PRINTED CIRCUIT BOARDS (PCBs) *Index*

 

I have provided designs for a Z80 system using 3 different buses.

Because of the changes to the backplane for each system, the CPU board and its expansion boards are only compatible within each system family:

1) M62: 62-pin IBMPC 8-bit expansion card type of connector

2) ZB64PC: 64-pin IBMPC 8-bit expansion card type of connector

3) ZB64EC:L 64-pin Eurocard expansion type of connector

ZB64PC-bus Z80 SBC System
ZB64EC-bus Z80 Multi-board Computer (MBC) System
VGA/PS2 Keybd Bd.
