MEK6802D3

I am aware of the following boards:

• MEK6802D3 Microcomputer Unit (schematic)
• MEK68R2M Programmable CRT Video Interface (manual)
• MEK68IO Input/Output Interface Board (manual)
• MEK68MM Memory Module
• MEK68RR ROM/RAM Module (manual)
• MEK68WW Wirewrap Module
• MEK68CC Card Cage

As far as I know the MEK6809D4 can also be used with these I/O boards.

MEK68IO

The two 24 pin sockets on the left are the I/O for the two PIAs. The unpopulated area on the top right hand side is for an MC68488 GPIB interface.
