This module houses a Z80 parallel input/output (PIO) device (Z84C20xxPEG) and is designed for use with the RC2014 retro computer.
The Z80 PIO provides two 8-bit ports, each with handshaking and interrupt capabilities.
The parallel I/O signals are available on a row of header pins on the top edge of the board, and also a double row of pins on the rear edge of the board. The pins on the top are easy to connect to solderless breadboards via dupont cables, while the connector on the rear edge is suitable for connection with a ribbon cable.
The module provides support for Z80 mode 2 interrupts, with the IEI and IEO signals available on a two pin header for linking with flying cables. These signals can also be optionally connected to the RC2014 bus with jumpers. Address selection is by DIP switch, allowing the module to be located on any 4-byte I/O address boundary. The tight and flexible address decoding means many of these modules can be fitted to a single RC2014 computer.
