Kevin, Thanks for all the information re: the internal wiring.
It sounds like the 1 PPS output that was tested must be somewhere on the board, even if it isn't used. In looking at the test data, it appears that the boards were tested before final assembly. I am inferring this from the fact that the test data seems to bear different dates for the different assemblies.
I wonder whether there is anyone on the list with good connections to Symmetricom? It would be extremely helpful to get a service manual or equivalent information. As this is a discontinued unit, perhaps Symmetricom could be persuaded to release more information?
