Subject: PDP 11-23 questions
I've found a PDP 11-23 computer oand I haven't
the foggiest idea
about it. What should I look for?
Claims to have:
M8044 DB
M8044 DB
Two 32KW memories, second rev 32kw, no parity. You can have
more of those up to 128KW (256KB)
M8186
11/23 KDF11A cpu if the handle has a C melted into it anywhere it's Q22
otherwise Q18 (assuming the second chip is there, the MMU).
M8013
M8014
RLV11 set, used for RL01 or RL02 removeable 14" 10mb disk.
M8029
RQDX21 interface for RX02. the is an
interface you need the
RX02 for a complete floppy system.
M8012 YA
diagnostic/Boot/terminator card, a must have with M8186
as the CPU has NO boot (it does have microODT).
there is a field guide for PDP11s! Also there is no serial IO
that you have listed. Typically a M8043 (DLV11J 4 port serial)
or a M8017 maybe an old M7940 both similar DLV11 type
single serial ports.
