The M8047-CA is aka MXV11-CA.

RS-232.

Thanks...although I thought it was MXV11-AC....

Thanks very much. Anyone have any further doc on these (apart from the
drawings)?

The MXV11 module is described in the:

EK-LSIFS-SV-005-III LSI-11 Systems Service Manual Volume III

which is available at:

http://vt100.net/mirror/antonio/ek-l...v-005-vol3.pdf

and in the:

DEC Microcomputers and Memories Handbook EB-18451-20

which doesn't seem to be available online yet.
(Anyone out there willing to provide a scan of it?)

Thanks! I did search vt100.net but was too specific, searching only for
the option and module numbers.

Sorry, you're right about the suffix. http://world.std.com/~mbg/pdp11-field-guide.txt
lists only -AC, but http://www.fpns.net/willy/pdp11/BOARDS.HTM
mentions both -AC and -CA.

"Microcomputers and Memories" describes the -AC is described along
with the -A. Three versions of it are downloadable from
http://www.computer.museum.uq.edu.au/documents.html which also has
configuration pages from the MXV11-AA manual.

Yes, just saw that in the Systems Service manual.

Will take a look.

Then I have to sort out all the other stuff, get the muck out of this
machine and try to make it go. Years since I used a PDP-11 - my first
was an 11/20 in 1974...!
