I have a pretty rare chip that I need to write - 87C64, and the GQ-4X does not seem to support it at present. Can support be added for it?
Unlike 87C257, it does not have a transparent mode at all... I have an old original Willem programmer, and that one supports 87C256, but the presence of PGM (write strobe) pin seems to make any attempt at making an adapter impossible.
