Replaces an Apple II or II Plus motherboard with a complete Rev 7 RFI clone.

The current storefront exposed kit and assembled selectors on 2026-07-24. This changes an earlier Apple II to the later Rev 7 electrical and firmware configuration rather than preserving an original-revision board.

Rebuilds a Commodore 64 around a modern replacement motherboard with improved power, protection, video, diagnostics, and ROM switching.

CBMSTUFF marks the motherboard discontinued. Its product page, build manual, BOM, and supporting software remain online, and some optional parts remain listed. Used boards may occasionally appear on secondary markets.

Replacement bare PCB for rebuilding a Macintosh Classic whose original logic board is damaged.

The MacEffects page said Sold out on 2026-07-24. This is a bare replacement PCB, not a working logic board. No separate official Classic Reloaded BOM, placement package, donor-chip inventory, supported-revision list, or tested bring-up procedure was established. The Macintosh SE Reloaded discussion supplied during review concerns a different board.

Recreates the Macintosh IIfx logic board with new board files, schematics, a parts list, and rewritten PAL logic.

This is an advanced noncommercial board-build project, not an assembled product. The recreated PALs need suitable 16V8 or 20V8 devices. Low-power ATF16V8B parts do not work, and ATF16V8C parts may be problematic.

New replacement for the analog-board to logic-board signal cable in four compact Macintosh models.

The JCM page showed 17 units in stock on 2026-07-24. Never use the cable to combine an SE or SE/30 board with a Classic or Classic II board: the identical-looking connectors carry signals on different pins, and mixing the two groups will damage the computers.

Recreates the Macintosh LC 475 and Performa 475 logic board as a buildable replacement PCB.

This is an advanced noncommercial board-build project with no assembled purchase path. The repository warns that fabrication data was generated for JLCPCB and may need changes for other manufacturers.

Recreates the Macintosh Quadra 950 logic board with new fabrication and assembly data.

This is an advanced noncommercial board-build project with no assembled purchase path. Its Gerbers and placement data target JLCPCB and may need changes for another fabricator.

Provides a newly manufactured bare replacement PCB for rebuilding a damaged Macintosh SE logic board.

The authorized bare PCB was sold out on 2026-07-27. It includes no populated components and is an advanced board-level rebuild. The best public follow-up found was a maker-authored TinkerDifferent discussion, but no complete official BOM, placement package, donor-chip list, supported original-board revisions, or tested bring-up procedure was established.

Redesigns the SE/30 logic board as a buildable replacement with Gerbers, placement data, a BOM, and recreated programmable logic.

This is a fabrication package, not an assembled order path. The published Gerbers were generated for JLCPCB and may need adjustment for another fabricator. Low-power ATF16V8B programmable-logic parts do not work, and ATF16V8C parts may also cause problems. The build still depends on Apple custom ICs sourced from donor hardware.
