They're DL11s, and depending on the link settings
and the chips fitted,
they're either current loop or RS232 ports (using the standard-ish DEC
cables). They're pretty dumb interrupt-on-a-character ports, but they're
easy to program and work. And yes, they're general purpose ports.
Neat, sort of like the original PDP-8 serial port. :-)
Only thing is, I thought the DR11-W was a hex card..
I can go check the handle, the card is definitely quad as its in the same
row as the bus jumper.
I'm almost sure it's actually a DR11-B.
You correctly identified it. I moved a few of the white handled things and
all the cards you mentioned are in there. So it is a DR-11B.
Thanks Tony! Lots of good info. I can't wait to start the check out to get
it fired up...
