RE: Casio 4bit SRAM replacement project
TRS-80 PC-4 (Casio PB-100): The PIC is successfully pretending to be a 1K RAM module! The code is a total mess but now that it works it can be cleaned up. I think with this PC-4's firmware it might be able to handle more RAM as after finding DEV1 it tries to find DEV2.
