Odd DEC panel available.

[Bob Shannon]

This turned up while I was collecting some indicators for a control panel 
project.

But this might be something that should not get chopped up, and I'm not 
quite sure
what this is (was).

Its a 19 inch wide, rack mount panel with a 36-bit indicator register using
Dialco 507-3917 incandescent lamps (5 are missing).  There are also 4 toggle
switches (one dammaged).

The panel itself is .250" thick plate, painted grey with hand-written labels 
written
on masking tape.

Behind the panel there are two (DEC) 4918 18-bit Indicator boards with 
transistor
drivers and connectors for logic and power.  Spade lugs supply the power 
while
a single-finger 'unibus-like' female edge connector is used for the logic 
signals.

The toggle switches are connected by multi-couductor flat cable (not modern
ribbon cable) to a 3-66 PERFORATED BOARD W994A, which is a single
finger 'unibus-like' male edge card connector.

It gets more interesting when I read the handwritten labels above the 
indicators.

I'm guessing this was part of some PDP-10 to PDP-6 interface kludge made
from DEC logic modules.   Is this part of some well-known kludge, it 
probably
came from MIT's surplus equipment exchange back in the mid 1980's, but
its clearly much older than that.

Is this something someone wants, or should it be canabilized?

( I gotta Google on a PDP-6, I dunno that one, but I know what a -10 is!)
