This is one of the mystery devices. From information gathered so far,
it appears to be the maintenance panel from a Microprogrammed
Peripheral Controller (MPC) from an early 70s Honeywell 6000 series
mainframe. The only picture I've found so far is
this.
The maintenance panel would have been under the red cover, with the
illuminated pushbuttons sticking out through the cover. More pictures
may be found
here.
I also found that a panel very similar to this was used as a
prop
in Irwin Allen's
Voyage to the Bottom of the Sea.
