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.
