Happy 45th Birthday to the Sinclair ZX81!

Release Date: March 5, 1981

@tsturm That was before I got involved in the #Cambridge micro industry. I did a lot of work on the ZX83 (the Spectrum was the ZX82 and the QL was the ZX83, at least as far as the numbers printed on the custom chips were concerned).
@TimWardCam Oh wow - that's awesome! I had a QL and used it quite a lot for some time after it came out. What kind of work did you do on that machine?

@tsturm I worked for GST. The main thing we did for Sinclair was 68K/OS, which they never used - but I got three trips round the world and a new kitchen out of it. We also did some software products to go with the QL as released, which sold in small numbers but allowed me to claim that I've authored a book that you could buy in shops - the user manual for the assembler. I also spotted a bug in one of the QL chips during development and got them to fix it.

I ran a project to rework the QL hardware to make a financial information terminal for Australian Associated Press, which is where the trips round the world came from, allowing me to visit Ayers Rock, Singapore, Hawaii and India on the way there and back.

I pressed some of the buttons during the press launch of the QL. But we'd had an awful lot to drink the night before, followed by Bucks Fizz on arrival at the press launch, resulting in me missing a cue so Clive had to repeat it.

That's my handwriting on at least some of the labels on the picture. https://en.wikipedia.org/wiki/68K/OS

You can't have that much fun as a programmer these days.

That's a great story! πŸ˜†

@tsturm We were on our third G&T each before we spotted the little card on the table which said "all spirits in this bar are sold in doubles". And then we had the chef's tasting menu which came with various wines with the various courses. Intercontinental hotel, Park Lane.
