Z80 CPU Card for RC2014 (with clock and reset)

January 21, 2019

This is the Z80 CPU module I demonstrated a few months ago. It is designed to work with the RC2014 bus.

So what makes it special? Well, the module includes a number of extra features and enhancements designed to simplify a system build. These include:

It will work with either the standard RC2014 bus or the latest enhanced bus where all the Z80 CPU signals are available.

It includes several options for generating a signal clock: Crystal, Oscillator or taken from RC2014 back plane.

A reset circuit is included.

And the signals INT, NMI, BUSRQ and WAIT feature 10K pull-up resistors.

The schematic is here:
