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.

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.

Provides a bare recreation of the original Apple II Revision 0 motherboard for restoration or a ground-up build.

The bare board was in stock and backorderable on 2026-07-24. It does not include the required components, ROMs, DRAM, assembly labor, or bring-up work.

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.

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.

Combines a working Z80 or Z180 computer with RC2014-compatible expansion sockets on one buildable motherboard.

The official pages listed complete-kit and bare-PCB suppliers on 2026-07-27, but no assembled and tested option. Exact inventory varies by model and supplier; the Tindie seller was temporarily on a break when checked. Each board still needs assembly plus the documented power, terminal, and storage accessories.

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.

Programmed replacement ROM variants for diagnosing IBM PC, XT, and AT motherboard faults.

All three machine-family variants were listed in stock on 2026-07-25. Each replaces original motherboard ROM hardware temporarily; match the exact machine and sockets, observe chip orientation, and retain the original ROMs.

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.
