The ZX Spectrum was one I didn't have. You couldn't even get a clear TV picture, they were garbage, and the keyboard was horrible. There was a persistent rumour going round the geeks at school that if you held down the M key and turned it upside down, all the keys would fall out, but everyone who had one was too chicken to try it with their own Speccy. To this day I don't know for sure it wasn't true.
My first computer was a Commodore Vic-20, then an Acorn Electron, then a Spectrum +2 for a short time, the one with the integrated tape deck, then a Commodore 64 then a Commodore Amiga 500+.
The best game on the Speccy was called The Wild Bunch. It was a text based game set in the old west, where you had to go from town to town finding and duelling with members of a gang of rustlers. Some of the text games were too difficult for kids, when I think back. There was another one called Hampstead which was impossibly esoteric. I remember the Adrian Mole game as well, that was easier because it was multiple choice.
