What we tend to forget was the excitement this machine caused! YOU could write a useful little program that did something which would otherwise have been quite laborious or, of course, YOU could make a little game maybe like Pong! The power the ZX81 put at your command, that was the rush, that was what made me demonstrate it to friends at every opportunity. Now we have wonderful machines but we've lost control over them, they've become appliances rather than tools for the mind.

Oh how I remember my ZX81. It was my very first computer and I learned an awful lot from it in a rather short time. I did find a short ribbon cable that plugged into the back of the computer and the other end plugged into the 16K ram pack. That cured all the problems with the ram pack. I opened the case and modified the video output from a modulated signal to a composite signal. It was a very simple fix that took less than an hour to do. I did the modification so I could use the video monitor I purchased instead of the tv set. And the video output looked much better. I built a real foundation in programming in BASIC for myself with this computer. I still have my ZX81. It's in a sealed box. It might not ever work again but that's ok. I take it out of the box every once in a while and wow do the memories start rushing back to me.

The manual (the same as for the Zx-81), lots of example code, and ramped the difficulty up gradually. The keyboard was crap, but the way it let you press one or two keys rather than typing in an entire command or function name helped. I have many fond memories of laying on the carpet, bathed in the glow of my tiny black and white TV, creating games, solving homework assignments, and running out of memory all the time.

My father was an environmental engineer; it was on his ZX81, in the summer of 1981, on which I programmed my first video game. His machine was FANCY, it had a 64K(!!!) memory pack, which was so large that the CPU couldn't address it all! You had to use a POKE command to switch between the upper and lower 32K blocks. He used them as microcontrollers, a sort of early '80s Arduino: by attaching data acquisition and relay control cards, he made settling tank controllers for a mine in the Sierra Nevada mountains. He could buy them for $30 each in 1983, and nothing could touch that price point.

(the standard cassette interface was 250 baud) and a 40 column thermal printer, ( I rapidly went through 2 ZX printers and their aluminized expensive paper! ); all connected thru an interface attached to that lonely port at the back ( I think the brand name of that interface was AIO and it was about half as deep again as the Sinclair ) Once you got used to it, the membrane keyboard was really quick because of the way Sinclair BASIC incorporated it's use into the language

Very good and succinct summary of the purpose and abilities. The absence of colour and sound (save the tape screech) might have been mentioned but the BASIC of the ZX81 is quite good given the limitations of the machine. And the manual is a terrific introduction into simple programming. The ZX 81 at its core was ZX80 with a ROM upgrade (and simplified circuitry, of course). IIRC you could even turn a ZX80 into a ZX81 by plugging in the new ZX81 ROM.

I still have one, now with a modern SD card adaptor and 32K RAM pack that doesn't wobble. It is unfairly criticised. For the price, there was literally *nothing* else available. And it was the first computer to make it into regular shops when WH Smiths took what they saw as a gamble and agreed to stock it. Prior to that you had to find a specialist "computer hobbyist shop" or buy mail order from the back pages of electronics hobby magazines. The ZX81 went mainstream and you could toddle off to Smiths (later Boots and Dixon's) and buy one off the shelf....take it home, plug it into your existing TV and off you went. There are reasons beyond nostalgia why there is *still* new software and hardware being made for this little machine.

There was a fundamentally different gaming cultures in the UK and US. The UK was using their own machine, the Zed X, Acorn, BBC, etc. From the view of the present-day retrogamer, gaming "went" to the UK: but for the developers, the companies and by any other measure, there was no "back and forth", no interchange, or only on a very limited basis. The Japanese were also active all this time. Your perspective seems a bit odd to me.

I bought one of the kit ones and kept it for a long time. I learnt so much with it. They only had 4 o 5 ICs (chips). The Zilog Z80 processor after which the machine's name is based, a ROM chip which included the machine code routines for the Z80, 1 or 2 RAM chips depending on the chip type and the ULA (unified logic array) which was a huge set of logic gates on a chip with customisable connectivity. Despite what some people think, none of the chips were made by Sinclair, but Sinclair's cleverness was in the use of the ULA, the machine code routines and the overall design. The earlier ZX80 did not use the ULA and had to use a larger number (about 15 I think) of hard wired logic chips.

If I recall, graphics were limited to character generation but there were all permutation of 2x2 pixel blocks which were used for some games including a flight simulator to generate a 3D cockpit runway view. I still have my original TS-1000 and carts as well as another TS-1000 and 16kb memory pack in respective unopened boxes, still with Payless sticker on them.

My poor excuse was that it was the 80s and access to information was poor. The local library never had any decent computer books so learning any programming was difficult. We did have the manual back then I believe, but again, I was never a bright kid so never understood most of it. I also never realised that you could record programs to the tape. I blame my high school because although we had computer classes in the 1st and 2nd year, we used BBCs and this was in the late 80s. But it was one BBC to 2 kids and me being shy back then would never get a chance to have a go.

I don't think that the ZX81 is unfairly treated, even when this video was made, there was a very active community for this monochrome monolith. It endured the 1980s and became an icon. It's only misunderstood sometimes from a perspective outside of the UK and other parts of Europe, but even some American commentators today are catching on to how its price point and simplification was important. One has to remember though that for North America, the home computer market started around 1977, so by 1981 the ZX81 looked obsolete already. But not so in the UK.

Can you create a video on the Casio PB100? I could programme it like my Spectrum, but carry it in my pocket!

First computer I ever owned. Managed to get a form of sound from it in m/c by switching the screen on and off rapidly which made my little black and white tv make a lot of noise. Sounded awful! Rand Usr 16514!

That was basically the first computer I had, but with a different name: Timex Sinclair 1000. I never got the cassette to work so I had to type in the code every time.
