====== A2CPLD, An Apple II CPLD Board for Hosting Coprocessor ======

===== Introduction =====

A2CPLD is a prototyping platform to develop coprocessor for Apple II. The 40-pin DIP is wired for Z80. However, nested in the 40-pin DIP is a 48-pin DIP that is not wired, but can accommodate other 40/48-pin retro processor and reroute Z80's address/data/control signals to the uncommitted DIP socket.
