D4289 Memory-I/O Controller: Handles reading of program in the 28C64 and interfacing to output/inputs
ZIF sockets:1 16-pin ZIP for 4004 processors, 1 16-pin ZIP for 4002-x RAMs and one 24-pin ZIP for 4040 processors.

Nylon Stand-offs: Allow the board to be set safely on your workplace/desk.
Mini-USB Cable: For Powering the test board
The board requires a single +5V power supply (350mA) provided through a mini-USB connector. The board contains the DC-DC converters needed for providing the -5V and +15V power required by the CPU. Power can be supplied by a typical USB wall-charger or even the USB port on most computers.
There is a power failure indicator and protection circuit implemented on the board.
Address, data, control and INT lines are available, so that the board may be used for other projects or testing purposes.
Note: The 4004 4002 and 4040 are NOT included in the auction, just the test board and cable
