I've got a serial line interface in this LSI 11/23 system I've got here.
It's made by MDB Systems and is model DLV11J. I've got the manual for the
DLV11 but it gives the digram for one big 40 pin Berg style connector,
whereas the DLV11J has 4 10-pin Berg style connectors.
Does anyone have the documentation for this?
And now for a really stupid question:
Can the 11/23 run RT-11?
Thanks!

Yes. It runs RT-11 very well.

Normally, a DLV11-J also has the four 10pin connectors. The cable that
goes between them is a ribbon with a 40pin IDC at one end and 4 x 10pin
IDCs at the other, wired such that the first 10pin is on the second
connector's pins 1-10, the next on 11-20, the third on 21-30, and the
fourth on 31-40.
That should be simple enough, right? : )

Right. That's the card I have (DLV11-J). I have the manual for the
DLV11, which describes the 40-pin connector.

Right, but then what the hell am I supposed to do with a 40-pin IDC? :)
I need to convert that to something sane. I.E. a DA9 or DB25.
So the next question is, what are the pinouts?

But a plain DLV11 is a single-line interface (like a DL11) and has a
single 40 pin Berg header. I suspect that's the pinotu Sellam has.
I would try to find the DLV11-J manual (the DEC one), which has 4 10 pin
Berg headers. If you can't find it, I'll see what I can do.

At the risk of being wrong, but we did a fair bit of this once upon a time.
The pin out of DEC 10p RS232 console ports were common across DRV11J, KXT11
& KXJ11 boards. The pin out of MDB JFEP-SLU RS232 ports were the same, we
used common test leads. Very probably an MDB DRV11J uses the same pin out.
The cookery for a DEC DRV11J null modem lead, taken from the 1980
Microcomputer Interfaces handbook, follows:
pin connection
1 uart clock in or out N/C
2 signal ground RS232 pin 5(D9)/7(D25)
3 Tx Data + RS232 p2
4 Tx Data - N/C
5 signal ground N/C
6 Indexing pin - no key N/C
7 Rx Data - connect to p9 (ref signal for diffl rcvr)
8 Rx Data + RS232 p3
9 signal ground connect to p7
10 +12V, with F1 installed N/C
NB link p7 to p9 and adjust 2/3 twists and connecter gender to taste.
