I now have 35 HP related calculators on my PC...

Much appreciated, Franz.
The algebraic calculators are hard to find.
My trusty HP-27S, that I have has since 1988, is sitting on my desk.
I use it daily, & am battling to find a 27S emulator for android, freeware if at all possible)

Regards,
Robin

After 3 hours, 10 minutes, the Emulator download is at 937 MB downloaded.
So far, so good!
