Yes. I made the comment because I'm more confident about the condition
of the older board than the newer board.

Sorry... I wasn't paying attention. Aaron and David have been most
helpful to me over the years, directly and indirectly. I wouldn't
want them to think that I was giving credit to someone else. Thanks
guys!

I don't deserve any
credit for the tapes and docs online -- they're the
fruits of serveral other people's labours :-) pdp8.org is Aaron Nabil's
site, and David Gesswien provides the docs at www.pdp8.net At the moment,
I think I have an M865 that works and an M8650 that may
or may not work.
You probably know you can use an M8650 in RS232 mode. How different is an M865? Is it only current-loop?
It is different. There is no 40-pin BERG connector - it has a set of
split lugs line a W-076 card and a 18" cable with a standard Mate-n-Lok
connector as seen on KSR-33s and VT220s, etc. I do not recall if I have
any docs on it, but except for the 20mA/EIA differences, I think it's
substantially similar, logically, to the M8650. It's a console port,
only, permanently set to 03/04. I forget if the M8650 is modifyable or
not.
