atari 2600 schematic originally drawn by Jerzy Sobola (with some additions by myself)
Magic Floor - a search game (with sample source code for the no$2k6 assembler)
pdroms.de - webpage for homebrew games (nice idea, but doesn't work on any of my browsers)
And, don't miss Oystron and Thrust - the best homebrew games I've ever seen.
