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... P854. From what I rememebr it's got an 8X305
chip on it, which should
be easy to spot.
The card I suspect is the controller is labeled "5111 199 7817 CDD". The
cable that connects to the X1215 is labeled "X1215 CDD UP" on the top side.
The wires match up with the used contact fingers on the CDD board.
