      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.

    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.

    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). 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."
