From Greg Thompson:
The following are the first 14 pages from the "hardware" Maze Game
report from Fall 1976 that Mark Horowitz, George Woltman, and I designed and
built for the MIT 6.111/6.112 digital design class. All together there are
79 pages in the report plus 73 pages of specs on the 7400 series TTL/DTL
SSI/MSI/LSI boards it was built from.
The first jpg image contains a picture of the 6 rails of logic that made up the
hardware Maze game. It appeared in a Scientific American article on
Microprocessors by Hoo-Min Toong in Sept 1977 describing the MIT digital
lab. Since the game was well beyond what was ever implemented before in the
lab classes and was played with so much, the professors and TAs kept it
assembled for years after the class was finished.
