back to article Look back in Ascii: Computing in the 1980s

Reg Hardware Retro Week Logo When I landed the job of Doctor Who Script Editor in 1981, I knew I needed a computer. Actually it was something I'd known since the age of 12, but back then you couldn't get started for less than half a million dollars. Now you could pick up a Sinclair ZX81 for a shade under fifty quid in kit …

    Commodore PET

    First Desktop computer I saw back in 1977/78.

    Beat the port-a-punch punch cards at school.

      I recall the keyboard being a lot more nasty than that one in the picture.. that looks like the C64 keyboard the Pet, I had as a kid had tiny angular low profile square keys, in a horrible yellow with silver stick-on inserts..

      still, It was fun to mess with.

          So the 2000 Series had the chiclet Keyboard (and tape) as here. The 4000 series had the better keybord and screen as here

          So that picture in the article is some sort of bastardisd/Photoshopped version with the 2000 label and screen but the 4000 keyboard?

            If memory serves, you could upgrade the keyboard of the 2000 series with a 4000-style one. It was just a matter of opening the case, disconnecting the old keyboard's ribbon connector, removing the screws that held it in place, and installing the new keyboard.

            I had (on loan, for a while) a 2000-series PET that had a full-size external keyboard added on, The external keyboard had a ribbon cable with a Y-connector; we opened the case, plugged the new keyboard's cable in between the planar and the old keyboard, and closed up again, with the ribbon cable squeezing out between the halves of the case. Both keyboards worked, which was useful for 2-player games (which we wrote ourselves, of course - kids these days using store-bought games...).

    First laptop?

    I thought it was the Radio Shack (Tandy in UK) TRS80 Model 100. These were used by field reporters for newspapers for quite a while as I understand it. They came with a "built-in" modem (you needed a special cable, and it didn't dial). They are actually pretty nice machines (I have one).

    The one I have I expanded its RAM from 8k to 32k using chips that weren't available in 1981 (its release I believe).

    Now for the real trivia: This was the last machine that Bill Gates actually worked on the software.

    1. Trygve Henriksen

      Re: First laptop?


      The TRS-80 Model 100 arrived in 1983, a year later than the Epson.

      It was probably beaten by the Casio FP-200, too, but that one was labelled as a 'Handheld computer' in the manual...

      The TRS-80 is said by some to be the last machine that BillG wrote SW for himself.

      Most of the built-in apps will crash with a hopeless error message if you try to start them without first creating the default file it needs to store its data...

      Re: First laptop?


      You are right about reporter using the TRS80 Model 100's. I worked for a newspaper in the IT department back in the late 80's/early 90's. We had these built into attache cases with a specially built rechargeable battery pack and an acoustic coupler. This made the computer useable over prolonged periods of time and allowing the reporter to send in their copy from any telephone that was available (including public phones). The receiving computer was a PDP 11/84 mainframe.

      Wish I had kept a few of them. Alas they were binned many years ago and are probably at the bottom of a land fill.

      1. Peter Gathercole Silver badge

        @Simon Round

        A PDP 11/84 was a single-chip PDP 11 processor (J11?) in a minicomputer rack (it had a UNIBUS rather than a QBUS which made it a proper PDP 11 rather than a micro PDP 11 like the 11/83).

        It was definitely *NOT* a mainframe, but a 16 bit minicomputer with address extension. IIRC, it probably was the most powerful of the whole PDP/11 family (I mean real PDP 11 rather than a VAX 11).

          You know that, I know that, but to today's younger people, if it isn't an x86 or never appeared in the pages of PCW or Computing Toady it's a mainframe.

          Yes it was probably the most powerful commercially available PDP11 ever sold by DEC. 16 bit registers, 64kB address space per program (give or take), 4MB total addressable memory via memory management.

          Nice, especially when booting RT11 out of silicon disk (back in the days when you could fit a whole OS onto a <4MB disk).

            OK. You both got me bang to rights. I've used the term 'mainframe' without really thinking about it.

            To be honest I never had anything to do with the PDP 11/84. I worked on the PC, MAC, Unix side of things and the 11/84 was, to me, a beast that sat in the corner that the editorial and pre-press department used.

      Organiser II, Apple ][

      Heck, I've typed insane amounts on the Psion Organiser II but granted, that was code. I actually miss the simple flat file databases it had - you could mess around with the record buffer in code and get very creative with what you could store (which you had to, the max size ever to fit in that machine was 2x 256k flashpack).

      It would have been useless for serious amounts of text, and I agree with the general opinion on the 3c. The 5 wasn't bad either, but I never got that to sync properly (that was IMHO the eternal problem).

      As for the Apple ][, you could save yourself some money by assembling it yourself - buy the motherboard and start soldering (there was a Pear II at some point, not quite original, but annoying enough to ensure Apple went solidly proprietary :).

      Oh, and IBM: my first PC was a clone with a Turbo button (remember those?), using DoubleDOS so I could do more than one thing at once :).

    Exidy Sorcerer

    Best name for a personal computer ever.

    Can't comment on the beast itself as I was about twelve when they went out of production and I was still trying to get the RAM pack to stop wobbling on my ZX80. All I knew was, I wanted a computer called a Sorcerer.

    1. Steve Evans

      Re: Exidy Sorcerer

      I remember the first (and only) time I saw one of these. It must have been round 1981/2. It belonged to an American boy who'd just come across to the UK when his parents relocated.

      I remember him being very proud of his DIY ram upgrade, which comprised of a load of piggy-backed chips on the existing RAM, and a load of thin wires running off across the board.

      These day it's an obvious upgrade with the chip selects being the thin wire runs, but at the time I thought it was akin to witchcraft.

    Happy(?) memories...

    Great trip down memory lane for me as someone who cut their computing teeth on many of the eclectic beasties mentioned in the article.

    My first "proper" job included the maintenance of a whole menagerie of micros for my local FE college and this collection included a couple of dozen CBM PETs, largely 4000s, but a few 8096s, too.

    Someone at the college was obviously a fan of Commodore products as we also had a number of C64s, too. There was a diskette we had with a proggy on it that made the floppy drive play the tune "Daisy Bell" by causing it to perform some probably rather dubious operations. Check it out here:

    1. I learnt to program during my final year of primary school on a ZX81, complete with wobbly RAMPack.

    2. I eventually was bought a VIC-20 by my parents, to whom I immediately demanded it be replaced with a more usable C-64.

    3. A short time later, I got a modem for the C-64 that plugged into the cartridge slot, and opened up the world of fledgling BBSs, Prestel/Micronet and of course Commodore's own Compunet.

    4. I became addicted to Shades (a MUD type game on Prestel).

    5. I lost all my pocket money for about 5 years due to MASSIVE phone bills. ;)

    6. Graduated to an Amiga 500, then 500+. Got heavily into the Amiga demo scene.

    7. Moved over to an Amstrad 1512, which I slowly added an ISA based HDD, a 3.5" floppy drive for drive B: and a new NEC V30 CPU to replace the Intel 8086 and double it's speed. Also added an ISA modem card to continue my Shades addiction.

    These days, I have a 42U rack of servers in my garage, and practically a laptop/tablet or desktop in every room of my house, plus a pile of unused kit, just... in... case...

    Getting in to computing in the early days created a feeling that even the purchase of today's latest shiny phone or gadget cannot even hope to re-create.

    1. Simon Round

      Re: Ahhh....

      Quite scarily similar to my story.

      1. My first computer was a ZX81 which I got in the 3rd year of comprehensive school. Learnt to program it and had wonderlust for computers since that day.

      2. Didn't move onto Commodore computers. Instead moved to Acorn BBC's and as these were the computers we used at School.

      3. When I started working I bought a modem and rigged up a telephone point in my bedroom. Also got addicted to BBS's. Somewhere I still have my little red book of BBS numbers, usernames and passwords. Of course the BBS's are long gone but it was happy memories.

      4. Got addicted to some of the online games on the BBS's. Shame I can't remember the names of any of them.

      5. Ran up a big phone bill. Game my dad a few grey hairs and worry lines until he mentioned this big bill and he did not know how it had got so big. Of course I confessed as, like many others, I did not associated what I was doing with the cost of the time online. Luckily as I was working I was able to pay the bill and was very very carefull after that.

      6. Moved onto an Amiga 500 and later a 1200. Joined a local computer club where we met up every few weeks in a rented room at a social club where everybody setup their kit and demoed the latest software, hardware, etc.

      7. Work bought Amstrad 1512 and 1640 computers for the accoutants which we then networked using some third parts expansion cards, cables and a 1640 (with hard drive) as a central server. These were the days of Lotus 123 and Supercalc. Long before Microsoft Office. I remember using an early Norton Tools to defragment 300k 5.25" floppy disks.

      These days I don't have a rack of severs bit do have computers in practically every room of the house. The wife won't let me put one in the toilet.

      I agree with your last sentiment. Those days were very exciting. There was a certain euphoria every time you open a new game, read about the latest computer or Hardware addon. I just don't get the same feeling with modem gadgets.

      1. Alan Edwards

        Re: Ahhh....

        Very similar here too...

        Started on a ZX81, moved on to an Acorn Electron, then an Amstrad PC1512. Not sure I ever had a modem on those machines, I think my first was a 14,400 on an Olivetti 486 when I got my own place. I'd had modems at work for a while, though.

        Excitement at school when the Research Machines 380Z was finally pensioned off for a network of BBC Micros with a gigantic Winchester hard disc in the corner. It was probably 5 or 10 meg, but was physically the size of a BBC. That would have been about 1985.

        My 'rack' of servers is two HP ProLiant Microservers, one on top of the other. One is a 6Tb (4x2Tb RAID-5) NAS, the other is a VMWare ESXi host. I seem to be buying too many tablets at the moment, I have a ViewSonic ViewPad 7, a ZTE V9A and an iPad, and I'm still eyeing the Samsung Galaxy Tab 2 7-inch.

      Started with a Beeb, played with Econet at school. Moved to RISC OS...

      I now use a PC for my day to day stuff, but in the corner is an Econet file server, a Beeb, a RiscPC, and three other RISC OS machines. They see less action than they used to, sadly. Though I hope that the port to the RaspberryPi will be ready by the time I order mine.

      I wonder if part of the problem is that the old machines invited you to enjoy them. The circuits were easy to understand, the processors weren't a nightmare, the API was fairly well exposed, and they all came with a language built in. Even the Speccy and the Oric had dialects of BASIC.

      As opposed to modern stuff where the box itself can't do anything without some sort of OS to load. Linux contains programming tools, but installing and setting up an entire OS is a world different to a '>' prompt. Windows? There's pretty much nothing "out of the box". Game consoles? I picked up a dead XBOX for a euro and I now understand that I'll need to modchip it simply to replace the broken harddisc. Things these days are aimed at providing a consumer-oriented service, and as such try to keep you out of the machine instead of welcoming you in.

      Once upon a time, instruction manuals told you the processor instruction set in one of the appendices. Now? You probably need to Wiki to find out what processor it actually uses...

I would like to hear from Reg Readers about their experience of chorded typing, because I have a sausage-fingered friend who swears keyboard keys are too small for him.

    That made me feel Old

    Those were interesting times, for me DOS ruled the world and though I did look at an apple in the early to mid eighties I stayed with the PC. 8088 and then the Toshiba 286 portable, the one with the orange screen which travelled the globe with me - I must have been stronger then!

    You were right about modems and the magic of being able to collect data from some far away device and do interesting things. In my case I worked in telecomms amd logging into distant switches and collecting data was a new kind of magic. Automatically processing data that used to take months of manual effort was done in a few seconds. It was cheaper to buy and run a PC than to put ink on paper. Operator staffing schemes could be planned and designed by collecting data 24 hours a day, deciding when staff were needed and how schedules should be prepared. Network upgrades could be planned on the basis of real hard data collected in near real time and analysed within hours if not minutes.

    In the days before Ethernet, sneaker net worked almost as well for the PC farm I had with really cheap PCs collecting data and one big machine with a hard disk and a 286 chip processed the data. What had appeared to be massinve amounts of print data was acutally so small in data processing terms that I had both RS232 ports active at the same time collecting data from two sources and running separate collecting routines on DOS based 8086 machines.

    By the mid eightries I had a software models of the switches we used running on my home computer and talking with data manager models on the portable to test out the programs I was developing. This helped to automate data entry so that accouning records were taken from the main frame IBM machine and after suitable editing and reformatting fed straight into new stwitches as they were brought into servce. Two week's work done in two hours, with full printouts of every error found - not like the results of manual key punching from paper records.

    My first experience of computers had been with the Z80 processor the code all written in assembler. It drove a training facility only we changed the system and had 24 expensive training programs that no longer represented the way that the facility needed to work. Re-programming assembler at 'up to 6 bytes at a time' in HEX through direct memory pokes teneded to teach you to be careful and dump the memory frequently.The alternaitive was to see many hours of careful work evaporate on the first run of the test.. The recording medium was a cassett tape using the output of a modem into the recorder's sound recording facility - no digital recording at that time.

    All in all interesting times.

    One last thought, my PC farm grew quite large and was all run off the building UPS, as things developed it drew more power than the main frames in the 'proper DP centre' that ran the billing and other commercial functions.

    At least I confined my efforts to off line devices, unlike the character in another country who was denied access to a PC. He worked out how to run his programs on the swich (central office) he was supposed to manage. They worked but nearly crippled the central office with the extra load.

    As I said interesting times

        Well as I sit here in the study the original box for my Z88 is on a shelf next to me, and the Z88 itself is sitting nearby in its neat carry case. Somewhere on another shelf is my copy of 'Z88 Computing' by Ian Sinclair. Oh, and I've just found the original User Guide.

        I remember taking my Z88 to a PC conference in Holland (those were the days of companies paying to go on conferences). I took my conference notes typing directly into the Z88.

        Definitely one of the first truly flexible portable computers; lightweight, not too big, useful software that matched my business software.

    Eagle Computers?

    Their first IBM compatible was also launched in 1982 although they had been producing pre-DOS personal computers for years before that. They were built like brick sh*thouses thanks to their multimedia pedigree. They had to survive being thrown into vans and planes on a daily basis.

    Here I am sat at my desk doing my IT support stuff for a big, nay huge multinational IT firm. Slowly a tear is rolling down my cheek, as I look back to the golden 80's.

    In 1989 I start as an operator of several machines

    In the very early 80's my wife's PhD theses was written in Scripsit on a TRS80 model 1 (with expansion box).

    The expensive bits were the floppy disks! 84kB (I seem to remember) a time - which subsequently got updated to double density through a US-sourced "doubler" board that had a different controller on it....

    Relocating the RAM (on bigger, 64kb chips that weren't available when the machine was on the market) to the keyboard greatly improved reliability as like others of the era, your whole document was in memory!

    Scripsit got hacked to make it do all sorts of things that more modern printers could support - like addressing individual pins which we used to print Greek letters!

    After the thesis, it got used to produce - both analysing the data and writing up - what has become quite a seminal paper in its field that's still findable on the Web as a scanned image of the (new printer ribbon!) dot matrix printout produced by the TRS. Someone even wanted a copy of the (compiled Basic) program I used for the analysis which made me rather chuffed..

    One of the things that set the TRS80 apart was the fact it had a decent Cherry keyboard - that taught me to touch-type although the keyboard unit needed a wrist rest as it was thick...

    Happy memories - I think its still in the loft!

      Re: TRS80's

      Interesting that the Smithsonian's keyboard unit doesn't have the numeric keyboard which means it must be a "level 1" from what I remember...

      Another memory was the "tamper protection" that quite a few people used: load the code into memory in one place then use the "block move" instruction to move it somewhere else to execute - made it somewhat harder to disassemble (and modify!)... Meant all the long jumps went to the wrong place if the code hadn't been moved correctly...

        "Another memory was the "tamper protection" that quite a few people used: load the code into memory in one place then use the "block move" instruction to move it somewhere else to execute"

        That was copy protection? I thought I "invented" that technique to be able to load cassette based games from floppy disk into higher than normal address space then block move them back over the top of TRS-DOS (or later, LDOS). The same technique I later used on the ZX Spectrum to load cassette games from a Rotronics Wafer drive, which, like TRS-DOS loaded it's OS extensions into low RAM where the default ROM based OS would normally load programmes.

        Early TRS-80 copy protection consisted of the game being a full 16KB so you couldn't load a copy programme first. This wouldn't leave enough RAM to buffer the read before write copy operation. Unless, of course, you got a lower case mod which converted the 7-bit 1KB screen ram into 8-bit, from which you could then load and run the less than 1KB copy programme. Those who were rich would have a 48KB RAM upgrade (pretty much required if you were running floppt drives and TRS/L/MultiDos.

        1. Neil 44

          Re: TRS80's

          No, it was "tamper protection", not "copy protection". It meant you couldn't dissemble the executable from the disk image, change it and re-assemble it (easily!).

          However, if there were Copywrite statements in the program, they were the first bit that got "patched" over as they were spare space - the longer the message the better :)

          was it piracy as we owned the program (usually!) and were just making it do what we wanted...?

      Re: TRS80's

      I wrote up an A-level compsci project on my TRS-80 Model I Level II and printed it out on a daisywheel printer that was ear-shatteringly loud! (even inside an "acoustic cover"). I'm sure it was even louder than the golfball and line printers at Uni.

    I started on a 48K spectrum that was my grandfathers before, that got me into coding when I was 8, I remember spending hours typing games in.

    I was lucky that my parents brought me an Amiga 500+ when I was 10 I think,

    Graduated to an amiga 1200 years later, and loved it, while my friends had game consoles and joypads, I was playing battle isle, playing flight sims and writing apps/games.

    I have to say I owe my love of computers and my entire career to my grandfathers 48K spectrum...

    Getting a bit emotional here whilst remembering....

    Kicked off with a ZX81, when I started college in 81/82 then worked my way thoughvarious Spectrums, and then a QL before buying a Zenith 8086 cheap from Morgans - expanded the memory by buying and inserting DIL chips. None of this ram strip nonsense then. Soon learnt that in 88/89 Pcs werent much fun and bought an Amiga 600. Bought my first hard disk for the Amiga £250 for a 2.5" 60MB.

    Bought an psion LZ64 second hand back in the late 80s, then upgraded to series 3, then 5MX.

    Sold the Amiga and bought another PC in about 94. added soundblaster CD and sound card and a modem.

    Best memories are

    1. Getting a Token ring network and novell server (2.0a) at work in a tea-chest (had been stripped out of offices and rescued from skip!) I then figured out how to put it all together and network the PCs, and setup email in the room. I worked for Employment training in those days and we had barely any money for kit. at the time email seemed magical!

    2. Setting up a headless linux based box as an Mp3 player attached to my stereo system back in the late 90s - had an LCD screen and IR remote, and I could put my CDs in the loft. Everyone thought I was mad. Also networked my first house at the same time.

    3. My Psion 5MX was awesome. I bought the Ericsson SH888 phone with the modem. In 2000 I was uploading photos and reports using the setup whilst cycling the End to End. Near John o Groats met up with a party of school kids doing the same. they were using a laptop the size of a small suitcase and a digital camera with a 3.5" floppy disk drive and had to grovel a loan of a power socket and the youth hostel's phone line. I took the CF card out my camera, stuck it in my psion, and uploaded the photos over the mobile to my website completely wirelessly - The kids were amazed. It was a proper compute anywhere connected device.

    I agree with @james51 - The N900 is great, but the 5MX was a legend - still have 2 and ne is one my desk in front of me. would love an updated one with wifi/bluetooth.

    Been an exciting ride over the last 30 years - The next 30 should be a fun ride

    UK hobby computing started in earnest in 1977...

    Those who started home computing in the 1980s were Johnny-come-latelies. The first true UK designed hobby computer was surely the Nascom 1 release in December 1977. With a proper keyboard, screen output and supplied as a kit with full circuit diagrams and monitor listing, this was a proper hard-core hobby computer. Many were those who cut their programming teeth on this and the Nascom II released 2 years later. I still have mine, and a few years ago, at least, it was still working.

    My first serious project was a porting of Dan and Kathleen Spracklen's Sargon chess playing program to my Nascom II, a slow and laborious process when I had no floppy disk drive.

    The Nascom 1 featured on the first ever issue of Personal Computer World.

    1. Fred Flintstone Gold badge

      Re: UK hobby computing started in earnest in 1977...

      I think it started earlier in the US. I can remember playing Wumpus on a friend's Kim 1. Hex keyboard and display, 1k RAM and a tape recorder for storage..

    2. a well wisher

      Another Nascom'er

      Sounds like we trod a VERY similar path

      Whilst I originally started with an SC/MP project from Elector magazine

      I too moved on to a Nascom 1 ( although mine was a home build based on the circuit diagram of a mates official unit, on a large wire wrap board) - I think its safe to admit that now !

      Also added a home brew disk controller based on the old 1771 chip IIRC

      Even more of a coincidence, I too ported Sargon to it from the 'paperback', that was a lot of lines of assembler to wade through - worked though ! - was well chuffed at the time

    4. JamieL

      What's all this "bought" malarkey?

      Nah, "proper" hobby computing is when you get the handful of chips (CPU, RAM etc) wire them up with veroboard and wire-wrap to create your own. Not quite an early adopter (early 80s for me) but had to wait until my teens to be allowed to play with such delicate toys.

      Write an O/S (hand assembled, natch) then burn onto a EPROM, plug into your machine and see what happens when it powers up.

    Exidy Sorcerer

    I had a Sorcerer here in Canada for a year or two. I extended it with a huge external box with space for a pair of 8 inch floppy drives. I was always amused by the expansion slot devices, which were in 8-track tape cartridges. I remember a truly impressive Dr Who game that used the programmable character set to do a full-3D flying-through-space game, a bit like asteroids. No native sound output, however - I had an external one that did off/on via a pin on the parallel port.

    Proper keyboard, upper and lower case, able to hook up floppy disks - excellent!

    But, what is that switch in the middle of the bottom of the front? Mine didn't have one of those.

    TRS-80 Model III

    I first programmed on an IBM 704. It had vacuum tubes. But the first computer I took home was a TRS-80 Model III. It was either that, or an Apple II. And the TRS already had a monitor, and didn't need a silly add-on for capital letters. The cassette tape storage was miserable, but it worked, and eventually bought a Model IV and switched over to floppies. Novels were written on those computers. They're still with me, having been ported to CP-M and then MS-DOS.

    The most miserable part about the Model III was that you could not trust it to save your files if you had more than 32k of memory. Radio Shack wouldn't believe us. We eventually cut the memory from 48k to 32k, and it behaved just fine after that.

  33. Shee

    I began my computer career on Apple II clones, I had 3 or 4 of them, and as parts gave up I would pinch from one to make the damaged one work again, while I tried to find spares. They worked with 3 external drives and a pile of discs - no built in programmes. My favourite programme was the Bank Street Writer followed by another programme called something like News Writer (I could write in columns and add clipart from a library of thousands.) Those were the days! I smiled at the original post talking about CP/M, remembering the hours I battled with that and the joy when I overcame another obstacle. I had an Osbourne CP/M machine, listed as "the first luggable". But the Z88 was the first true portable that I had, and the first one I ever took on a long haul journey for making notes while I was away. Eventually I had to move over to Windows, and then move onwards and upwards from there. But the 1980s were testing times, and great fun, the 90's and Windows 3 weren't bad either. It's all gone downhill since then. Sob, sob!

    I used the both the original Microwriter (with single line red LED display) and its follow up with an LCD display. I have never been able to type as fast, as I could with those machines. I am still not a fast QWERTY user and reckon i could still type faster today using a Microwriter keypad. Sitting here now, I think i can remember at least 80% of the Microwriter chord alphabet; this, nearly 30 years after i last used one; once learned, never forgotten.

    Too bad

    I did not save any of those early computers like Apple II, Pet, ABC 80 and the Sinclair’s Z88.

    The ABC should have been mentioned, perhaps.

    Seeing the Sinclair’s Z88 I wanted one right away, but then I think it was the most annoying "computer" I have ever used, terrible quit frankly, even if I liked the rubber keys.

    I still think that Visicalc the first spread sheet program ever, and originally made for the Apple II+,

    was the first and only software that has really surprised me. That was something really new and surprising. As far as I remember Visicalc tried to patent it but their lawyer told them not to.

    In those days patenting things was not as easy as to day. What a disgusting mess it has become since then.

    Sorry Christopher, if you're reading I need to talk Doctor Who for just a second. I'd just like to say Frontios is one of my absolute favourite Doctor Who stories, the whole thing was great from start to finish.

    I'd love to see the Tractators revisited in the new series, I'm sure with CGI they could do justice to them curling up into a ball like a pillbug. That said, the recent Silurian story borrowed very heavily from Frontios with people being sucked into the ground which is a bit of a shame.

    Epson PX-8

    My first non-toy machine was an Epson PX-8 CP/M laptop, which had two auxiliary processors as well as the main Z80, and another Z80 in the bolt-on wedge-shaped 120K RamDisk that fitted nicely under the machine. The build quality was wonderful, the keyboard was good and solid, and it even had a pull-out carry handle. Unfortunately, the screen was only 8 lines (of 8 columns). I can't remember what the battery life was.

    I knew a few other users of these; the only one who didn't have difficulty soldering the mini-DIN 8-pin serial connectors was a surgeon who specialized in re-connecting nerves in childrens' hands.

    80s computing with no real mention of the Amiga. launched int he middle of the decade and spanked all those other toys into the end of the 80's people could even afford them in the UK ..the amazing A500 batman pack dropped to 399 quid - which was, for that amount of compute, and incredible offer...and the start of computer/console + games bundle era.... still going strong with eg PS3/Xbox360 bundles...

    1. Steve Evans

      The Amiga and Atari ST were a late arrival towards the end of the era of completely incompatible machines.

      Also, as you mention, the Amiga wasn't used for much more than a games console (yes, I know the Speccy wasn't much better), but my fond memories of the time involve lids off and hacking about with the inside. My Beeb started life as a model A, got a DIY upgrade, sideways RAM, dual controller floppy interface and all the toys added by me with a soldering iron.

      To me a computer isn't "real" until you take it to bits and modify it. :-)

    Ooh memories

    Started with a zx81 saved from paper round and bought 2nd hand just as everyone started to save for the Spectrum.

    Built a joystick adapter to take the Atari vcs joystick which was directly soldered to the keyboard header in the zx81. Sold quite a few of these to friends and family.

    Used to visit my schoolmate John and his dad Dave Looker who wrote Zuckman and Frogger for the zx81. They continued into spectrum, Dragon32, and cpc464 games and never looked back.

    Moved on to the Texas Ti99/4a whilst the schools had BBC and Econet with Wordwise for the word processor on Rom chips.

    The college had Atari ST before the OS was on ROM. Upgraded a few months later.

    Started work in 1986 on Sperry (unisys) and Tandem and ended up on ICL, IBM and AS400 gear.

    Moved over to Novell in 92 when Ethernet cards were £1000 quid each. Windows NT in 1998.

    Now it's all AD, GPO and not so much fun. Can't wait to get a Raspberry PI.
