[time-nuts] Tbolt temperature sensor

[Mark Sims]

Thanks to a fellow list member I obtained a rev C2 DS1620 temperature sensor chip and replaced the rev E2 chip on my "flat line"  Thunderbolt board.   The board is now a "curvy line" board.  So the difference is definitely a DS1620 chip difference and not a tbolt firmware difference.

I made several 24 hour holdover runs with the old chip.  I am going to let the unit run for a week or so to let the filters learn the new chip and repeat the holdover runs.    Hopefully something will pop out of the data,  but I am not too hopeful.  There was not a lot of consistency in the data from the first holdover runs.   Any ideas of what to look for or how to analyze the data?
