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...
The P856/P857CPU uses a single PCB with a 74181 ALU and microcode in proms.
