AFAIK, the connectors for a DLV11-J are 2x7-way... There are only nine
pins (one is missing for keying), but the extra bits help you center
the connector. 2x5 will work, if you don't miss.
You can still get them, but the pins are horrendously
expensive in small
quantities.
No kidding. One other "problem" is that you need to stock one set of
pins for small connectors (like the DLV11-J) and another set of pins
for large connectors (like an RL8A - 40 pins) because there are different
mating forces. Yes, you can use the "wrong" pins, but they were spec'ed
different for a reason. "Weak" pins in a small connector might not
grab enough to stay in well enough, and "strong" pins in a large connector
might be too difficult to insert.
Given that mostly, I need to make serial cables (BC01V for the PDP-8,
as well as DLV11-J-style PDP-11 cables), I need to find a source of
"weak" pins that is less than 2/$1.00. Fortunately, I have the crimper.
For small quantities of cables, I still recommend the IDC connectors.
