[time-nuts] TruePosition GPS Receiver firmware

Cool. Should be interesting to see what you find. I've been hacking at the VxWorks side of things, off an on,
but have been distracted by this #wannacry business among other things. That TL866 is certainly a good value,
and it seems to work well. 

Looking forward to hearing what you turn up. I'll keep poking at VxWorks in the mean time.
