6502-Retro

The 6502-Retro is a homebrew project that is inspired by the Z80-Retro! project by John Winans. See: https://github.com/z80-retro

There are various source code repositories in this org that can be divided into 3 main categories:

NOTE: The v4.3 hardware has 4 significant bugs

See the 6502-retro-v4 repo for details.

Hardware

  • 6502-retro-v3 This was the first version that supported a filesystem. It's been my development board for the last couple of years.
  • 6502-retro-v4 This is the next iteration of the board. It includes 2 expansion slots, a SPI bus and GPIO allowing for more experimentation with new hardware.
  • Expect to see some add-on cards for this board in future.

OS

  • bootloader A small rom resident program that will load the OS from the SDCard into memory and execute it.
  • rom monitor A monitor program that runs from ROM and can be started by the bootloader
  • 6502-retro-os The main operating system for the 6502-Retro!
