I built this board when building up my retro 1 6502 computer. It wires up a WDC 65C02, 32K ROM, 32K RAM, and an oscillator. This pcb helped to ensure these common components were wired securely and correctly and decreased the amount of wiring needed on the breadboard. The board has all of the 65C02 pins broken out into headers as well as headers for the control pins of the RAM/ROM chips. I used my Power Pod project to provide the 5v power input.
