Ok, thats a wide (68 pin, not 80 pin, 80's are marked UW on the end 
I think) controller.  Chances are pretty good the tape is a 50 pin 
scsi-2 interface.  Assuming you are using some sort of an adaptor 
to go from 68 to 50, and that this adaptor properly terminates the 
upper 18 lines.  For the adaptor's terminations to function 
properly, it must have term power available on pin 26 of the cable.  
A minumum of 4.7 volts after the steering diode thats supposed to 
be on the 2940.

How close am I with the guessing so far?
