Didier form aida.org was approached by his friend Erik about a malfunctioning MPS-65.
By studying the material on this page and doing measurements on the board it was decided the PROM on the board was malfunctioning.
So Didier designed a GAL replacement for the PROM and the board came back to life!
Here the story how the design looks like.
