The Odyssey cartridges
Here are the layouts of the printed circuit boards of the 12 Odyssey cartridges. These layouts were made by testing the cartridges, and later verified with the Odyssey service manual (though only the first ten were tested since #11 and #12 were not found yet). On each cart, the top side is shown on the left, and the bottom side is shown on the right. There are no contacts between the two sides. Note that if you use an 800 x 600 resolution to view this page, the layouts are in true scale (at a few pixels approximation, but this will not prevent the one willing to complete his cartridge set from making the missing ones).
