Ongoing excavations - PDP-11/20 bits

For those at home who have been following my relocation of stuff from the basement of my former boss, I have *located* the 11/20 chassis. It has some backplanes in it but no power supply. It is sitting on a BA-11 that looks suspiciously of the same era, but too far down in the stack to get at just yet. If so, then I have a CPU bay and two BA-11 expansion boxes, enough FLIP-CHIPs to probably reassemble the CPU, several sets of 4K MM11-E boards (at least one core plane is in the hands of a former cow-orker, now in Boston), two power supplies total, a diode-matrix boot board, several peripheral cards and plenty of modern stuff to make this thing boot. I do also happen to have the original 1970 PDP-11 handbook that came with it, but no prints. Does anyone have a module layout for the 11/20? BTW, since this has come up recently, from the handbook, page viii The PDP-11 is available in two versions -- PDP-11/0 and PDP- 11/20. The basic PDP-10 contains 1,024 words of read-only memory inconjuction with 128 words of read/write memory and the basic PDP-11/20 includes 4,096 words of read/write memory I take it that the -11/20 has an MM11-E backplane in the CPU box and that the -11/10 comes with an MR11-A braided core ROM unit and an MW11-A "Wordlet" core board. After this is entirely excavated, I would expect that I could use an additional H720 PSU, but since I have the specs (+5V @ 12A, -15V @ 10A, +8RMS (unreg) @ 1.5A, -22V (unreg) @ 1.0A) that I could fake it with modern equivalents. -ethan ===== Infinet has been sold.
