[time-nuts] Help identifying a display board

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.
