Design, documentation and software for the Really Old School Computer (6502)

This repository holds design files, firmware and software for the Really Old-School Computer (6502) single-board computer, AKA the rosco_6502. This is a fully-featured, programmable, extensible and capable 8-bit retro computer that is completely open source and will be available in kit form (coming soon).

The rosco6502 is the "little brother" of the popular roscom68k m68k computer. It is made by the same people, and shares the ethos of being powerful, extensible and above all, fun.
