====== G8PPBase + Z80 ======

===== Introduction =====

This is a two-board configuration consists of a [[builderpages:plasmo:g8pp:g8ppbase|G8PP in baseline configuration]] and a simple Z80 board on RC2014 backplane.

===== RC2014 Signal Definition =====

The predefined RC2014 signals remain the same. The spare signals are connected to the following Z80 signals:

RC2014 Pin 37 (Spare 1) — nBUSRQ (Z80 pin 25)

RC2014 Pin 38 (Spare 2) — nWAIT (Z80 pin 24)

RC2014 Pin 39 (Spare 3) — nNMI (Z80 pin 17)
