insome circumstances the loop is not changedat all and the number of repetitions isnot known beforehand. The repetition willcontinue once each time a known conditionspecified in the program remains true.
1 This trick can be performed by all andthere is no chance of damage to equipmentif the guidelines are followed correctly.I have used this trick for over 15 yearsand in all that time have neverencountered problems. However, AlchemistResearch does not take responsibility forany poor attempts which fail or fail towork, or video recorder damamge.
1 This takes the ABCD membership to wellover 50! If you'd like to recommend anyonefor an ABCD award, write and let us know.}
1 This simply selects which drive is to beused by SNAP READER (the current drive isdisplayed on screen). Thanks go to MilesKinloch by the way, for pointing out thatthis didn't originally work, and forfixing it.
1 This should return 65535 on a 48K model. If it doesn't and you haven't POKEdanything into these locations then thereis something wrong with your spectrum'smemory.
1 This short and simple program gives briefsystem details of the Spectrum, such asRAMTOP, free memory, length of microdrivemaps in memory, free space etc.
1 This routine makes the player lose a lifeand then loops back to the game until hislives are used up. Fine as it is, but ifwe replaced the number 3 with PI, thedecimal places would mess things up. Thisis what you'd see:
1 This program performs the same function asthe routines earlier, but is for users ofany Multiface who do not have a +D.w
1 This program is revolutionary. It is fartoo good to be given away for peanuts. Itis only fair that Dominic be given fullcredit and reward for his hard work.
1 This program is only really useful for afull cartridge of programs you are goingto keep. You store the program's filenameand some brief details in a string andthen save the program as an auto-bootfile. It is similar in principle to AndyDavis's DLS system.
1 This program is for the Interface 1 or +Dand, like Multibasic, adds some simplecommands to treat the Multiface memory asan 8k ramdisk.
1 This program gives full details of allfiles on your cartridges. It is colourfuland well presented.g
1 This particular example is no use at all,since VAL "2^5" is longer than VAL "64" byone byte. The good thing is that powersallow huge numbers to be expressed insmall terms. In addition, powers of 2(where the a in a^b is equal to 2) areuseful numbers for programming with, dueto the computer's binary system (base 2).Some examples? No problem...
1 This option is simply here so you cancheck if a disc you've put in the drive isa +D one or not. If you try this optionand it is not a +D disc then the Spectrummay keep trying to access the +D'sdirectory data. If this occurs, simplyinsert a +D formatted disc and it will becatalogued.
1 This joins the two files together (the xxbeing whatever the current issue is). Thisprocess is repeated for all the seperatefiles. I start with the loader (afteraltering it to run from line 300),followed by the two pieces of code for themusic (ANxxC & ANxxD). I then use thefollowing lines to speed up the process.
1 This issue of AlchNews had no less than133 parts, making over TWO MEGABYTES ofdata! However, it is no longer tape or +3disks which limit the magazine, but the 80file capacity of +D disks! So, all futureissues will have a ceiling of 75 parts.
1 This is where the patience comes in:$
1 This is the memory which is open to theuser, but is not quite as wide open as itsname implies. The ROM takes over some ofit for screen displays and other specificfunctions and if you try to writesomething in these memory locations theROM will change it back for you. Butfundamentally it is an empty slate onwhich you can write whatever you want,then read back at your leisure.
1 This is the engine which will give theutility its ability to store those +Dsectors in smaller amounts of storagespace than it actually takes up on disk.
1 This is more of a simple routine than aprogram. It disables the Multiface menu,so you get the full 8K of RAM available toyou.
1 This is more of a list than an article - Icompiled it after scanning through BetaDOSfor all the +D resident messages. Thefirst list contains only error reports;the second contains all the othermessages. The network errors were used bythe Disciple system but are redundant asfar as the +D is concerned.
1 This is the main option, the one theprogram was written for. To use it, insertthe PC disc containing the .SNA files thenon the menu press 'C' (or 'SPACE' ). Thedisc will then be catalogued.
1 This is the cockpit. It is from thisscreen that you actually fly the aircraft.Here you make sure you don't go too highor too low, too fast or too slow.
1 This has not been tested on an emulatorwith TAP files - use at your own risk!P
1 This file can now be accessed from theEmulator. Using the TAPE menu (F7), selectthe magazine file from your hard-drive. Ifyou are in 128K mode then you can changethe music by MERGEing the program andaltering the line which loads in 'ANxxC'and change it to 'ANxxD'.
1 This example should be simple to follow,and you might like to try writing healgorithm on which it is based.s
1 This can be determined by holding the tapenear a light source. If you see creases ormarks of ANY kind on the main part of thetape, it should be discarded. If the edgeis rough or creased in any way, thatshould also be discarded, since the videorecorder records the picture on the centreof the tape and the sound on the edges.
1 This article may be utterly pointless andwholly inaccurate, but it nonethelesscontains a completely original idea,guaranteed to generate new interest in theSpectrum.
1 This article comes as a follow-up to myprevious one on the same theme. The aim ofthese tips is to decrease the amount ofmemory used by your BASIC programs, inseveral ways.
1 This approach did indeed work, though, Ihad to modify the circuit and fit adisable switch till the game was up andrunning as the base unit checks the ROMfor errors - there appears to be achecklist at the end of the first 32Kblock of the ROM which it uses as areference, though I have not as yetfigured it all out ... if the checksumdoes not tally with the ROM then the gameis not entered and the message 'Softwareerror' appears on the screen and nothingelse happens until the machine is switchedoff and re-booted with another game.
1 This CD really uses the potential of this medium. It contains about 3000 Spectrum program snapshots, lots of pictures of Spectrum
1 This program does a catalogue to thescreen and then places a menu bar there.Using the cursor keys, you can select afile of your choice and press ENTER toload it.
1 This doesn't mean that you have tounderstand how the chips are etched or howthey are wired up. But you do have to knowa little of the overall architecture ofthe machine, How the major parts andsystems are related and what each onedoes.

1 These can all be replaced with NOT PI andSGN PI, of course, to save bytes, but ifany number crops up particularly often,it's worth allocating it to a variable. Ialways use the variables O and I torepresent 0 and 1 when writing BASICprograms of a considerable length. Let'srewrite our lives routine in a moreefficient way:
1 There were various reports of sightingsand lack of them. Usually, in a case likethis there may be some natural phenomenonto blame to the apparition. Our team didextensive work but found nothing.
1 There is another suite, called 'Run', butit's in German and won't run properly, sowe'll leave it out!g
1 There is also Version 2.0b available but Ihave been informed that there is littledifference to 2.0. to warrant upgrading.|
1 There are two ways of removing the badtape from the cassette. The first methodis to fast forward the tape from thebeginning to a part where you know it isgood.
1 There are two private sellers of a numberof Microdrive cartridges. Check eachseller for price.e
1 There are two different types of memory -ROM and RAM. ROM stands for Read-OnlyMemory. That means you can read out of ROMmemory locations, but you cannot writeinto them. 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.
1 There are some things which are lacking though. The nature of taking game snaphots\
1 There are four possible viewpoints on yourAvenger bomber. To move from screen toscreen press the appropriate key on yourkeyboard. Each screen will be described indetail in the following sections.

1 There are currently two versions of theprogram available. The first, and originalis the one you get here. The second is thesame as the first, but has had visualimprovement by EWGF on 8/12/95. Thisupdate has machine code and a font storedin REM statements, so cannot be listed.The program features details on theprogram, plus addresses of AlchemistResearch and Mike Mee. A third version iscurrently being made.
1 There are a number of emulators availablefor the Spectrum. The most popular is Z80,by Gerton Lunter. There are numerousreviews on the system so I will not dwellon it. But, there are two other popularones; JPP by Arnt Gulbrandsen (Norway) andSPECTRUM by Pedro Gimeno (Spain). Allthree each employ different techniques insaving games in snapshot format (nothingon the Spectrum is simple!).
1 There are a lot of bargains out there, itjust depends where to look. I've beeninformed of some services charging wellover the odds for some consumables, it'sjust not on.
1 There are a couple of examples to provethis. The first program gets the computerto print five random numbers:q
1 There are 6 spaces between the quotessigns in line 6.:
1 There have been a couple of programsavailable for some time which allow usersto access double density PC disks andextract text files from them. Now there isa simple BASIC program which allows you toview and load games from a PC disk, whichhave been saved as a 'snapshot', similarto the +D's.
1 There are two main classes of RS-232devices, namely DTE (Data TerminalEquipment), such as terminals, and DCE(Data Terminal Equipment), such as modems.Typically, one only interfaces a DTE to aDCE, as opposed to one DTE to another DTE,or one DCE to another DCE, although thereare ways to do the latter two by buildingnon-standard cables. Rarely if ever aremore than two devices involved in a giveninterface (Multidrop is not supported). Aserial port on a computer may beimplemented as either DTE or DCE,depending on what type of device it isintended to support. The Spectrum 128k isconsidered a DCE.
1 There are still two great lists ofhardware, software and books doing therounds. Should you want one, send an SAEto:
1 Then, as I read the magazine, I noticedsome Emulator based articles from Andy andsomeone else whose name escapes me rightnow.
1 Then, Dave changed his mind and decided toget the bus, so I took him to Manchester.Tired, exhausted, badly in need of somemedicine, we turned and drove up a wrongway street, down several bus lanes andblank endings, tram routes, Moss Side, andmuch more. We gave up trying to find thebus station so I threw him out atPicadilly.
1 Then the character on screen, say "*", isstored twice:7
1 Then appeared 1.6 which had improvedconsiderably. Next was 1.7 (or 1.6b) Therewere 2 versions of this, one for the A500and one for the A1200. The earlierversions were meant for the A500 but werereally too slow to be any use, unless youenjoy making cups of tea in between keypresses!
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 version I'm going to talk about is forthe A1200, the AGA version.E
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. 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 usual disclaimer rules apply; NeitherI, nor Miles Kinloch, Andy Davis,Alchemist News, whomever you received thisprogram off (or the .SNA files) etc can beheld in any way responsible for anyloss/damage caused in any way by the useof the program or whatever.
1 The uses are endless. You could begin byenhancing Kevin's original program to givea more detailed display of how a word iscomposed, and perhaps create yourself alittle database of words, so you canquickly add them to a program.

1 The system variables are the locationswhich hold the addresses, or pointers, ofthe beginnings of the specific areas abovethem in memory.
1 The square in the top half of the screenis where individual characters are workedon. The following is a brief descriptionof the icons.
1 The solution to Andy's problem lies withthe COPY command.;
1 The services and contacts here are allin regular communication with AlchemistResearch and are considered reliable andtrustworthy.
1 The second problem (the file format) ismore complicated. An emulator is just aprogram that simulates a computer (so aSpectrum emulator running on a PC is justa program that makes the PC 'behave' likea Spectrum. The problem is that there area variety of Spectrum emulators availablefor various machines and since there wasnever a standard snapshot for the Spectrum(apart from the +D there was theMULTIFACE, the MIRAGE MICRODRIVER, theSWIFTDISC, the Beta Disc etc) and sorather than base their emulators' snapshotformat on any of these (which wouldn'thave been necessary anyway, since the discformat was so different) the emulators'authors tended to develop their ownsnapshot formats. As far as I can see theclosest to a standard seems to be the .SNAformat which SNAP READER reads.
1 The routine is fairly simple and as suchit splits up the screen into just foursquare quarters (see details below), eachof which is a different "touch registeringarea". However, the touch screen isnonetheless a fascinating addition to anyprogram. When touching the screen, makesure that your finger is firmly againstthe screen and hold it there until itregisters with the computer.
1 The result should be 127...
1 The reason for turning the printer portoff is simple; some games/programs crashif the port is active (at present I knowof three: CITY SLICKER, RED MOON and LORDSOF MIDNIGHT). This problem occurs whetherthe program is loaded from cassette, +Ddisc, PC disc or whatever. So if you everget a program (be it on tape or disc) thatcrashes when loaded try it with theprinter port turned off. To turn the portoff from BASIC type:
1 The real programming will be small. Why?Well, do you really want menus beyondbelief or would you prefer your 48kcrammed full of graphics instead whichwill be what you want to pay your cashfor?
1 The quad two input nor gates were wired tothe ROM, the 1st CD4040, the Spectrum, thetwo 365s and itself as follows:s
1 The program works by first cataloguing thePC disk. It does this by loading thesectors of the catalogue track into memory(32768-37138). A short routine thendisplays the files and allocates a numberto each.
1 The program works by adding new commandsto Basic. All disk access to and from theexternal drive is to a +D disk. So, it'slike you only have the basic +3 withinternal drive. But, you have a +Dattached, which is far more versatile than+3DOS.
1 The program worked by paging in a RAM pageinto a normally ROM resident area. Theresult was a little bit slower, but wasPOKEable. It also helped a number of gamesto run better on the +3, which hadterrible compatability problems with somegames.
1 The program is very simple. Enter the source drive number (0), the filename, the drive number for the converted file (0 again) and then the converted filename, TEST3. With the emulator, the conversion will take only a second.
1 The program for the Spectrum will loadonly the SNA format, which also happens tobe used by the Spectrum emulator runningon the Amiga.
1 The program allows you to store up to 8kof a Basic program / screen picture /machine code in the Multiface, recalled bysimply pressing the button. The advantageof this program is that no machine codeknowledge is necessary, just a simpleRANDOMIZE USR does all the work for you.
1 The procedure behind the theory of a diskcompressor is as follows:C
1 The printer buffer holds the next line oftext that is going to be fed out to theprinter.\
1 The price for the full version? A paltry`6. And worth every penny. However, if youhave registered a program with Dominicbefore, such as with SLOWDOS, the price isjust `4. Being registered, you then getfree updates and revisions, and a freecopy of all Dominic's programs.
1 The pointers are so called because, whenthe computer looks at them, it is directedto the location it should move to.v
1 The plan was to wire the 9-way D socket tothe cable (for the PC) and the 6 way stufffor the +2. Because of the messy joinbetween the two, and the trial and errorof which wire goes to which, I decided tomount a terminal block inside the box. Icould then swap and change each wire if Ineeded to.
1 The other programs supplied are a tad moreserious. They allow you to speak into thedevice and get an analysis of how thecomputer interprets what you say. Thisallows you to speak certain words andget details of how the computer recognisesthem - allowing you to add your owncommands in a game. Imagine modifyingthe Tasword main menu and speaking 'PRINT'to start it printing!
1 The only real way to do this on a singledrive system, would be to read x amount oftracks in 1 go, compress the whole lot andthen swap the source and destination disksaround and write the compressed block tothe destination disk. Then ask the user tore-insert the source disk. Painful but anecessity to enable all +D owners to usethis package.
1 The officer paid a visit to Mr Sherwood,to get further information on hiscomplaint, where it was found that Prismonly had approximately "20 to 25 members",says Charles Nickson, of the DataProtection Registrar!
1 The obvious benefits of this program wouldbe to store a help screen or any screenresident utilities, such as UTILS1 or anyof the packer routines available.
1 The numbers 0 and 1 are used very much inBASIC programs. You'llD
1 The next step was getting the data in theACTION FIGHTER ROM into the RAM of mySpectrum, so as to find a hack forinfinite time. This was achieved byconstructing a circuit on Vero board using2 x CD4040 binary counters, 2 x 74LS365quad hex tri state buffers, 1 x 74LS502quad two input nor gates and 1 x twenty-eight pin IC socket for the ROM.
1 The next step is to configure the touchscreen for your monitor. A red square willappear on the screen which you will beasked to touch. When the program hasconfigured the code to suit your monitor(although the chances are that it willalso work on most other Spectrumcompatible monitors), it will stop withthe message "Touch screen code is inplace".
1 The next project in the pipeline for thismachine is to completely extract the tapemechanism, fibre glass over the tape deckdoor, spray it black and add some +2akeys. I will then be re-siting the I/Osocket in it's place so that the +Ddoesn't stick out attracting dust.
1 The names of any masks portrayed in thisstory and their relation to any persons,alive or dead, is purely co-incidental.{
1 The most common problem with video tapesis their length. The most common tapelength is three hours (E180), but in mostcases, the entire tape is rarely used.
1 The middle third is the PATTERN editor, itshows the three sound channels, A, B andC. This part seems to cause the mostterror but it looks much more complicatedthan it actually is. The important partsare the first three values of every lineon each channel. The first value isactually a NOTE of music, C, F#, G etc.The second value is the current OCTAVE andthe third is what SAMPLE is being used.The remaining three possible values foreach entry are used to shape the sound butwe need not concern ourselves over theseyet. You can create excellent soundingtunes without those last three values. Thebottom area of the screen is a graphicequalizer; it can be seen as either apretty light show or an invaluable guideto bass and treble balance (but only ifyou are a dull old muso).
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 matter was closed. Alchemist Researchdoes NOT need to be registered and we areallowed to store names and addresses onthe computer if we wish, and are allowedto create and edit our articles on ourcomputers.
1 The main screen is split into three; thetop third contains the menu, the choicesbeing activated with a cursor:r
1 The magic ingredient missing from thisuseful piece program is the codecompressor._
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 letter R can be entered to signify aREST. If you wish to delete an entry thenpress ENTER.`
1 The latter can also supply a variety oflegal snapshots of games, including anauthorised collection of over 30 GremlinGraphics games. The collection is suppliedon two PC disks and costs `1.50, allinclusive.
1 The last two bytes 225 and 0 are NOT theend of the variables area! 225 is theFOR/NEXT variable A, followed by itspresent value, the end value (after TO),the STEP value, and finally the line andstatement where it has been set up; 19bytes in total. The real end of thevariables area is a byte holding 128.
1 The interview was great, very informal andrelaxed and generally a tape version ofRoy's Rantings! I showed Matt and Davesome examples of Prism problems (Prism's,not mine!), and Matt explained that he WASjustified in being featured on the Hall ofShame and had no problem with his namebeing listed. Dave was the same, which isnot surprising, since we have workedtogether for many years and I know that acertain someones claims were wrong. Davealso informed me about Prism illegallyselling some ARCADIA disks as PD when theywere not, which reminded me of similarproblems with programs written by AndyDavis, Theo Develegas, Miles Kinloch, TheUnited Minds, Chris Taylor (need I go on?This is all very boring.).
1 The interesting thing was that there arethree lanes all in the close vicinitywhich give off these strange effects. One,which worked very well in the Mini, wasstraight and flat but with some gentledips, and gave a UFO effect, with threesaucer shaped discs in the sky in front ofyou. Even now as we know the reason forthese effects, they still amaze us andfrighten us a little as we pass!
1 The instructions gave clear and concisedetails on how to connect it. Presentedwith such a tool, the usual method wouldbe to just 'bang it in' and then panicwhen it didn't work. Although theinstructions were standard of how youwould connect an interfaced device, theyshould still be read.
1 The instructions are well detailed and,after some practice, the game can beeasily mastered. The game runs at animpressive speed on both Spectrums andemulators.
1 The important difference between the threeforms is the control condition thataffects the number of repetitions. In theWHILE .. DO, repetition continues while aknown condition holds true. In the REPEAT.. UNTIL it goes on until a conditionoccurs. These techniques are used when thenumber of repeats is not known beforehand.Where it is known, or standard SpectrumBasic users, FOR .. NEXT is oftenpreferred, getting around conditions withsuitable IFs, ANDs and THENs. Messy, butessential.
1 The full version also boasts these extrafunctions, which you would find asstandard on the +D, and some which younever would:
1 The following routine was written in 1984by Mr F Lipar of Somerset, who has kindlypermitted its reproduction in AlchNews.Using only a short piece of code, createdby a BASIC program, you will be able tohave a touch screen which works onvirtually every type of monitor with noadditional hardware required.
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 defines the UDG andthen displays a simple bar to show theeffect. It is quite simple to adapt thecolour to any you desire.
1 The following is a description of eachCockpit control - along with informationon how to use these dials in flight ancombat.
1 The following commands will now give youinformation about the touch screen. Ineach case, use LET A=USR q
1 The following article is a collection ofSpectrum record breakers, inspired by asimilar piece in Sinclair Classic. I hopethey don't mind 'cos I nicked some oftheir ideas! All games mentioned arecommercial releases, so Roy Benson'slawnmower game with its paragraph-longtitle sadly fails to qualify!
1 The first step is to get a copy of themachine code. If the game has a verysimple BASIC loader, this should be easy.However, protected games will need to behacked - something which I can't helpwith. Try your local hacker!
1 The first problem (the disc format) isbecause there is no standard disc format;most computers store information on discsin their own way. That's why you can'tread (for example) an Atari ST disc on a+D. This explains why when you first use adisc you first have to format a disc; thislets the computer organise the disc'sstructure to it's own method of storage.The closest thing to a disc formatstandard is the PC/MS-DOS Double Densityformat, which is the one SNAP READER uses.These different disc formats, by the way,all use the same 3.5" discs. You can'ttell (of course) how a disc is formattedjust by looking at it, they're allphysically the same.
1 The first part of this series on Pascalshowed how you need to work out thesolution to a problem before you start toprogram the computer. And you need torefine your solution until it approximatesto a Pascal program that can be given interms that your computer will be able tounderstand.
1 The first issue is a simple 8 page, A5affair, but despite hailing from Germany,is in English - excellent English at that.~
1 The firm CPC which stocks spares for theSpectrum sells a box of ten NEW Amsoftdisks for `18.99 + VAT. For more details,contact:
1 The final trick up a BASIC programmer'sproverbial sleeve is that of mathematicalpowers. As anybody with an inkling ofarithmetic will know, the ^ sign (on theSpectrum's H key) denotes raising to apower. For example, a^b means "amultiplied by itself b times", so:
1 The file format of the +D compressed diskshould ideally contain some checksum orother form of failsafe routine to ensurethe data being written back to the +D diskis as it was when it was compressed.
1 The faster version doesn't crash out asmuch, but the music is sometimes slowerthan the complet e version.o
1 The emulator runs certain games perfectly,PHEENIX and JETPAC come to mind. However,games like GHOSTS ' N' GOBLINS, just crashwhen you get to the beginning. If you hadan accelerator I suppose it would workokay, because I copied G'N'G to try it ona friends PC emulator <Mine. Ed.> and itworked fine, so it must be the computer.RENEGADE will work fine but runs about twothirds the proper speed, so I sometimesfall asleep while walking from one screento the next.
1 The emulator is a fine program. A littletoo fine in some cases. Listing a programto a printer can sometimes be an awfulpain. If you are emulating a +D in 128kmode, you have to make sure that you arenot printing via the 128k RS232 port. Youthen may have to mess around with thePOKE@6 address depending on how your DOSis set up, and so on.
1 The display area controls what is shown onyour TV screen. Each memory locationcorresponds to a line of eight pixels.z
1 The demo song within ST is made up ofSAMPLES. ST can store up to 15 SAMPLES andeach one is selected to be the currentSAMPLE by the increment/decrement arrowsto the right of the SAMPLE option box. Thefollowing is a brief description of whattype of sounds are included:
1 The data you see in the EDIT channelswindow is translated thus:D
1 The data was worked out by drawing asimple 8 * 8 grid on paper and filling inthe colours. Each block filled denotes a 1in binary, or 0 if empty. PRINT BIN willgive the decimal figure of the line.
1 The computer uses IN 191 to read themicrophone and works in BASIC. There arethree values used to determine thecharacteristics of a word.

1 The cheapest place for blank disks iscurrently ESCOM. Prices are approximately`1.86 for a box of ten.k
1 The best way to learn the ins and outs ofthe Sound Tracker is to load in files thatare available from all good PD libraries.This will give you the chance to saveindividual sounds that take your fancy andto study what is on each channel, how itis linked together and what makes a 'good'tune. Also, check out PD demos; alot ofcoders swear by the Sound Tracker!

1 The SOUNDTRACKER is the most widely usedmusic creation utility amoungst PD coders;an official instruction manual was neverpublished and so it has been passed overby many potential users. Hopefully thisbeginners guide (and the ADVANCED guide)will make things a bit clearer and willencourage use and experimentation withthis excellent 128k music utility.
1 The SNAPREAD programs can be ordered fromthe following sources:@
1 The SIXTH line adds a black trail tofinish off.5
1 The SECOND line prints the RED part of thestripe. The CHR$ 144 relates to graphiccharacter A. This method is usually betterthan pressing GRAPH then A, because itappears correct on a printed listing andyou are not having to guess what characteris what, or have to explain that GRAPHmust be pressed first. It's all down totidy programming. Most amateur magazinesdon't think of this and it looks verymessy and unprofessional.
1 The SCREEN$ bug (cured in the SCS ROM ofcourse, and not at all present in the SamROM) is the simple fact that the result isstored twice. So if we start with an emptycalculator stack, this is what happens:

1 The Rantings!
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 PFN system comes with a full 20k Basicexplanation program. The system contains10 PFN fonts ready to use.n
1 The PFN EDITOR allows you to create a newfont for the PFN system orN
1 The PC, however, can go one step better.Although when you boot up the emulator,the ROM is fixed and cannot be poked, norcan you shuffle the pages around like onthe +2a or +3 (it emulates a black 128k),but it does allow you to load in a 16kROM file in the setup 'INI' file.
1 The Multiface suite is available from ASWand FPD, with a 50p royalty going toMiles. Other 'services' do sell thisprogram, but ask yourself this: wherewould YOU prefer to get it from! Milesregularly supplies offical updates andrevisions to ASW, FPD, IPD, MDL only!
1 The INTERNET holds (reportedly) severalthousand of them.;
1 The INT function rounds any number to itsnearest integer. This means that INT PI isequal to 3. Let's look at the memorysaving over VAL "3".
1 The IN A, (F7) performs two functions - Itenables the ROM and tri-state buffers andincrements the address counter once theinstruction has been executed.
1 The GOSUB stack stores the number of theline the computer has to return to when ithas completed the subroutine.q
1 The FOURTH line prints the GREEN stripe.(
1 The FIRST line gives a 'leader' of blackup to the first stripe.A
1 The FIFTH line prints the CYAN stripe.&

1 The CD4040's were wired as a 16 bit binarycounter, Q12 of the first connected to theclock input of the second and, in turn,Q5 of the second was wired to the reset ofboth ICs, which was grounded by a 10Kresistor.
1 The CD4040 is negative edge triggered sopin 10 of the first counter will be highwhen the ROM and tri-state buffers areenabled and will only be clocked after thedata has been read from the ROM.
1 The CD does provide some ways around this though. For example providing virtual tapes which act like the genuine tape and can be accessed when needed. There is a lack in Public Domain software and most of the demos are very old dating from between 1989 and 1991. Some of the demos contain some 'adult' content, such as the RTL series which is included.
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 /B parameter is a necessity whichallows the COPY command to join binaryfiles together, otherwise it will assumethe files are ASCII and the end resultwhich probably crash the emulator.
1 The 'club' consists of:
1 The useful advantage of this routine means that you don't have to put your code in the Multiface, it can be used as a general relocation tool. Eg, moving BASIC to high RAM while you load in another program to, perhaps, examine something.

1 The reason is because some emulatorsemulate the issue 2 keyboard of theSpectrum. However, this can be avoidedwith help of the Z80 emulator. This canemulate issue 2 keyboards and it ispossible, with just the aid of onekeypress, to change issue 2 emulation toissue 3. The modified games can then besaved as a Z80 snapshot, for conversion ofSNA format.
1 The program is an excellent one. TheGerman text is a bit off-putting, but itis easy to follow and modify.q
1 The program became confused when thecatalogue spilled over the 'Scroll?'command, as there were more than 21 fileson my cartridge.

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 Microdrive utilties collection isavailable on tape or +D disk from ASW andFPD.X
1 The Atari one is called Magic ShadowArchiver, and if you use the very firstone released (v1.41) you can compress +Ddisks into files on your Atari and storethem on a hard-drive as backups !
1 The +D version uses the MF_MAXIRAM routine to protect the contents of the Multiface, in case you reset the machine and re-enable the Multiface by pressing the button. Sadly, this also means that the full 8k of memory is not available.
1 The 'box' consisted of a black box,narrower, but fatter and taller than aMultiface. It had the usual I/O plug atthe bottom, and a socket at the side forthe microphone, and a big green LED on thetop. The box was strong and secure, andhad some solution on the screws to preventprying eyes and screwdrivers!
1 The first mock-up issue has beencirculating for a while now, and by thetime you read this, Issue 1 should beready. The price is 40p or you can order a3 issue sub. for `1.20, which will meanthat any future increases are ignored.

1 So, on the 15th February, Mr Nickson paida visit to Alchemist Research. Heexplained what Sherwood had complainedabout. Sherwood had sent him some materialdating as far back as APRIL 1994! Onewonders what Mr Nickson would havethought, seeing information which was soold. Why did Sherwood not complainearlier?
1 So, if you notice the quality has gone onrecording, or ever have the misfortune toget a 'chewed' tape, don't throw it away -a simple modification can make it nearperfect again.

1 So far, so good. But you cannot hope towrite a Pascal program in this way unlessyou know to start with what you are aimingtowards. In other words, you need to knowwhat commands and structures are supportedby Pascal, so that you can plan yourprogram in terms of these.
1 So far we have only entered sounds inchannel A of PATTERN 1. Move the cursor tothe start of the data lines in channel Band enter notes/values here in EDIT mode.On playback you will hear the data fromchannels A and B being played together.You can build up very complex soundingtunes using all three channels perPATTERN. You might like to put drum soundsin channel A, a bassline in channel B andthe main tune in channel C.

1 Provided you have the equipment necessary to run the CD this is a very worthwhile investment, although it is highly reccommended that you have the registered version of the Z80 emulator to take advantage of the virtual tape files and 128k snapshots. At around `20 this really is an essential buy for anyone interested in the Spectrum who has a computer capable of using the CD. For those without such a computer, but access to one there is a program to access the snapshots using a +D or Disciple disk drive.

1 On the humble Speccy we have little in theway of DTP but with some software like ArtStudio & Tasword (and of course a goodprinter) we can kick out some impressiveresults.
1 On the above circuits, all voltages arewith respect to the signal ground (SG)line. The following conventions are used:}

1 Oh yes; to copy SNAP READER4a, simplypress BREAK (CAPS + SPACE) then type:O
1 Oh yes! I'd better give Ray Smith amention before I forget. No doubt he willinclude a message to me in his column.z
1 Of course, if you wish to print out ascreen when the port is disabled thenyou'll have to save the screen to disc andload it in later when you've re-activatedthe port, and print it out then.
1 Of course, life is never wonderful (Iknow, Emma Wray's never answered any of myletters.. Sob), and there is a problem;the Spectrum cannot read these emulatorsnapshots. There are two reasons for this;firstly the disc format is different fromthe +D, and secondly the snapshot filesare different from the +D ones.
1 Of the two values, one gives a 20%increase in speed, the other 50% - a baudrate of 2250!a
1 OVERALL: 7/10 A bit too slow withoutfastram or an accelerator.D
1 OUT@ addr,byte is like the +D POKE@, but POKEs the Multiface RAM instead. Like the +D version, you can POKE a 16 bit (double byte) address directly. Eg:
1 OUT@ 12000,65535 would POKE 12000 and 12001 with the value 255. This command is useful when you're POKEing an address pointing to a piece of machine code or a font.

1 Numbers below 1000, or 1E3, don't benefitfrom E notation. VAL "100" and VAL "1E2",for example, are equal, and VAL "1E1" isless economical than VAL "10", which isbest left as PI*PI anyway! As a matter ofinterest, the highest number with whichthe Spectrum can perform calculations is1E38. Er, that wasn't actually veryinteresting, was it?!

1 Now, by using the bottom two rows of yourSpectrum keyboard, you can create notesjust like a real musical keyboard. (makesure you are in EDIT mode). As you playdifferent notes you'll see the notedisplayed in position 00. Creating a tuneusing these notes is simply a matter ofentering a note at position 00, advancingthe position by one (by using theSpectrums cursor keys) and then entering anote at position 01 and so on to make up atune. At default you have 64 empty 'boxes'per channel.

1 Note that the voltage values are inverted from the logic values (eg the morepositive logic value corresponds to themore negative voltage). Also a logic 0corresponds to the signal name being'true' (eg is the DTR line is at logic 0,that is, in the +3 to +25 voltage range,then the Data Terminal is Ready).
1 Note that the software touch screen willnot work while a ZX microdrive isconnected and will probably crash.However, it is compatible with theDisciple and +D disc interfaces.
1 Note that the pressure and temperature ofthe oil will change with speed andaltitude.]
1 Not only does this give a silly number oflives, it also gives the player an extralife because the extra decimal places keepit above zero for one extra repeat of theprogram!
1 Not knowing the size of a +D sector, Icannot give you any calculations, but ifyou were doing PC formatted disks then thesector size is 512 bytes, you would beable to fit 13.5 sectors into the Spectrumscreen area ready for compressing ! Trueit would look ugly, but it leaves you theremainder of the RAM for dumping thecompressed data before writing it to disk.
1 Not being one to boast, but contacts areespecially welcome from non-PC owners too.Everyone can have access to the 3500+programs I have stored on my PC hard-disk!
1 Nostalgia freaks may also be interested to know that there are CP/M and Commodore 64 disk with a similar content at the same price. There are various companies selling these CDs. I bought mine from PD Soft. Their adverts can be found in most PC and Amiga magazines.

1 Many readers of Alchnews will probably have one of the computers mentioned above, and for those people it is a great resource.

1 Many commercial programs use BIN on itsown for 0. In fact, BIN is not the onebyte it appears to be, and is no moreeconomical than VAL "0" itself. So we'vegot one up on the "professional"programmers - they may be machine codegeniuses but they just can't write asimple BASIC loader! Use NOT PI instead.

Your experience of usingthe machine tells you what commands areavailable, and how you can plan what youwant to do so that it works within thecapability of the machine. But becauseBASIC does not enforce a structuredapproach, BASIC programmers are lessconscious of this process.

1 In BASIC programming there are several setprocedures for dealing with a variety ofproblems. Among these, common examplesinclude the ability to repeat an operationa set number of times, using a FOR .. NEXTloop, or to make a decision using IF ..THEN. Similar structures exist in Pascal,although these often allow a higher levelof refinement than in BASIC. This articlecovers some of the most useful of thesestandard forms.
1 In AlchNews 14, we took a look at ribbonprices and suppliers. Since prices change,here is a revision of ribbons for theLC-100 and the new LC-90 and LC-200series. This service may possibly beexpanded to feature other printers andribbons. If you would like this, pleasewrite in with your make and model ofprinter.
1 In AlchNews 16, we gave a preliminaryreport of a voice controller, by KevinGurd. The system comprises of a box whichplugs into the Spectrum and allows you tospeak commands into your computer, perhapsto move an object in a game, rather than ajoystick.
1 In 48K mode, everything will be done asexpected, but a bug in 128K mode causes"RETURN without GOSUB". To be moreprecise: The editor (necessary to typeCONTINUE) destroys the GOSUB stack. InBeta Basic 4.0 this bug has been cured.

1 If this stops with "variable not found"(or a different error report), it'sbecause A$ is not an array (i.e. set up byDIM). The cassette routine in the SpectrumROM fails to exclude simple strings (notthe SCS ROM) but most disk interfacescheck this properly.
1 If there are no .SNA files on the disc, orif the disc is not of the correct formatthen usually (but not always) the programwill tell you so and return you to themain menu. Occasionally though, SNAPREADER can become confused by files thatit takes to be .SNA files, but aren't. Inthis case you will get garbage on thescreen, and if you try to load them theSpectrum will crash (just turn theSpectrum off for a few seconds then turnit back on and reload SNAP READER and tryagain on real .SNA files if this happens).
1 If there are .SNA files on the disc thenthey will be listed on the screen andpreceded by a number (or a letter, ifthere are more than nine files). You can6now do one of several things;

Not muchcan be done, although you could tryloading the code into a wordprocessor tocheck it yourself (if the program didn'tfind them but you do, either the addressesor password you gave were incorrect!).Don't be disheartened, though; it's wellworth trying it on all games you havewhich use passwords.

1 I've been rather busy lately. Afterpurchasing a lovely Star LC-10 from ArnoldYates of Chorley (send off for his list -it's the best!), I finally had a dedicatedprinter for the +3. When I invested in thePC, I had to reshuffle the office around,which could only really house two largemachines (by large, I mean with allhardware, drives, software etc.). Thereshuffle ensured the +3 had a dedicatedposition, and got it's Amstrad monitorback!
1 I'm not gonna tell you how to get around Arcade, as it's easy enough to work it outfor yourself, but just remember to delete most of your messages, or your message
1 I wrote to Mr Nickson, and explained thesituation. Some years ago, I orderedsoftware from Prism. It was faulty. I alsoencountered other problems with hisservice. However, I just ignored it,thinking it was a one off. I wasn'timpressed with Prism at all, so decided tokeep away.
1 I would like to tell you about the Amigaversion of the Spectrum Emulator. Thereare one or two about but the only onereally worth mentioning is called ZXAM andcomes in various guises. The first one Ican remember was version 1.3 and it wasn'ttoo good. The mouse pointer and the menualways stayed at the top of the screen!
1 I will cover the hack insert controllingcircuit the next time round.F
1 I was introduced to the Sega when someonebrought it to me for repair, which wassimple job because there was little wrongwith it, just a couple of open circuitwires - one of which came from the powersupply pack and the other was the antennalead!
1 I used the framework of the program to store a font in the Multiface, which would automatically be moved to RAM and be displayed. It was extremely easy to perform and worked well.
1 I thoroughly enjoyed ALEX. It is difficultto complete but it can be done and I forone felt very disappointed when it was allover and done with as I felt sure therewere at least another three or four levelsto come after I'd reached what turned outto be the final screen.
1 I think that's the lot. I'm off to bed now(it's 2:27 am) so thanks for reading thisand have fun with the .SNAps andeverything else Spectrum related.
1 I think that's all there is to be saidregarding SNAP READER's operation. IfanyoneZ
1 I think that this is a great point to endthis matter on, which we all agree hasgone on far too long. You'll find noAlchemist Research report on MartynSherwood and Prism in any more issues.Yes, there are people who are interestedin it, but there are some who obviouslyaren't. So, reports WILL still becompiled, but will be on paper. Simplysend an SAE and we'll send one to you.That way, the capacity of the issue is notrestricted in any way.
1 I then saved off the read data and calledthis routine again for the other 32K ofthe Sega ROM - the CD 4040 counters wouldnot have reset unless the power to thecircuit had been interrupted. The combinedvalue of the two counters at this pointwill be 8000 (0 after the next block isread in).
1 I rang the office of Mr Nickson, and I wastold that a Mr MARTYN SHERWOOD had writtenand made a complaint, and that Mr Nicksonhad called to arrange a suitable time.
1 I purchased this under rated game in 1988.It received an excellent preview in YourSinclair magazine and subsequent reviewand rating.
1 I know that Andy has decided to cut downon the Prism reports in AlchNews, but I'vebeen asked to comment on the recentsituation in the Gulf. No, no, I meant thesituation regarding the aforementionedPrism PD, or "PPD" as they are now known.(Does anyone know why?). <I assume it's sopeople see it and think 'ooh, a newservice', rather than 'Oh, yes - Prism,that poor service run by a liar who cannotcount'. Remember Gerald Ratner who calledhis jewellry stock 'crap'? He changed hisstores name to Signet after that cock up.Ed>
1 I hope some, if not all, of you are ableto help in this quest.@
1 I have used these utilities all the time,from the very first days of my Atari STthrough to the Amiga and PC etc.t
1 I have 4 meg Fast Ram, without Fast Ram itruns even slower.;
1 I gave Mr Nickson photocopies, provingsome of the activities Sherwood had beenup to, and explained how his lies possiblycost him his position at the Boys Club,and countless customers, and that Sherwoodwas just being spiteful and vindictive,and he was completely motivated by hatred.
1 I eventually came up with the idea ofanother circuit that would test theaddress lines. When they held 381D, theROM would be disabled and a zero would beplaced on the data lines, instead of a 2B(DEC, HL).
1 I believe that WIZARD GAMES are stillselling second hand 3" disks for around `1each. However, these disks could be uptoTEN years old, and have no guarantee ofquality and how they may have beentreated.
1 I attached two wires from the tags of thesocket to the appropriate wires of the +2tape wires and hey presto - workedperfectly!
1 I am not asking you to take a leaf out ofAndys book and supply us with an entire PDLibrary, but any help given will be justlyrewarded.
1 I am also in the process of making a leadfrom the +3 to a SCART plug. The groundpins are causing a little problem, butotherwise the picture is sound. Thecomplete wiring diagram will be here nextissue.
1 I am the person who uploaded all theissues of Alchemist News to the SpectrumEmulator site in Norway, and hopefully thebig boss man has had some more enquiriesabout AlchNews since !
1 I already had a printer lead, manufacturedby Alchemist Software's Lloyd Garland. Theonly place at the time to supply a +3 leadwas INDUG, who were charging well over`10. I paid just `3 for the parts and gaveLloyd the price of a pint for his trouble!
1 I . i . i . I . i . i . I
1 I loaded up the game on the tape -MOTORWAY. It's a simple game where youhave to move your little man to avoid theoncoming cars. Nice UDGs and very wellpresented.
1 I know, I know - this is a perfectillustration of messy programming. Whenthe password is found, the program simplyjumps out of the N-loop; very bad manners!However, this doesn't matter for such asimple program, as it won't cause anyerrors.
1 I hope you enjoyed this true story.Normally, these reports are usually onlykept for our review, but since thissubject has become extremely popular inAlchNews, we felt they would be wellrecieved. Next issue we will feature somemore reports on Sheffield ghosts, plus ourinvestigations.

1 However, the device doesn't have a throughport and my Spectrum setup is has aMultiface and +D on the back to runAlchemist Research, so it would mean a bitof unplugging to use it. This also meansyou would need some sort of port splitterbefore you could use the +D, so the factthe files were supplied on tape only was avalid one.
1 However, don't forget to close the outputfile when you've finished. It then'disconnects' the program and preventsrubbish going to it.
1 However, I was at work, so was unable tomeet Mr Nickson. What I could notunderstand is why he called. I had made anenquiry to the organisation in the past,to find if I would need to registerAlchemist Research, but that was someyears previously!
1 However, Richard has promised a newservice, EXPRESS SOFTWARE. At time ofwriting, no press releases have beenissued, but Richard promises a largeadvertising campaign!

1 Home computers store thier memory on aseries of silicon chips. Each memory chipcarries thousands of tiny circuits whichcan be either switched on, or switchedoff. Each of these circuits represents asingle digit in binary - a BIT. When thecircuit is switched on it represents 1,when it is switched off it represents 0. Within the chip, these tiny curcuits areorganized in groups of eight. Each grouprepresents a BYTE - that is an eight-bitbinary number, or two digits in hex.

1 For the purposes of the RS232 standard, a'circuit' is defined to be a continuouswire from one device to the other. Thereare 25 circuits in the full specification,less than half of which are at all likelyto be found in a given interface. In thesimplest case, a full duplex interface maybe implemented with as few as threecircuits. There is a certain amount ofconfusion associated with the names ofthese circuits partly because there arethree different naming conventions (commonname, EIA circuit and CCITT circuit name).The table below lists al three names,along with the circuit number.

1 Carl has only been a customer of AlchemistResearch for a couple of months, but inthat time has been a great pleasure towork with. He's pretty talented with aSpectrum, a great conversationist, and isa worthy member of our team. Despite beingan open ex-customer of Prism, we couldhave easily treated his new 'arrival' withscepticism, but we have all (includingother groups) welcomed him with open armsand gladly appreciated him speaking outabout the shoddy service he experiencedwith Prism.

1 At the time of this historic event, theAvenger was only a prototype - so even themost experienced pilots needed to quicklyfamiliarize themselves with its variouscontrols.
1 At perhaps the most critical point ofWorld War II, you take on the role of adive bomber pilot. You have been sentaboard the huge aircraft carrier HMS ArkRoyal, your mind on one mission - to seekand destroy the most feared German warshipon the high seas, the Bismarck.
1 At one point of the lane is a dip, a deadtree, and the point where a white figureruns across the road, literally inchesfrom the car, causing drivers to brakesharply, skid, panic and everything else!
1 As you can see, INT PI is half of VAL "3"in memory terms. Don't forget that PI onits own can be used whenever it will berounded up automatically (eg POKE X,PI orPAPER PI).
1 As to where you can obtain the actual .SNAfiles from; there are many sources, forexample:\
1 As the clock struck ten, I thought it washigh time we had overstayed our welcome.David, on the other hand, seemed to have nintention of going! In the end he had tobe forcible removed! It was then I wasgiven the final bombshell - could I takehim home?
1 As the Sega ROM could possibly hold 64K ofdata, I decided to load it to SpectrumRAM in two 32K blocks.j
1 As mentioned above, the address is twobytes long and requires two memorylocations to store it. The Spectrum breaksthe four-digit hex address; for instancethe normal RAMTOP address FF57, into twoparts, FF and 57.
1 As it turned out, the hack I needed to dowas in the first 32K of the game, address381D, a DEC, HL op code, which decrementsthe timer counter.
1 As far as can be ascertained, Mr Sherwoodadvertised these programs in January 1995,began distributing them in February, thenasked Theo for permission to do so inMarch! To quote from a letter from Theo toAndy Davis, dated 28th March 1995:
1 As far as I know there are no bugs in thisprogram (if you find any, please let meknow) but anyway:e
1 As everybody knows, the computer is farfrom sophisticated. When you boot up theSpectrum, EVERY TIME, the chosen randomnumbers will be the same! So, whatever youdo, do NOT buy a lottery number generatorprogram!
1 As digital signals (switched DC voltage,such as square waves) are used, as opposedto analogue signals (continuously varyingvoltage, such as sine waves) a very widebandwidth channel (such as direct wire) isrequired. A limited bandwidth channel(such as a phone circuit) would causesevere and unacceptable distortion andconsequent loss of information.
1 As an emulator it is superb. It is quiteconfigurable and incredibly easy to use.The only annoying aspect is that I wouldsay about 85% of games run a little slowerthan the proper spectrum, especially oneswritten in Basic.
1 As above, but with Disciple emulation onPC drive: `207
1 As above but REGISTERED with tape supportand extra utilities to read +D discs andcreate GIFs from SCREEN$s. Tape supportvia sound card or interface: `15
1 As you may have noticed, many BASICprograms use VAL expressions, eg LET A=VAL"20" instead of LET A=20. If both thesestatements do the same thing, surely thelatter is shorter and therefore morememory efficient? No! In fact, all numberscarry a hidden five-byte qualifier,without which the computer
1 As mentioned earlier, don't enter anynumbers in the last three values per box.These values are used to enhance the soundwith added effects and is covered in fullwithin the ADVANCED guide.
1 As for programming, since the voicecontroller works in Basic, programming issimple. You need not use the keyboardagain! You could even create passwordsystems based upon your voice, or secretcommands!

1 Another project which I had been puttingoff for quite a long time was the externaltape socket for the +2. When the internaldrive went, some five years ago, I quicklyadded a jack plug with some wire to theappropriate wires of the +2, hoping tofind the time to get it done in thefuture. I never did!
1 Another full catalogue program. It usesAndy Pennel's PRINT#14 routines to squeezemore than 32 characters on one line. Theprogram is slow enough, without thisroutine making it worse!
1 Another case of illegal distribution byPrism PD involves the AlchNews 10C update.Mr Sherwood disagreed with an articlefeatured in this update, and in a letterto Andy dated 14th February 1995 he said,and I quote:

1 An integral force in both the Atlantic andPacific naval campaigns, Grumman Avengersalso engaged in anti-submarine operations.They were carried out from small escortcarriers beginning in February 1943. Bythe spring of 1944 they had eliminatedenemy submarines from all the majorshipping lines.
1 An identifier is defined as a letter or a digit.2
1 An executed IN A, (F7) instruction fromthe Spectrum will take the IORQ, RD andA3 of the Spectrum address lines low. Whenthis occurs the final output from thegated nor gates will also go low, enablingthe ROM and the hex tri-state buffers.
1 An essential utiltity, giving you an extra5-10k per disk. It allows you to defineexactly how large you want your cartridgeformatting. This could be useful if youproduce a microdrive resident program andwish to avoid leaving any excess space onthe disk.

Afterlengthy correspondence with Mr Sherwood, Iagreed to print another article retractingthis statement.

In order tointerface two DTE devices, it is usuallysufficient to provide a 'flipped' cable,in which the pairs (TD,RD) (RTS,CTS) and(DTR,DSR) have been flipped. Hence, the TDof one DTE is connected to the RD of theother DTE and vice versa. It may benecessary to wrap various of the handshaking lines back around from the DTR oneach end in order to have both ends work.In a similar anner, 2 DCE devices can beinterfaced to each other.

1 Above it are 168 memory locations whichhold the representations of 21 userdefined graphics. However as RAMTOP is asystem variable, it can be moved down inmemory, pushing the GOSUB and machinestacks down into the spare bytes. This isdone when you are writing machine code.Usually a machine code program is tuckedin above the lowered RAMTOP so that itcannot be overwritten by a BASIC program. 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 Above the spare bytes is the machinestack. This is used by the machine itselfwhen a BASIC program is RUN. But when youwrite machine code you get a chance tomanipulate it yourself.

1 A secondary channel is sometimes used toprovide a very slow (5-10 BPS) path forreturn information (such as ACK or NAKcharacters) on a primarily half duplexchannel. If the modem used supports thisfeature, it is possible for the receiverto accept or reject a message withouthaving to 'turn the line around', aprocess that usually takes 100 to 200 ms.
1 A routine for skipping over values in atable uses the system routine STK-CONST todiscard each value. STK-CONST normallycopies the value to the address inregister DE, but the codes at 13308 and13309 tell it to dump it at the start ofROM, avoiding the need for a seperateLOSE-CONST routine.

1 A program like this has been available forthe Spectrum +3 for quite a while, butrequired an external disk drive. To usethis program, you will need any Spectrum,a +D interface and a 80 track, doublesided disk drive. The program has not beentested on a SAM or Disciple.

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 5 CTS. CLEAR TO SEND. This circuit is thesignal that indicates that the DCE isready to accept data from the DTE. Innormal operation, the CTS line will be inthe OFF state. When the DTE asserts RTS,the DCE will do whatever is necessary toallow data to be sent. At this time, theDCE would set CTS to the ON state, whichwould then allow the DTE to send data.When the RTS from the DTE returns to theOFF state, the DCE releases the channeland then set CTS back to the OFF state.Note that a typical DTE must have anincoming CTS before it can transmit. Thissignal must either be brought over fromthe DCE, or provided by a wraparound (egfrom DTR) locally at the DTE end of thecable.

1 4 RTS. REQUEST TO SEND. This circuit isthe signal that indicates that the DTEwishes to send data to the DCE (note thatno such line is available for the oppositedirection, hence the DTE must always beready to accept data). In normaloperation, the RTS line will be OFF (logic1 / MARK). Once the DTE has data to send,and has determined that the channel is notbusy, it will set RTS to ON (logic 0 /SPACE), and await an ON condition from theDCE, at which time it may then beginsending. Once the DTE is through sending,it will reset RTS to OFF. On a full duplexor simplex channel, this signal may be setto ON once at initialisation and left inthat state. Note that some DCEs must havean incoming RTS in order to transmit(although this is not strictly accordingto the standard). In this case, thissignal must either be brought across fromthe DTE, or provided by a wraparound (egfrom DSR) locally at the DCE end of thecable.

Note that atypical DCE must have an incoming DTEbefore it will function normally. Thissignal must either be brought over fromthe DTE, or provided by a wraparound (egfrom DSR) locally at the DCE end of thecable. On the DTE side of the interface,this signal is almost always present, andmay be wrapped back around to othercircuits (eg DSR, CTS and / or DCD) tosatisfy required hand-shaking signals iftheir normal function is not required.
