Two lists of the board model numbers that make up complete CPU sets for various Prime machines. I posted this to comp.sys.prime at one point.
Thatching old paper files today, I've come across some interesting things I'd forgotten I had. Among them are a photocopy of a three-page list on Prime field office stationery of Prime board revisions current as of 11/1/86 which includes a blow by blow listing of which boards comprise the CPU set for each machine type released at that point; and an unlabeled single-page photocopy listing the CPU sets without revision info. The two documents seem to differ slightly. Below are the CPU set bits; if anyone wants the revision information for other boards and power supplies, just ask. Enjoy.

The "360" listed above shows the part number for the floating point board. The base single board CPU is apparently a 2223-360. Thanks to James Cosper for this info, based on having worked with P300 machines, and having the build sheet for one circa 1975. ----------- Andrew Schwartz on c.s.p. 3/13/98: "I believe that this is an E board from a 6350/6550. Peter said that the number was PCD10068-001. I think that he meant PCB10068-001 which is the part number for the PCB for the E board, model number TLA10095-001 or TLA10274-001."
