Here is a YouTube video of a 90 minute presentation celebrating the 25th anniversary of the Commodore 64 home computer. The C64 was a groundbreaking machine and I know I'm not the only one who learned a lot from this wonderful machine and similar ones like the TRS-80, the Apple II, the Atari 800, and the TI-99/4. I programmed Commodore computers in BASIC, 6502 assembly language and Forth. Great stuff.
Go check this out for a fun romp into the past. The presentation touches on much more than just the C64. http://video.google.com/videoplay?docid=3754836267385299753
