From the project
Video adapter for connecting an Amstrad PC1640 to an Amstrad PC-MM monochrome monitor
Video adapter for connecting an Amstrad PC1640 to an Amstrad PC-MM monochrome monitor.
The PC1640 and PC-MM were never designed to work together — the PC-MM was built for the PC1512. This project documents the signal incompatibilities and presents four adapter designs to bridge them.
Solutions: Run PC1640 in CGA mode (SW8 = OFF) for simplest adapter, or keep EGA mode (SW8 = ON) with additional signal conversion. See options below.
