I've got it in the wrong way round several times
and it's never done any
damage. It just doesn't work (no display at all IIRC).
Berg cables in DEC machines are rarely keyed, alas.
Actually, I can point to a number of counter-examples of that...
Anyway, I'm simply going to keep the cables in the machine in case
I want to do it at a later time... I have so many other things to do
with the machine to get it running first...
I've found the VT11 prints - sort of. I've got
the schematics of the 3
boards :
M7013 Display Control
A320 Display Generator
M7104 Bus control + bootstrap
They might be useful at some point... but not yet (I haven't even found
my VT11 boardset, if I have one).
What I don't have is any information on the
backplane. So I don't think
I'll be of much use at the moment.
Again, problem is moot until I have more of the required pieces... I'll
keep you in mind for the other info though at some point...
I know I don't have the LPS printset. I do have a
minimally-configured
LPS somewhere, though.
I haven't opened mine up yet to see what I have... if you can easily
get to yours, it might help to have info on board order, and UNIBUS
connection point... (I take it a terminator has to be in the LPS
since it connects to the UNIBUS itself...)
BTW - It was pointed out to me that the file containing the picture
of my haul was somehow protected... I've taken care of it.
Look for a trip writeup with pictures in the near future (I've got it
mostly written, I just have to insert the thumbnails and links to the
full pictures)...
