Here's a fun one for the weekend.  A retrospective of the Commodore 64 and it's place as a great game machine.  The C= 64 sold something like 17 million units and is, to this day, the single greatest selling computer model of all time.  My first computer was a Commodore 128 which was basically an expensive C64 with a lot of worthless hardware in it.  I don't think I ever did much with it other than run C64 programs.  Well, when I programmed in Basic I did so in C128 mode.  You could renumber lines there.
