From the project
65C02 Microcomputer
The n8 Bit Microcomputer is a homebrew breadboard computer built around a WDC65C02 8-bit CPU. If you are looking for the software that runs on this computer, check out LmaOS.
The n8 Bit was originally a breadboard computer based on the Ben Eater series of 6502 videos but with some added capabilities including ACIA support, GAL-based address decoding logic, and a power chip for more reliable reset and power-on. Since then, PCBs have been printed and development around the computer is based on these.
