I see blue consoles from a PDP-15 and a DECsystem-10 (KI-10).

As for the two panels Noel asked about, I've had a look at the chassis which
are part of our DEC-1070, and have eliminated the following possibilities:

Only 3 rows of lights:
ME10 memory
MF10 memory
TD10 DECtape controller

5 rows of lights:
KI-10 CPU bays
RH10 Massbus interface
DAS33 memory buffer

4 rows of lights, but do not match:
RP10C disk controller

Since they're narrow, they're probably something from a KA-10 system, but I
have no idea what.
