[time-nuts] Symmetricom experts?

[G1FEF]

Do we have any Symmetricom experts on this list?

I've had a Symmetricom Syncserver S200 GPS+PPS with rubidium clock running for several years until we had a power cut and the UPS battery failed, on powering back up it won't boot at all.

I suspect the flash is corrupt but they protect it in some way, so one can't just copy the o/s onto a new card, and the company want ££££'s to fix it for me!

Thanks in advance,
Chris
