From the project
AVR-based bootloader, I/O, and debugging for Z80-based computers
z80ctrl is an AVR-based bootloader, debugger, and I/O device for a Z80 retrocomputer with the following features:
- Plug-in module for RC2014 retrocomputer replaces the clock, serial, ROM, and CF boards - Runs CP/M software directly from FAT32-formatted SD Card - Boots unmodified disk images from the AltairZ80 emulator - Monitor with file management, memory inspector, and built-in Z80 disassembler - Single-step debugging, breakpoints, and watchpoints to trace Z80 bus activity in real-time - Expandable SPI bus allows bridging other SPI peripherals to the Z80 - Flexible MIT-licensed firmware…
