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)

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.
Cheers,
