      I *did* write a task-scheduler for the Spectrum once, which could sequence eight different tasks. I incorporated something derived from it into some embedded controller code (running on a Z80) for a company that did, well, embedded stuff. I heard a bit later on, that the company had been bought by a large electronics manufacturer, and the simple scheduler I'd written while off my tits on magic mushrooms one night while I was in 6th year at high school, has since been incorporated into the braking system controllers of a very high-end automobile...

    I must have a dozen Spectrums of various iterations kicking about here - including 2 of the early blue-key types complete with microdrives and microprinters.

    I even have a couple of 'docking bases' which allowed (IIRC) you to network up to 16 Speccys together in series.

    It just really suprises me that there is enough interest still going in the spectrum to actually warrant a magazine relaunch.

    'Back in the day' I used to own my spectrum primarily for gaming. The magazine to have was 'Crash' (complete with cover-mounted cassette). Now there was a real magazine; it wasn't even glossy ;)

Of course in those days they had just been developed, that's why the disks were single sided, single density, rather than the later double sided double density capacities. The Opus Discovery disk could store 180K formated. Not very much these days but much more than the mircodrive's 85 - 100K and much faster and more reliable.
          • When the Amstrad made Spectrum +3 came out, 3" disks were already an almost 'dead' technology, having been beaten by the superior 3.5" disks. 3.5" disks were "proper" disks with tracks, 3" disks used a single spiral track going from the outside of the disk to the inside. 3" disks had to be explicitly ejected and turned-around to use both sides, where true double sided capable drives were becoming available for 3.5" disks. 3.5" disks, as mentioned, were therefore obviously superior to the 3" disks.

      Sinclair machines were very popular over in Europe, right? Could anyone tell me why they took off over there and not over here?

      The first machine I bought was a Sinclair ZX-80. I bought it because it was very inexpensive. It was the first complete system to sell for under 100 pounds, which was revolutionary cheap for the time.

      The circuitry was amazing. It had 1 KByte of memory which also serverd as video memory! I remember that someone crammed in a chess program into that. The original BASIC interpreter was 4K. (Why are all program so damned big nowadays?)

      To make the system very cheap, it had no dedicated video circuitry! You stored characters in RAM and ended each line with 0x76. (The less text you had on display, the less memory it used.) To display the text on the screen, you set a special bit in hardware and jumped to the RAM character buffer. The CPU would start to fetch instructions from the text buffer, but the hardware would clear all bits fed to the CPU (00=NOP). Instead the RAM output was fed to the BASIC ROM which now served as a character generator. When the end of line was reached, the 0x76 code was fed to the CPU which interprets that code as a HLT (halt) instruction. So no more bits were fed to the display until horizontal sync, which gave the CPU another interrupt. So with a minimum of 74xx logic gates video text could be generated at low cost and extremely low memory requirements. Of course, the screen went blank when executing BASIC code.

      It was an amazing machine and I have many fond memories playing with it. The schematics was included so you could do some hardware hacking as well.

I found it was a great machine to learn about computing - you had a Sinclair Basic interpreter as the main interface & Z80 assembler underneath. I spent many happy hours coding & hacking games on it. It & its predecessor, the ZX81, were what got me hooked on IT & software development. One of the great things was full manual it came with & fairly straightforward books you could buy detailing the full ROM disassembly!

But, just as knowing how the mechanical bits of your car works can make you a better driver, knowing how the internals of the CPU (not just a rough idea of what's inside, but actually understanding what's going on) can make you a better programmer.

    ...Bill Gates' 640K remark, you'll just love Sinclair's thoughts on 32-bit systems. Yes, Sir Clive Sinclair was convinced that nobody needed more than 8 bits. :) The QL used an 68008 processor, which was largely a 68010 that could only shuffle 8 bits into out out of the processor at any one time.


    Sinclair was notorious for over-hyping his products, advertising them long before they ever came to market, and aimed much more for numbers than for quality. (If he hadn't built that stupid C5, Sinclair might well today have the kind of grip Microsoft has. Clive had been inventing and marketing products from radios to metal detectors for several decades before the ZX80, so he was very well established. In the early days of home computing, he very probably had more cash on hand than Bill Gates and Paul Allen. If the QL had been true 32-bit, and he'd not gone bust over building an electric car from washing machine motors, there is every reason to believe that the industry today would be bowing to him.)


    Legend has it that one reason his computers were so cheap was that he'd buy defective parts. His argument, apparently, was that home users were never going to put industrial-sized loads onto their computers, so there was no point in buying chips up to that grade. Consumer electronics barely existed, back then, so the cheapest alternative was to buy stuff that had failed QC.

      Just like the 8088 used in the original IBM PC, which (if I may quote) could only "only shuffle 8 bits into out out of the processor at any one time".

      I suspect you'll find the reason that Sinclair chose the 68008 for the QL was largely the same reason Motorola offered it - cost. It's FAR cheaper to design and manufacture boards with 8-bit buses than with 16- or 32- bi

      Legend has it that one reason his computers were so cheap was that he'd buy defective parts.

      The memory chips in the secondary bank of the 48k ZX Spectrum were all faulty 64kbit chips of which either the top or bottom half had failed testing (so they were "cheap as chips" when he bought them - haha.) They were put into the Spectrum, wired up so it only accessed whichever 32kbit actually worked properly, and the defective half was just ignored.

      • They apparently did the same thing with the Tandy Color Computer for a while, during the early days of the 32K upgrade. Or at least so the rumour went [unc.edu].

        Not for very long, though; soon enough 64K chips were cheap enough that nobody bothered selling the half-bad ones.

    • I don't think that the problem with the QL was the 8 bit bus, at the time nobody was doing true 32 bit, even the IBM PC was 16. The real problems were the crappy graphics - only 4 fixed colours in hi res, the choice of the microdrive as the storage medium and the fact that it was over a year late.

      The root of the problems was that Sinclair went overboard on cheap, with the QL people wanted a $3000 computer for $800, he decided to go for $600 and in the process just made everything a bit too cheap. A real k

    Currently I have a P4 thingy and an old AS/400.

    Also, I'm building some 8bit single board machines. Z80, 6502, 8086, 6800. Good fun, though running them at 1mhz doesn;t really get anything done.

    the other Sinclair formats and clones include the QL, SAM Coupe, Timex/Sinclair, ZX81, Z88 etc

    Just to be pedantic, the Sam Coupé wasn't manufactured by Sinclair, nor was it exactly a clone as it had many capabilities in excess of what the Spectrum could do. Some links:

    The Sam Coupé Scrapbook [mono.org] - all-round comprehensive information

    Shameless plugging of my own site [intensity.org.uk] - mostly software rather than hardware information

    SimCoupe [simcoupe.org] - a free and legal Sam emulator for Windows, Linux, MacOS X etc.

    To anyone not involved in the scene, it probably seems very odd to be holding a show for such old computers. But I spent very nearly ten years using that old 8-bit computer, which means it lasted longer than any other computer I've bought since at many times the price, and in that time I've met a lot of people who also used it, and who have had much influence on me in various ways. Most obviously, my interest - and now my job - in programming can be traced back to the days I spent trying to squeeze every drop of performance out of the Z80 that I could possibly get (and back then, every t-state counted!)

    Obviously it's interesting to go to these shows and see what new things people can still do with the old technology. But even more than that, I'm hoping just to have another friendly chat with a few of the people I've known for about the last decade and a half.

      In all fairness though, Zilog's instruction set was invented after the 8080 set, by a gang of people who used to work at Intel. So really, the Zilog guys had the benefit of hindsight.

    Fond memories indeed!

    I grew up on this computer. Back in Russia, Spectrum clone kits were very popular. They were cheap, the electronics were "close enough", such that intricate timing-based video tricks didn't quite work, but everything else worked.

    I never used the real thing for more than a few minutes. Instead, I used a Russian clone called "Hobbit" (just googled this [tarunz.org]). My dad was involved in selling them, and so I got one. Apparently only 50000 were made. The great thing about this clone was the PC-style extended keyboard, which obviated the need for some of the trickiest key combos.

    Paired to a small monochrome screen, I used to write (at the tender age of 11) programs and games for it. One game that I wrote was very simple: there was a line through the screen, a person in the middle, and a car running left to right. The sole control was the spacebar: pressing it at the right time would make the person jump long enough for the car to pass under. Despite that, I remember adults playing the game for 5-10 minutes, far longer than I expected.

    Now, I was not one of the l33t assembly coders: instead, I stuck to good old onboard BASIC. One of the niftiest features it had (as far as I was concerned at the time) was the ability to define custom (USR) characters. You could define tens of 8x8 pixel chars, and then print them as normal letters. I used to sit down with a graph paper notebook, separate it into 8x8 cells, draw objects and then shade pixels. I wrote small animations, typically involving cars, little people (Lode Runner, anyone?), helicopters, parachutes, robots, and stuff exploding. The exploding was accomplished by XOR'ing X, O and other characters over the site of explosion.

    Of course, there was the BEEP command. The computer's manual (or some Spectrum-related book) came with a listing to play the funeral march. Much fun was had by shortening the durations of the notes in that march, making it sound upbeat. I tried writing some of my BEEP statement music, but I recall the results were pleasing only to me and not the family :)

    Back in Soviet Russia... oh wait, this was post-Soviet Russia, the black market was rampant and much tape copying was had. Name any game and you could pick it up for less than $1. Childhood memories include sitting in front of the TV, having cleaned the tape head with alcohol (of the rubbing kind, not vodka), hoping that the 5-minute load of this game will succeed.

    The particular version of the Hobbit that I had also included a version of the LOGO interpreter. Since all the books about logo that I had were in Russian, and the interpreter was in English, I pretty much failed to invoke all but the basic drawing commands (DRAW was translated fine by the dictionary, but most other keywords weren't).

    I probably didn't play quite the same games that most Spectrum users did. Some of the ones that I remember include "Lode Runner" (amazing), "Chuckie Egg", "Iron " (yeah!), "Commando", "Knight Lore", "Target Renegade" (boy was this one a pain in the ass to load), "Lotus Esprit Turbo", "Nebulus" (good stuff!), "Saboteur" (how many hours spent on that baby), "Chequered Flag", "Chase HQ" (oh yeah!), "Deathchase" (teh winn!11!!), "Wec Le Mans", "Crazy Cars 1" and "Crazy Cars 2" (nice!), and more that I am too tired of listing. I was not cool enough at the time to play "Elite" (required too much concentration :) ), although I did have it. "Elite" was regarded as "the game to play", from what I remember. Strangely enough, I don't think I've ever played "Jet Set Willie".

    Unfortunately, one sad day, the Hobbit blew a fuse. My dad decided to try inserting a wire for the fuse, since we couldn't find an appropriate replacement fuse. That's when I learned the meanings of "fuses don't blow for no reason" and "magic smoke."

    Recently, I bought a ZX Spectrum from UK off eBay, but the working condition wasn't clear. I still haven't tried it.

    I remember being 10 or 11 years old in the early `80's and seeing an ad for the ZX81 in the back of a Popular Science mag. I really wanted one of those things as I had not yet used a computer or owned one. A few years later, after I had been using an Atari 800, bought a Timex-Sinclair 1000 from a kid at school who didn't want it. Even after using the Atari, I thought the TS-1000 was cool. Now, over 20 years later, I'm talking to a 18 year old kid at work. He has a TS-1000 from a yard sale and doesn't know a thing about it. Even more sad, he's not even tried to use it. There is a whole generation or more that only knows Windows and have no idea what is underneath. Yeah, the kid is a geek and knows HTML, but is afraid of the stuff underneath. How sad!
