P800 boards

I've completed a list of boards in the P800 haul: CPU BOX 1 - labeled P859 . CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859) . MCU3 : 5111 199 77442 (Paper tape, serial control unit (partially populated)) . 2 x M128E : 5111 199 67592 (128Kx21 RAM) . MCU2 : 5111 199 78181 (Line printer, card reader control unit) . MTCU : 5111 199 72467 (Pertec 9 track magnetic tape control unit) . 2 x M128ES : 5111 199 58622 (128Kx21 RAM) . MCU3 : 5111 199 77444 (Paper tape, serial control unit (partially populated)) . AMA-8A : 5111 199 75318 (Asynchronous line multiplexer) . SLCU2 : 5111 199 69373 (Synchronous serial line control unit) CPU BOX 2 - labeled P859 . 2 x CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859) . M128E : 5111 199 67592 (128Kx21 RAM) . MCU2 : 5111 199 78185 (Line printer, card reader control unit) . MCU2 : 5111 199 78186 (Line printer, card reader control unit) . MCU3 : 5111 199 77445 (Paper tape, serial control unit (partially populated)) . BIGD : 5111 199 73289 (Big disk (40/80MB CDC) controller) . BIGD2A : 5111 199 57852 (Big disk) The weirdness of Box 2 is - obviously - a second CPU in the same box. This can't be right. CPU BOX 3 - labeled P859 . CP7R : 5111 199 67589 (P857R CPU for P858,P859) . M128E : 5111 199 67593 (128Kx21 RAM) . TIMER CARD : 4022 422 20091 . ? : 4522 107 62304 . CU-ADIOS : 8222 255 50942 Box 3 has three cards with part numbers in different series from the normal 5111 199 xxxxx CPU BOX 4 - unlabeled, P856 type M4M box . 2 x CDD : 5111 199 78176 . CDD : 5111 199 78177 . CDD : 5111 199 78178 . 2 x MCU3 : 5111 199 78198 (Paper tape, serial control unit fully populated)) . MMU : 5111 199 75183 (Memory Management Unit) . GPC : 5111 199 79382 (Custom card) Box 4 just looks wrong. I don't know what the CDD cards are, but there doesn't appear to be a CPU or memory in there. However, there are P856 CPU's in the spare cards box, and I found references to the P856 being able to use MOS memory as well as core, so all might not be lost here. EXPANSION BOX - E2 type (6 slots) . BIGD2A : 5111 199 57852 (Big disk) . MTCU : 5111 199 72467 (Pertec 9 track magnetic tape control unit) . BIGD : 5111 199 59755 (Big disk (40/80MB CDC) controller) . MTCU : 5111 199 72462 (Pertec 9 track magnetic tape control unit) . 2 x MX : 5111 199 79335 CASSETTE BOX - P833 . K7S2 : 5111 199 79329 (P833-152 Cassette Control Unit) Combined with the spare M-format cards in the haul, the complete list of boards is as follows: . ? : 4522 107 62304 . AMA-8A : 5111 199 75318 (Asynchronous line multiplexer) . BIGD : 5111 199 59755 (Big disk (40/80MB CDC) controller) . BIGD : 5111 199 73289 (Big disk (40/80MB CDC) controller) . 2 x BIGD2A : 5111 199 57852 (Big disk) . 4 x CDD : 5111 199 7817X . 2 x CP7R : 5111 199 67589 (P857R CPU for P858,P859) . 3 x CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859) . CPB : 5111 199 74979 (P856 CPU) . CPB : 5111 199 76227 (P856 CPU?) . CPB / CP7B : 5111 199 63142 (P856 CPU?) . CU-ADIOS : 8222 255 50942 . 4 x F1MB : 5111 199 6742X (modified for 5.25" FDD) . 3 x F1MB : 5111 199 67427 (8" Floppy disk controller) . F1MBY : 5111 199 58742 (Floppy disk controller) . FLDB : 5111 199 69667 . GPC : 5111 199 79382 (Custom card) . 2 x IOP : 5111 199 73185 (I/O Processor) . K7S2 : 5111 199 79329 (P833-152 Cassette Control Unit) . 5 x M128E : 5111 199 6759X (128Kx21 RAM) . 2 x M128ES : 5111 199 58622 (128Kx21 RAM) . 3 x MCU2 : 5111 199 7818X (Line printer, card reader control unit) . 5 x MCU3 : 5111 199 7744X (Paper tape, serial control unit (partially populated)) . 2 x MCU3 : 5111 199 78198 (Paper tape, serial control unit fully populated)) . MMU : 5111 199 75183 (Memory Management Unit) . 3 x MTCU : 5111 199 7246X (Pertec 9 track magnetic tape control unit) . 2 x MX : 5111 199 79335 . SLCU2 : 5111 199 69373 (Synchronous serial line control unit) . TIMER CARD : 4022 422 20091 Looks like I should be able to get a few systems going with these parts. There's also a second box with spare cards, having different formats. Some of these are double eurocard format, like those used in the P85xE systems. There's also a spare power supply for a P859 box, as well as a spare power supply for a P856 box. I'm interested in finding out more about the cards I couldn't identify, these are: . ? : 4522 107 62304 . 4 x CDD : 5111 199 7817X . FLDB : 5111 199 69667 . 2 x MX : 5111 199 79335 . TIMER CARD : 4022 422 20091 I'm hoping CDD means Cartridge Disc Drive, and that these are the controllers for the X1215 disk drives. The 2 8" floppy disk drives are CDC BR8A8A type, looks like they are 800KB double sided, double density drives. They're very dusty.
