It could be a combined time display with a channel number and
measured value, from some kind of data logging instrument. L&N was
big in thermocouple measurements and the like. With those digits you
could show temperature at three digits resolution, selected channel
00-99, and hours and minutes, with the LED for AM/PM.
One clue would be to see if they used any of the Panaplex decimal
points. None would be needed on time or channel readouts. If only the
second DP of the three-digit one is connected, then it could be set
to 1 or 0.1 degree resolution. If no DPs at all are used, then the
temperature could show 1 degree resolution, and display -99 to 999
deg F or C, which is a pretty decent range for common T/Cs, depending
on the application. It could even work for cryogenics, reading say
000-999 deg K.
The board also appears to be missing one DM8880.
