OK, done; see:

What did the problem turn out to be (or is this a different one)?
If the latter, do you have any use for a 5-instruction 'scope loop program
which sends characters continuously, which you can toggle in, to

nice DEC branded version so I went through the pin assignment fun then.
Update: I now have both a working DL11-W (M7856) and an DL11 (M7800) who
connect to my terminal through the DEC cable with part number BC03L-10. I
have loaded PDPGUI program so I can test things, etc.

Tony,
Thanks for the tips. The card may have bad component(s) but at least it
had not yet been previously repaired when the unit was in production. I
find "vintage" repairs from back in their day ar

Well, DL11's long predate TU58's, and the 'first' DL11 would almost certainly
have been connected to a terminal, but yes, basically.

I'm sure I would have - I, like a lot of others, struggled with the
address/vector jumper

Got it; that would mean you're wanting the standard console.

I intend to use a serial terminal to access the console via M912 CONSOLE
ROM. I believe you're saying to connect A7/A3 and V4/V5, but I still don't
understand the pattern.
What would A4, A5, A6 and V7, V6, V3 represe

Yeah, but look at it this way: their being inverted can be a memory jogger -
'Oh, the DL11, that effed-up interface where the jumper sense is inverted
between address and vector!' Then you only have to look up one of the two.. :-)

Does anyone have a M7800 (DL11) set for 9600 b N71 or N81 jumper'd with the
default address for use as a serial terminal interface? I understand the
other jumpers on the card, but the address and vector jumpers confuse me.
