Macintosh 128K Replica Board

The original Macintosh shipped in January 1984 with a 68000 CPU, 128 KB of RAM, and the first commercial GUI on a consumer machine. We reproduce the original logic board on its original layout — drop-in compatible with vintage 128K, 512K, and Plus cases.

Frequently asked

Macintosh 128K Replica Board — questions answered

Will this fit in my Macintosh Plus case?

Yes — the 128K, 512K, 512Ke, and Plus all use the same compact case and analog board. The mounting holes and connectors are identical.

Why so little RAM compared to the 512K board?

Historical fidelity. If you want more RAM, choose the Macintosh 512K or Macintosh Plus reproduction — same compact form factor.

Built to outlast you.

Every board is hand-soldered by Logan in a Fresno workshop, period-correct components where available, and shipped with a numbered certificate of authenticity.
