Sure of this ?
My P856 ( 12nc 5111 100 05701 ) and P857 ( 12nc 5111 100 05702 ) CPU boards
definitely have 4 x74181 datapath, and 6 x 82s115 PROM microcode.
That would mean Philips reimplemented the same CPU twice.
Somehow it does not surprise me...
My MCU3 boards also have a different 12nc number compared to yours. ( 5111 100 05582 )
. 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... This card has 178 14 and 16 pin chips on it, all 74xx
logic except for four that are marked "F 9301 DC"
F9301 is also TTL , from Fairchild 1 - 10 decoder
If your documents list a LSM16 board, I'd like to know what it is. That's a
mystery board I have .
