There are no operational differences that you'll notice between
a DEQNA and a DELQA cabinet kit if you're using a PDP-11.
There are two extra signal lines on the DELQA vs DEQNA cables,
which correspond to "Control in, circuit "A", and "B".
The purpose of these, I'm not sure; maybe some sort
of throttling or flow control. I doubt the PDP-11 driver
uses it. Not so sure about the MicroVax.
For basic operations, with a DEQNA-compatible driver,
the cables should perform identically, as they are
pin-compatible.
