[time-nuts] Another Trimble Thunderbolt-like GPS?

I agree with Peter. This board has been sawn off the end of a larger PCB. The PSU is typical telco, 36-75V.
Half the price of a standard Thunderbolt though.

Most of the parts (and their grouping) seem the same as the NTPX26AB -
which based on my quick play with one seems to have basically the same
hardware as a Thunderbolt.  The only strange thing I noticed was that
although it would work with the Trimble tbolt software Lady Heather
couldn't recognize it.

Maybe I'm being paranoid, but looking at that photo it looks like part
of the board has been cut off - this would also explain the slightly
evasive "I'll tell you where the power goes after you buy it".  Of
course, this won't necessarily stop it from working, but it might be
worth checking.

Regards,

Pete
