Time-nuts;

I have three, essentially new Trimble Thunderbolt OEM boards for sale. These
were part of a production lot that had been returned to Trimble (several
years ago) from the OEM because the wrong zener had been installed in the
voltage sense circuit. This is the zener that allows the unit to work from
-7 Vdc (instead of the Trimble-standard -12 Vdc) without the Power Supply
alarm being invoked. Trimble changed the diodes, and the units were returned
to the OEM; these three were never installed in production units. In fact,
they are still sealed in the anti-stat bags that Trimble shipped them in.
This is the connectorized board that is normally mounted inside the
gold-colored aluminum case that everyone is familiar with.

The units have version 2.2 firmware, and all have the older D1 date code
DS1620 thermometer chip with the smaller temperature steps. $150 each for
the board assembly in the sealed bag; for another $10, I will install the
board in a case and throw in a power connector. Or, I can supply the case
and you can install the board. All, plus $5 each for flat-rate shipping.

73,
