I used it on both PDP-11/44 (RSX-11M+) and VAX/780 (VMS) systems
back in the early 1980s.   I even had to work on the VMS device
driver so that DECnet would work.

Unfortunately, I don't have any of the documentation or code from
those projects.   Just the memory that Field Service had a
terrible time adjusting the PCL bus timing so that they would
work.   Those wide cables were not pleasant to work with.

If you have any specific questions, it might jog some dusty bits
loose in my mind.
