1 " You can start at any of the five mazes, each of which is larger than one screen and will scroll sideways as you move a- cross. There is a map of the current maze always visible at the top, but you aren't really likely to get lost.":
1 " You aim your shots by moving alittle pointer around the edge of the table, then set the forceof the shot and fire. Controls are by keyboard and work fine. This game only requires a joy- stick in real life."
1 " When you collect a treasure, it disappears and the score thusgained appears briefly in its place. Nice touch. There are al-so keys to be collected if you are to travel far through the tomb, each door needing its own."
1 " Welcome to our fifth issue."
1 " We confidently expect to be joined this issue by many new readers who recently found a Spectrum in their stocking. If this is you then welcome, you not only have rather large feet,but also access to the largest collection of software available"
1 " We chose two decks for review,the CPD-8300 from W H Smith and the Superscope C-190 from Boots.Both of these have extra fea- tures which are of use in data applications, although only the W H Smith deck is specifically designed for computing."
1 " This one has almost everythingthat you miss on a cheap deck, tape counter, tone control, lev-el meter, pause, cue, review andauto- stop. It also has useful features found very seldom on any deck, like variable speed and three modes of level con- trol, manual, auto, or limiter."
1 " This magazine is made up of a number of articles and programs chained together in a manner similar to the 'HORIZONS' tape that came with your computer."
1 " This is the memory block mov- ing instruction with the mnemon-ic LDIR and the hex code ED B0, (two bytes) or 237, 176 in deci-mal. We use it to move a SCREEN$which we have stored high in thememory into the proper screen memory where it belongs."
1 " This is the first two-computergame for the Spectrum, and one of the first pieces of software to make use of the microdrive network, if not the drives them-selves. It can, however, also beplayed on a single, unadorned"
1 " This is a fast moving maze game with lots of monsters and treasure and the emphasis on ac-tion. The skulls gnash, snakes wriggle and the mummy walks, in fact, if it doesn't move, grab it, it must be treasure."
1 " This is Ian Andrew's follow-upto Mined Out and was launched with a top score competition. Ifthere is still time to enter, you might be interested to know that Ian reckons that the keys score better than joysticks.":
1 " There is an element of forced coyness about the name of the original, as a prominent manu- facturer of board games felt it was too similar to a game they have been marketing for some time and insisted that the titlebe changed."
1 " There are two other screens toshow the relative positions of all players, and details of all the properties. This last will allow trades and deals to be en-tered, and the Spectrum can evenhaggle on its own behalf.":
1 " There are slide controls for tone, volume, and manual record level. There is plenty of volumeavailable from the EXT SP socket(Spectrums like it loud). A rot-ary control will vary the speed by + or - 20%, very useful for"
1 " There are several implementa- tions of the 'ball plying game' on the Spectrum, but this is thebest that I've seen so far. It succeeds partly because it does not try to do too much."
1 " There are only six balls in the triangle at the start, and the rules of the game are comic-ally simple to anyone who under-stands snooker. All you do is pot the balls. The scoring is a bit more intricate but the com- puter does that for you.":
1 " The size is 10*8*3 inches, butoriented the other way than us- ual, wide side on, with a slopedtop. Fewer 'audio' type featureswhich you don't need allow a lower price at just under forty notes. "
1 " The ones that ED B0 expects usto use are named B,C,D,E,H and Lbut we will treat them as pairs in this routine. The Z80 CPU hasa lot of instructions which workon two registers as a pair be- cause the address bus is two bytes (16 bits) wide."
1 " The object is to rescue a per-son of the opposite sex from thecity, which is overrun with hugeants. The boy can save the girl or (my favourite mode) the girl does all the hard work while theboy lounges about on a wall, no doubt cheering on the ants."
1 " The more good, cheap software a computer has going for it, themore users it will have, and themore users, the more people willwant to supply software. I don'tsee how any of us can lose, pro-vided the electricity holds out."
1 " The first recorder I ever usedfor a computer program was a Leevers-Rich Synchropulse model C, full of valves and originallymade for the movie industry. In those days only IBM and Honey- well had dedicated tape machinesand the rest of us used whatevercame to hand."
1 " The easiest way to use it is to go through the articles in sequence, following the prompts.However, there is a table of contents on the next page, for those who wish to go straight toa particular article or program."
1 " The convenience of not having to mess with a lot of pieces of paper is offset somewhat by the limited view of the board duringplay. As our snap shows, only a few properties at the position of the player currently moving are in view on the main screen."
1 " The complexity of the display precludes the use of more than one colour in order to keep the speed required for animation, a trade-off that is well worth- while. The hero and heroine, or":
1 " The chickens aren't pushovers either. One touch from a hen andit's all over, so the poor farm-er is harried somewhat as he goes about his egg collecting. Good thing they're kind of dumb."
1 " The Spectrum implementation isa faithful copy with all the oldfamiliar places. The major ino- vation is that the computer can be one of the players, as well as keeping track of the board, bank and all the property deeds."
1 " The Kempston joystick is sup- ported, or you can define your own control keys. This seems to be the best solution for games keyboards, as it will allow for the use of other joysticks (likeSinclair's own) which imitate the keys, as well as catering "
1 " Suffice it to say that this isthe game where most people wouldrather spend the night in jail than in a Mayfair hotel. There is neither need nor room for me to go into the method of play orrules for this one.":
1 " Some manufacturers try to keepcompetitors from writing soft- ware for 'their' computer, hop- ing to cash in on aftersales. Ifthey manage to hog the market, it just puts people off the com-puter."
1 " So we will need three more in-structions to load the register pairs with our numbers, and the numbers themselves, which will each be two bytes. One last in- struction, C9 hex (201 decimal),is needed at the end to return"
1 " So this is where GROUCHO's duck got to! I don't quite know what it's doing here, because itnever got out of its cage while I was playing, but if it should do so the feathers apparently start to fly."
1 " So I have loaded HL with zero,which is the address where the ROM begins. That should make a nice mess. We'll see shortly. If you haven't played with machine code before, I hope thatthis has provided some insight."
1 " Sandy White, sculptor, has putaside traditional materials for long enough to create a city outof electrons. It can be viewed from four points of the compass in superb 3D perspective, using a programming technique which heis attempting to patent."
1 " Putting the whole snooker tab-le on the screen is an exercise best left to the Beeb. CDS have cut the game to suit the graph- ics and have ended up with a most realistic and precise ball and table game which is neither snooker or pool but works well."
1 " Power supply is mains only. There is no built in mic, but you can use it as a normal re- corder if you wish. There is a small speaker and a special mon-itor switch that lets you listenat a low level while recording."
1 " Power may be supplied by mainsor battery, or even an external six volt supply. A removable mains lead is provided. In/out plugs are similarily diversifiedwith both DIN and mini jacks "
1 " Please note that some files load in an unusual fashion. Do not stop the tape until you see a flashing prompt and hear the hooter."
1 " Our resident Wizard, the re- doubtable Prang, claims to know this secret (and all others, come to that), and with a pass of his hand has caused a furtherclue to appear in a back issue of Der Speigel. Can it be?"
1 " Only you can decide if the ad-ditional facilities are worth the extra cash. They do help to ensure that a dumb mistake does not destroy the preceding hours of cleverness, which is invalu- able for serious applications."
1 " Of course, there are other ways of writing it down, binary for instance, but most people prefer to work in hex. You may have noticed that the numbers following the load instructions were backwards. Complaints to ZILOG, MOSTEK, and INTEL, not"
1 " Naturally, the world's first tape magazine decided to have a close look at what was availableon behalf of ourselves as well as our readers. As the whole magazine passes through one cas-sette deck, that deck must work."
1 " My only quarrel with all this realism is that the control keyswere often slow to respond. Thiscaused me to flood my diesels on several crash dives. It is inBASIC mostly, and you just have to press the key when it's look-ing. Can use Protek joysticks.":
1 " Movement is by the 'turn left,turn right, move forward' methodand it is here that the game is let down slightly. There are a lot of control keys (four for the grenades alone), all of themfixed, not user-definable, and no joystick option."
1 " Let us first dispense with theone design blunder. There is on-ly a single control for both re-cord level and volume, and as there's no auto record level op-tion, you have to keep twiddlingit from save to load and back."
1 " Kempston and AGF joysticks aresupported, and this game is fastenough to need them. The controlkey scheme is usable (though notuser definable) but I always getflustered. The smart bomb is on-ly available via the keys, as the fire button works the laser.":
1 " It is such a nice bit of kit in every other way, too. Pity. This one is dedicated alright,there is even a switch marked Spectrum/Other. I don't know what it's for, but it certainly speaks my language!"
1 " It has one major deficiency asa data recorder, which is that you still have to unplug one lead when recording to avoid thedreaded feedback loop. Most of us are used to this by now, but it is still a non-feature."
1 " Input and output are isolated,you don't have to jerk the ear lead out when saving. Great! Youget computer oriented Load, Saveand Tape Running indicator LEDs too, and the level meter has a light. The meter markings aren'tthe standard VU scales but just"
1 " Indeed, a company called Com- modore has become the major mak-ers of mono cassette decks mere-ly by ensuring that their compu-ters (they make something calleda Vic) will work with no other."
1 " In the year ahead, we Spectrumusers can view with aplomb the crashes and rescue bids as vari-ous lesser micros fail in the marketplace. There are so many of us already that when Sir Un- cle Clive is made Pope and loses"
1 " In action it is even more im- pressive. The hero is a lovely mover and the MAZIACS most hor- ribly are not. The battle anima-tions will knock you out. There is a cute bit if you don't keep your warrior moving. After a few"
1 " If you only use your tape to load commercial software or read'Spectrum Computing' then this rule is fine. Indeed, this maga-zine used to be put together on a cassette machine that cost less than a tenner."
1 " However, your laser only fireshorizontally, so the monsters can get you if they catch you ina vertical passage. They keep being regenerated from certain spots in the maze, and careful timing is needed to get past."
1 " However, the visible assuranceof recording that a level meter provides, plus the convenience of a tape counter for finding files will make either of these machines worth the extra to any-one who is programming or using tape to store data files."
1 " GGGGGGGGGGGGGGGAAAGGGGGGGGGGGGAAAAAAGGGGGGGGGGGGGGyyyyyyyyyyyyAA
1 " Conventional wisdom regarding tape recorders for use with com-puters is that the cheapest is usually best. This is because data, unlike music, is not im- proved by the sophisticated hissfilters (try saying that aloud!)which come in quality recorders."
1 " Conceptually, this is the ZX81program MAZOGS, but the transferto Spectrum graphics cannot be termed a mere re-write. As with all of Don Priestley's work, it looks like some kind of hardwareupgrade in the display area. Onesimply marvels at the graphics."
1 " But the manufacturers have suddenly realised that no one uses a mono recorder to blast out the latest Beatles hit any- more, and have begun to tailor their product to the use that wehave all been putting it to."
1 " But before we can use ED B0 wehave to tell the computer where the block of memory we want mov-ed is, and where we want it to go to, and how big the block is.We do that by loading the appro-priate numbers into the CPU "
1 " Both have a black mark: Boots needing the ear lead unplugged, and Smith's single level/volume control. Perhaps the choice is which defect bothers you least."
1 " Besides the walls, you have toavoid spikes and stay out of thewater. Survive all the hazards long enough and you are bumped up a level and get to see more of the maze, at an increased speed. Take a good look at our snap at level 6, you will have"
1 " Besides getting all the eggs, which you must do to bring on the next screen, you get extra points for trampling the piles of chicken food that are dotted around the place. I know, it is not the way I'd run my farm ei- ther. There is only room for one":
1 " Automata have done it again! Whether that's a good thing or not rather depends on your feel-ings about PIMANIA. Some people would run a mile. Others will begoing without sleep to chase theclues to the name of the secret Hollywood personality."
1 " As an exploring archaeologist you are naturally armed with a laser, and one that is particu- larily effective against spooks at that. You also have one smartbomb which clears the screen of nasties at one blow."
1 " Apart from the proper letters (the ones that are on tape) thatwe get from our readers and put in the magazine, there is a lot of old fashioned paper post thatcomes in which we can't share soeasily. But we certainly take note."
1 " Amid the suggestions and, er, suggestions (the only comment wehave had about Hacker's Hangout so far is that 'they certainly do') can be found the occasionalanswerable query. The most fre- quent of these is, 'how do we do"
1 " AUTOMATA have a deserved rep- utation for what can only be termed 'daftware', but this of- fering does not have the usual 'miss' single on the back, nor any lunacy not inherent in the original game."
1 " A most impressive offering forthose who are bored with invaderthumping and prepared to pummel their own organ of contemplationinstead. Win through and you getto help write JUMBLY II."'" The puzzle, for such it is, is"
1 " You get the 'Star Letter' prize for this issue, Keith, and not for the flattery. We love it of course, but it's the BORDER tip that clinched it. Plus the fact that yours was the only letter. A pack of ten C15 cassettes is on its way."
1 " We must be the only magazine whose readers write in asking for more adverts. I can only assume that the advertising staff at all the software com- panies are not Spectrum users, and hence can't 'see' what is inside the magazine."
1 " Q TO GO UP - A TO GO DOWN P TO GO RIGHT - O TO GO LEFT "''" KEY=50 Pts - WHITE MAN=10 Pts BONUS of 10 times the number of sheets after every sheet"
