First calculator with gamma function ? HP or otherwise ?
Detective work time... what was the first pocket calculator produced that would commute gamma? Not a program keyed in, but as a built in function?

I have found one from sometime in 1975 (!)...and yes the (!) is a pun on factorial/gamma.

Anyone, I'll post what that model is shortly, but what can you find? HP's first? Some other model near or earlier than 1975?

Enjoy the search.
