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?

Love it!

I LOVE the way it reproduces the look as well as the action of the calculator. It just wouldn’t be the same without emulating the case, the ports everything. That is for this final but critical extra touch.
