PDP-11 boards

I managed to grab a whole bunch of UNIBUS boards without knowing what they were today, and found out that they are basically the boards to an 11/40 CPU. Unforunately, I didn't see the rest of the CPU, or the M7237 board (is it an optional board?) or a backplane or... just the boards: M7231 KD11-A 11/40 data paths module M7232 KD11-A 11/40 micro word module M7233 KD11-A 11/40 IR decode module M7234 KD11-A 11/40 timing module M7235 KD11-A 11/40 processor status module M7236 KT11-D 11/40 memory management module M7238 KE11-E 11/40 EIS board M7239 KE11-F 11/40 FIS control Also I found a pair of 16KW _core_ memory cards (quad width). I separated one board, and the cores are IMHO absolutely beautiful. Two questions: 1) If I could find a backplane and powersuppl(ies), (and some peripheral stuff), is this enough to make a functional CPU? 2) Does anyone want this stuff? I want to definately keep one of the core memory boards, but the rest of it doesn't do me a whole lot of good. I'd like something interesting in trade or some money over shipping costs if so. I'm looking for a PDP-11/73 or -11/23 CPU to upgrade my LSI-11/2 :) along with memory for it (I have 8KW I think), and/or an RQDX1/2/3 or similar controller so I can attach some real (non-emulated) drives to it. I don't have anything to test these boards, so I can't verify that they work, of course, but they look in very good shape... no burn marks, oxidation, not much dust, etc. -- Pat
