Rebuilds an Atari 800XL around a newly manufactured Revision 1.2 motherboard with bare, programmed-chip, and assembled options.

The main board page reported two units in stock on 2026-07-27. A completed board requires the buyer to send a functional, non-returnable donor board because original Atari chips and some connectors are no longer made; the seller estimates about two weeks for completion and testing after receiving it. The separately orderable programmed-chip page reported four sets in stock. Its EMMU must match the intended memory configuration and is optional for a 64 KB-only build.

Open 68060 processor card for Amiga 3000 and 4000 computers.

AMIGAstore warned that only the last assembled units remained on 2026-07-24. Rabbit Hole Computing's bare PCB listing was sold out. Building from the GPL-licensed project files is an advanced assembly requiring the processor, programmed logic, connectors, and the rest of the bill of materials.

Rebuilds the electronics inside an original Disk II drive with a cleaner analog path, keyed cabling, write protection, and easier head access.

CT6502 offered the two-board set for direct ordering on 2026-07-24. The boards are not sold separately.

Packages a Raspberry Pi 3B+ and RP2040 keyboard interface into an original C64 or C64C case as a low-latency BMC64 system.

Current shortboard and longboard v4.0 files and an easier-to-assemble v4.0.1A variant were available on 2026-07-27. No assembled seller was verified. A complete build needs both PCBs, components, assembly, a Raspberry Pi 3B+, Waveshare RP2040-Zero, microSD card, original C64 or Mechboard64 keyboard, suitable case, and power. BMC64 itself is not compatible with Raspberry Pi 4B or 5.

Rebuilds a Commodore 64 around a preassembled replacement motherboard with automatic chip configuration, static RAM, flash ROM, and dual-SID support.

Individual Computers marked the board available for immediate delivery on 2026-07-27. It is not a complete computer: the key CPU, port, sound, and video chips are not included. The product page still uses some preproduction or older photographs, so physical appearance can differ.

Assembled replica controller board for building a Commodore 1581-compatible 3.5-inch disk drive.

Retro Electronics listed the fully assembled and tested board out of stock on 2026-07-25. Only the controller PCB is supplied.

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.

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.

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.

Replaces a failed Commodore PET motherboard with a modern 32 KB board supporting selectable 40- and 80-column modes, several BASIC versions, and original PET interfaces.

Tynemouth Software's active Tindie listing offered revision 1.84B as either a through-hole self-assembly kit or a built and tested board on 2026-07-27. International buyers are instructed to contact the seller for a shipping quote.

Bare replica motherboards for rebuilding damaged Commodore 64 boards in four original assembly configurations.

Bob's Bits listed the bare SixtyClone PCB at USD 35 on 2026-07-30 with live revision and optional-component controls. The Tindie page simultaneously displayed a United States shipping rate and a does-not-ship warning, so confirm destination availability before ordering. Resistor, capacitor, resistor-network, power-switch, SwinSID Nano b, and GAL-PLA options do not make the base board a complete computer.

Provides new bare analog and neck-board PCBs for rebuilding a Macintosh SE display and power assembly.

The product page offered Add to Cart on 2026-07-24. The listing supplies only bare analog and neck PCBs. There are no assembly or soldering instructions, and the vendor assumes expert high-voltage experience. CRT and mains circuitry can retain lethal voltage; this is not a beginner repair.

Replaces the ball mechanism in an original Apple ADB Mouse or ADB Mouse II with an adjustable optical sensor while retaining the ADB interface.

Both $72.99 variants were out of stock on 2026-07-27: the Mouse II board since May 25 and the original wedge board since July 18. Match the replacement to the exact shell and board shape before ordering. The original ADB cable is required, and installation may require moving its four wires or connector. The USB-C connector changes settings and firmware; it does not turn the mouse into a USB device.

Replaces a Commodore 64 motherboard with an FPGA-based board offering modern video, storage, networking, and emulated peripheral functions.

The official store still listed the Ultimate64 Elite-II out of stock on 2026-07-27. Its home page says the black short-board run is sold out and Commodore has taken over sales of its version of the board. Check both current vendors rather than assuming another 1541 Ultimate batch.

Experimental C64 replacement motherboard with three SID sockets, optional internal storage and sound modules, ROM switching, and extensive test points.

On 2026-07-30, UNI64 listed the bare v4 PCB at EUR 32.50 as a three-week preorder and the READY+ board at EUR 345 with a five-week order lead time. READY+ includes standard logic, the 8701, and 64 KB RAM but excludes all named Commodore-specific chips and the required 12 VDC 2 A supply with a 2.1 mm inner-diameter barrel plug. Optional Pi1541, MIDI, FM OPL2, and SSD hardware is not included. The bare page labels its feature list as Version 3 even though the product and files are v4; the linked v4 info PDF remained unreadable after the required retry under WF-071, so confirm version-specific assembly details from the supplied documentation.

Bare replica of the later seven-pin-power VIC-20 Assembly 250403 motherboard.

Bob's Bits listed the bare Vicky Twenty PCB at USD 35 on 2026-07-30 with a live color selector and optional resistor, capacitor, and power-switch controls. The page exposed no destination-specific shipping decision until a country is selected. The base product is an unpopulated board; none of the optional packs supplies every component or custom chip required for a working VIC-20.
