. 2 x CP7R : 5111 199 67589 (P857R CPU for
P858,P859)
. 3 x CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859)
What technology does this CPU use? 2900 bit-slice, ASICs, or what? The
P854 CPU is 3 cards, I think, one of which is the MMU (and one of the
others an IOP?, I would have to check the manuals). The P851 CPU is a
signle board, using Philips bitslice ICs...
. 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))
You might find the P851 tech mnaul Vol 2 is useful here.
I'm hoping CDD means Cartridge Disc Drive, and
that these are the
controllers for the X1215 disk drives.
Althoguh I don't have the drive, I think I have the X1215 controlelr in
my P854. From what I rememebr it's got an 8X305 chip on it, which should
be easy to spot.
