I can't imagine a reason anybody should want to know anything about my person. So i put it here away to make sure it will get in nobody's way.
I'm born on 22. July 1962, married, with one child (born 1991). I've studied computer science from 1981 to 1987, being occupied as a software engineer since then.
My interest in pocket calculators is almost as old as pocket calculators are, starting in about 1976 with the HP25. My most active period was at the end of the seventies/beginning of the eigthies with the Ti-58/59. Since 1988 i'm collecting calculators.
