Latest Update Caused Problems - Now Fixed!

UPDATE - The display issue from v7.6.1 is fixed - via 7.6.2. The calc is now back to the great tool that it has been for quite a while and I look forward to continuing to use it for another few years. Thanks. PRIOR - The most recent update may have made for compatibility with the latest iOS (I haven't tried it yet on my Android and likely won't based on this experience) but it no longer works on my Mobile that has an older iOS. The background graphics no longer scale up to the screen size so the touch points for the calc do not agree with the visual indications for the buttons. Avoid this version. Wait until it is fixed if you have an Mobile with an older iOS.

Mazel Tov!

I wore out my HP-41 calculator but it was the thing that brought me back to programming after a nauseating experience with FORTRAN 77 in 1981. I wrote nearly 200 programs on that calculator. It got me through engineering school, taking the PE, working on the Hubble, B2, and 7x7s. I’m glad to have it back, even just as a calculator. I’m curious: Can I still write a subroutine to cause the calculator to automatically shut down when I turn it on using flag 11?

The REAL thing...

Latest speed enhancement is phenomenal! Thank you. Now if we can have it always “ON” when it comes up, then it would be perfect! Is there a setting that would have turn on automatically when it starts?

The Best RPN Calculator.

For all the reasons HP RPN scientific calculators are used for engineering, this calculator is simply the best. All the features of the best HP calculators, with improvements. Outstanding.
