Other key parts include the CD74HC08PWR, SN74HC573APWR, 74HC04PW,118, SN74HCS00PWR and MC74HC74ADTR2G. By type, the board carries 103 capacitors, 28 ICs, 14 resistors, 10 inductors, 4 connectors and 1 jumper.
From the project
design files for the gametank hardware implementation
The current GameTank version that actually fits into a neat case and looks like a console is Prototype3.
The "Combined" folder contains most of Prototype3, and is named such because certain system sections were previously on separate boards.
Prototype1 had a backplane design where Video, Audio, and Input boards attached into slots perpendicular to the motherboard.
