It made me quite sad reading about this news, Sir Clive was an amazing bloke, way ahead of his time and a bit of a hero of mine. I think he was treated quite badly by the British press and didn't actually get alot wrong. Obviously his big mistake was the C5 which ultimately cost him dearly, but look at the interest in electrical vehicles now!
Our first home computer was a Video Genie, which was a TRS80 clone, a little bit like the Commodor PETs in schools and most computers around that time were much of a muchness, but were good to get you into basic programming. A couple of years later I received a ZX Spectrum 48K for Christmas, wow what a machine! Incredible capability and value for money in its day.
I remember when I was studying for my OND in Electronics and having to do 6502 assembly language during the day, it was so tendious. I used to get home and write my own games on my Spectrum to cheer myself up, it was a joy to use. The best two games I wrote were a 10 pin bowling game and a Tank battle game, all with full colour graphics and sound. Then there were the commerically available games and they were amazing compared to what we'd seen before, two of my favourites were Elite and Alien 8. I remember us having to build our own interfaces from kits so that we could use joysticks and other peripherals.
They say that we the first Computer Games generation, and look at the size of the industry now and how many people it employs. When I did my Masters in Computing at Liverpool John Moores, you had the option of just studying Computer Games Technology such is the demand for those skills now.
A few years ago there was a cracking film about the technology pioneers from the 70s/80s called 'Micro Men'. Might be a nice tribute for the BBC to show it again, although I'm not sure that it shows Sinclair in the best light, but its still a good watch.
