I was in Munich last week and visited the Deutches Museum, which is all about science and technology. A wonderful museum, highly recommended to anyone here.
In the aerospace section I found this small exhibit about a German astronaut using the HP-41CX on the SpaceLab D1 mission in 1985. The English text reads:
D1-SAPCELAB [sic] Mission, 1985
Calculator: Hewlett-Packard, USA, 1984
Voltmeter: Walcher Elektronik GmbH, Kirchheim, 1985
The voltmeter is an instrument for measuring voltage and temperature. It contains an analog-to-digital converter that feeds the measured values to the calculator for processing. The calculator is a slightly modified standard HP 41 calculator. Astronaut Ernst Messerschmid devised this voltmeter to be used for experiments in materials science aboard the 1985 German D1 mission.
The exhibit includes the calculator and the voltmeter, with an interface to one of the expansion slots. There are two notebooks with the handwritten program code, derivation and userís guide. A couple of lines of code are obscured but it would be relatively easy to replicate.
Jimmy, you are welcome to use these photos on your site. The photos are quite large so I am including just the links below for download.
