I had a
Commodore 64. Man, just looking at the pics of the thing brings back waves of nostalgia <sniff>
I used it for playing games, usually Beachhead, Impossible Mission and Elite. My mate used it for programming in Basic - what a geek!! Had it for about three years. I upgraded from tape to 5 1/4in floppy disk. The external disk drive cost me $350!!!!
Should have kept it. I'd still be using it to play Elite. Sigh. I miss that game....
