Nah... It's a standard DL11-W or DL11-E in there... However
it's not uncommon for LA120's to get their baud rates reprogrammed
to be used off a PC when the PDP11's being decommissioned.

I'd try to deposit a 301 (octal) or was that 101 in the
output register to the console output buffer -- (was that 777566) -- I
don't have any docs here. Then I'd see if there's an "A" on the LA120...
Try that with all the different LA120 baud rates until it matched.
