For this compatible system (exact system): This is the compatible system itself. The project calls it a fully functional Apple-1 replica and supplies WozMon and BASIC firmware. Its default Arduino Nano serial interface replaces the original computer's discrete video and physical-keyboard circuits, so builders seeking a closer hardware interface should evaluate the optional VDU and input modules. The GPL-3.0 repository supplies KiCad design files, fabrication exports, schematics, bills of materials, firmware, and assembly guidance. Builders must fabricate boards, source components, solder the computer, program its EEPROM, and load the Arduino Nano interface software. Retro Electronics had one bare backplane PCB, three bare VDU PCBs, and five bare VDU color-amplifier PCBs in stock on 2026-07-27; these are parts of the RC6502 build and do not constitute a complete kit. Early SBC revisions D and E need the documented CPU-power patch wire; the repository's current bill of materials names Revision H.
