The Z80MPU is a complete Z80-based microcomputer on a board of the exact size of a credit card. It has all signals available on standard 2.54mm pitch pads along the two longer sides of the board to give the designer freedom for his/her application. Together with the Z80-CPU there are 64kB static RAM, one KIO (2 UARTS, 3 parallel ports, 4 timers) and a socket for a 32kB EPROM (PLCC) that is enabled for all READ accesses in the lower half of the address space and switched off by the first IN/OUT-instruction. This feature allows the bootstrap from the power hungry EPROM, but running off the more power preserving RAM, making the board especially usable in portable applications.
