z80ctrl is an AVR-based bootloader, debugger, and I/O device for a Z80 retrocomputer with the following features:

  • Runs CP/M software including WordStar, Zork, Ladder, Turbo Pascal and more!
  • Plug-in module for RC2014 retrocomputer replaces the clock, serial, ROM, and CF boards
  • Reads HEX files and disk images from a FAT32-formatted SD Card
  • Provides Altair and RC2014-compatible serial port
  • Compatible with unmodified Altair disk images from the SIMH emulator project
  • Monitor with memory inspector and built-in Z80 disassembler
  • Single-step debugging, breakpoints, and watchpoints to trace Z80 bus activity in real-time
  • Flexible MIT-licensed firmware can be the basis of your own SBC or breadboard computer
  • Expandable SPI bus allows bridging other SPI peripherals to the Z80

I have made a series of videos demonstrating the design and features of the system.

Have a look at the topics on the right, especially the [Board Assembly Guide] and [Monitor User Guide].
