[time-nuts] Trimble Tbolt temperature

[Arthur Dent]

If you choose to replace the DS1620 keep in mind that there are different
revisions of the chip and the 'E' revision displays the temperature in
larger steps than the previous revisions but the 'D' version is still
pretty common and it probably doesn't make any difference other than how
the Lady Heather graph will look. I'm not sure how the newer revision chips
work. The DS1620 chips are fairly cheap on eBay and several sellers have
them.

Check the discussion on the chips from 2010 that describes how to check the
revision.
