The computer with only COSMAC CDP1802 and PIC18F47Q43/PIC18F27Q43
developed by Kazuhiro Ouchi
The purpose of this experiment is to see if it is possible to make a real COSMAC work with fewer components, at a lower cost, and more compactly.
The EMU1802 is replacement the CPU of the EMUZ80 with a COSMAC.
The EMU1802-mini is replacement the PIC of the EMU1802 with a PIC18F27Q43.
