An emulator for various m68k and z80 based computers, written in Rust. Currently it has support for the Sega Genesis, TRS-80, and Computie (my own project), with Macintosh support in the works

transistor cb47d23233 Fixed issue with colour 0 being the mask colour 
For systems that legitimately use 0 for black, this causes a
problem, so I instead use 0xFFFFFFFF for the mask colour which
corresponds to transparent white in ARGB format, which minifb
doesn't support anyways

Moa

Started September 26, 2021

An emulator for m68k CPUs and devices. I originally started this project to distract myself while recovering from a bout of sickness. The idea was to emulate the computer I had built as part of the computie project.

Currently it can run the monitor program and load the kernel across serial (or the kernel can be loaded directly into memory), and it can boot the kernel. It opens two PTYs: one for the serial terminal, and one for the SLIP connection, and launches both pyserial-miniterm automatically connected to the console PTY, and launches slattach with the associated setup commands to create the SLIP device on the host, and set up routing.

There are currently peripheral emulators for the MC68681 dual serial port controller, and the ATA device, which loads the compact flash image on startup, which the OS can read.
