Builds a PET 4032-compatible mainboard from modular CS/A65 processor, PET I/O, and video cards.

No assembled seller or current PCB supplier was verified. A build needs three or four CS/A65 cards, a backplane, components, a programmed ROM, a case, a display or video-interface circuit, and a power supply. PETCPU revision 1.1B publishes board files but its layout is marked untested; the current VDC and PETIO pages publish later revisions marked okay, while the replica instructions date from 2010.

Recreates several Commodore PET models on a modern single board with a faster 65816, expanded memory, color VGA graphics, USB input, and SD storage.

No current assembled seller was verified. Revision 3.0A has public GPL-3.0 hardware files, but it is an advanced build with fine-pitch surface-mount parts, separately programmed FPGA and boot firmware, and dependencies across several repositories. The family documentation warns that boards, bills of materials, and firmware are moving to newer video timing and says to contact the maker before building.

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.

Builds an integrated modern PET-compatible computer with selectable PET models, accelerated operation, enhanced color video, storage, audio, and current input.

No current assembled seller was verified. Revision 1.3A has public GPL-3.0 hardware files, but a build requires fine-pitch surface-mount assembly, separate FPGA and ROM projects, and programmed devices. The family documentation warns that boards, bills of materials, and firmware are moving to newer video timing and says to contact the maker before building.
