Re: "ignited the PC revolution"
@Pompous Git - Oh yes, I do remember the Sorceror; your mention of it brought back a memory of seeing an advert on TV for it. My first computer was a Sinclair ZX-81 (with 1K of RAM, 544 bytes available for user memory!) which I got for my 16th birthday. Needless to say, I got upgraded the following Christmas to a VIC-20.
@JeffyPooh - yep, they sure do go back. Although there was none of the open hostility displayed by today's warring fanboi crowds; back then it was more just a friendly rivalry. Incidentally the C64 used the 6510, not the 6502 - that was the VIC-20 that used the earlier processor. :)
@AC re: Dick Smith Wizard: It might have been spelt "Wizzard" actually, it was so long ago I can't be sure. It was a pretty basic system that only briefly saw the light of day before being overshadowed by the likes of Sinclair, Tandy and Commodore.
