OT: functional picture of an ARISTO M27 Message #1 Posted by Mike (Stgt) on 19 June 2012, 7:26 a.m. It is not an HP, it is not UPN, it just looks like the first german pocket calculator. And it works. Click here and get a ZIP with an abstract in Enlish, a description in German, and an EXE that should do on Windouze PCs. Ciao.....Mike

It is perhaps less known that they also offered calculators (21 models, 1972-78). From 4-bangers to advanced scientific/statistic with hyperbolic functions. Very well made and sturdy. I own two scientific specimens, still operating perfectly. Only disadvantage: they are algebraic :-(
