SC103, v1.0, Description

The final installment in my set of three Z80 peripheral chip modules designed for RC2014.

This module houses a Z80 PIO chip and provides two 8-bit I/O ports with handshaking.

Complete 1

The main features of this module are:

  • Full Z80 mode 2 interrupt support (IEI/IEO daisy-chain)
  • Tight address decoding
  • DIP switch address selection
  • Two 8-bit I/O ports with handshaking
  • Connector on rear edge for ribbon cable
  • Connector on top edge suitable for Dupont cable

My first application of the PIO module application is a simple alphanumeric LCD interface.
