SC/MP chip emulation on PIC16F877
As promised in the vintage computer section, here's details of the SC/MP emulation I've implemented on a PIC microcontroller. It is not a true chip-level emulation: many bus signals are missing and those that are present don't necessarily conform to SC/MP datasheet timing. So it's useless for insertion into classic machines like the Scrumpi, Mk14 etc,
But I have built myself a NIBL machine using the emulator. I'm using it to develop some useful routines to go in page 2, e.g. an assembler. Note that the PIC source code is presented as a text file to get around forum restrictions. Last edited by Karen O; 2nd Jun 2020 at 9:49 pm. Reason: Typographical error |
