From the project

Keyboards for Amstrad CPC Computers

This project is a keyboard suitable for direct connection to an Amstrad CPC. The PCB uses tactile switches which can easily be labelled with suitable legends for the keytops. The current layout is that of an Amstrad CPC6128, but the key matrix is the same across all machines. The only differences are in the connector types and pinouts.

This board has connectors which are compatible with: CPC464 with PCB keyboard (1x20 pin connector) CPC464 with membrane keyboard (2x10 pin connectors) CPC664 (1x20 pin connector) Untested CPC6128 (2x10 pin connectors)
