First calculator with gamma function ? HP or otherwise ?

[Gene]

Hello Dominique and welcome!

I am glad you have joined us here. I have loved your website and overviews of calculators, HP or otherwise, for some time.

Couple of questions:

1) Your calculators tend to show the same number in the display. Where does that number come from ?

2) If you get a chance, some of us would **love** links to high quality pictures of your machines.

Glad to have you here! Your English is fine. Try to imagine my FRENCH. :-)
