I am cleaning out a box of old gear here and ran across an interesting doo-dad... a Vaisala "MPT 11" - what seems to be a "manual papertape reader" - smallish PCB with a U-shaped plastic tape guide for what I think is reading in the calibration papertapes for Vaisala sondes (when launching a balloon, certain models of sonde have a papertape in each one that gets fed into the telemetry box prior to launching). I googled for a few references, but only turned up part numbers, no technical docs. Not really surprising for embedded stuff from 1999. There are other things in the crate - what look to be single-Euroconnector-attached boards with embedded GPS receivers, etc. (also from 1999). One CPU board looks to have an 8031 at 7.mumble MHz, and there's a DC-to-DC converter or two on the same sized boards. Probably from a rack-mounted telemetry box they used to have around here. I also have small box of the GPS units from the sondes themselves - helical copper wire antenna sticking out of an RF shielded board. There's a 3 or 4 wire interface, two leads of which go to an 8-pin SMT 78L05, so power should be easy to trace, the remaining lead or two is going to be some format of serial data, probably TTL, the only question is what format the data are in. If anyone has or knows of a Vaisala technical docs repository, I'd love to hear about it. Thanks, -ethan
