The Multicomper motherboard is a simple platform for creating a 'Multicomp' computer based on the design work of Grant Searle - which can be found here:
http://zx80.netai.net/grant/Multicomp/index.html
The Multicomper holds all the components and connectors needed to create a Multicomp-based designs (Z80, 6809, 6502 etc.). The main part needed is a low-cost Cyclone II development board from your favourite auction site or other supplier - search for EP2C5T144C8N mini board, but do read the notes on the Github page below BEFORE ordering.
The Multicomper has the following additional features:
