Amstrad Expansion System aka Maplin ROM Card

Amstrad Expansion System

The Amstrad Expansion System is a DIY project by Dave Goodman and John Attfield.

The Amstrad Expansion System was primarily a rom box for the CPC series, but had additional features:

  • 128 - 8bit I/O port.
  • Motherboard extension plug for EURO-card modules.

The DIY project consisted of a 16 page instruction leaflet.
