[time-nuts] Looking for info on Trimble 16634-10

[Scott Armstrong]

Hi Guys,

I popped open the case.  Not too crowded in side. The case is an extruded
aluminum case that has the back endplate  welded on.

There are 4 board assemblies in the case.

*Interface board that connects the 22 pin connector to the other two boards.
* Power supply board. (12016-00). Main component looks to be a DC-DC
converter made by Computer Products.
* Main board (14636-)  This board has a 16.368 MHz osc made by NDK.
* A daughter board (14789E) which is the receiver and is attached to the
main board.

Date codes I see are 89, 91, 92 and 93  so unit was probably assembled in
'93.

Maybe some of the assembly numbers will be recognizable if they are used in
other units.

Thanks,
Scott AA5AM
