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, geo - n4ua _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
