[time-nuts] Datum 9390 - Y2K update?

[Karl F Strauss]

I just purchased a Datum 9390 off EBay.  The seller is warning me that she was told that the 9390's need some sort of update w/r/t Y2K in order for it to operate.  The seller states (and the pticures show) that the unit responds Self Test OK during power on.

The seller is giving me the right to bow out of the sale if the unit cannot work.  My main goal here is to develop a precise 1PPS and millisecond tick.  To be able to pre-set the time and date would be ideal but not ABSOLUTELY required.

Advice, please!
