Hi Pontus,
I looked at my limited function front panels, and they were 54-11507s. I
have not looked at any prints. Where did you find the 54-11165 number?
Could it be for a Q-bus system?
The 50-XXXXX is the etched PCB. DEC usually added a 1 to that number to
make it complete board.
Thanks, Paul

I have a few of the limited function and programmers
panels. I do not
recall either of them being dependent on particular backplane. I'll try to
pull a few a few later and check the part number on them.
Remember, a 54-XXXXX number can become a 70-XXXXX with the addition of a
cable or something simple.
