I would agree. It smells as though it is part of a SCADA/control

but I have only seem a small amount of Honeywell control gear - so
could be completely wrong.
It could also be from a Harris machine.
I have no idea when Honeywell or Harris started producing control
systems so the dates may invalidate everything I have typed so far.
I bought two front panels from some type of
computer from ebay for the
switches and lights. After receiving them, I find they are too neat to
tear apart. They were said to come from a telephone company central
office. Does anyone recognize these? I can't find any names on them.
I'm sure that someone will recognize this, but I don't think it's a
from a telco CO. This looks more like a triple-redundant setup for
some sort of mission-critical application (nuclear reactor control?).
The indicator lamps labeled "SURVIVOR" and "BACKUP" as well as
"EXCHANGE FILL" would seem to bear this out as well as the alarm
resets. Incandescent lamps instead of LEDs would probably put
this in the
1960s-early 70s, maybe?
This was my initial assessment based on the way the wiring looms are
tied. Since, the eagle eyed Jim has pointed out the inspetion date of
68.
My 2c worth.
