Recreates an expandable Apple-1-compatible computer as either a compact single board or a set of functional cards on a backplane.

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.

Recreates the Apple-1 as a buildable 6502 computer with composite video, modern power, and PS/2, adapted USB, or ASCII keyboard input.

ReActiveMicro exposed assembled and kit selectors plus an Add to cart control on 2026-07-27. Supply a 1 A Micro USB power source, composite display, and compatible keyboard; USB keyboards require an adapter. The kit is intended for builders with intermediate soldering knowledge. Some systems powered by supplies with isolated grounds can suffer recurring slash characters and line feeds; the support wiki documents grounding, firmware, resistor, and capacitor remedies.
