<a M9192? The list I have shows it as being a "DUAL HEIGHT CPU BRD", whic
<is "real" informative! According to the list I've got the 23's CPU's hav
<different numbers.
M8186 PDP-11/23 (KDF11A)
M8189 PDP-11/23 (KDF11B)

<They both have 256KW of 18-bit memory. This brings up an interesting
<question, how many bytes are there in in a Word when you're talking
<PDP-11's? Since it's 18 my guess would be 2 with parity bits.
Correct the extra are parity and it's always 2 8bit bytes to a 16bit word.
<SCD-RQD11/EC -- this one had 6 connectors for ribbon cables
I believe this is a distribution board for the RQDX1/2/3 floppy/hard disk
controllers.
<M8059-KP -- I believe it's 64k, is it for PDP?
256kb(128kw) parity memory.
<M3104 DHV11 -- It's got two ribbon connectors, by guess is it's for addi
<other terminals. I seem to have a pair.
These are terminal line controllers with silos and modem controls. Handy!
<Distributed Logic Corp. DQ342 -- no idea, two ribbon connectors
Unknown to me.
<Plessey P/N 70590-100A -- looks to be a RAM board
There were a lot of third part ram suppliers.
