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!

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

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.
