Nice vintage calculator collection Claus! I finally paid a mind to your '70's computing' link in your signature area and decided to take a look. The clicked the link here to the Datamath Calculator Museum to look up my TI-2500B Datamath. It's in excellent condition and has been sitting next to my Atari 800 for years, to use with the 800 when I'm doing my financials with 'Your Personal Net Worth' and Syncalc and other Syn series apps.

 

The picture posted I lifted from the museum as it was easier than taking a picture of mine at the moment.
