It’s updated! I’ve finally fitted the 12 digit display into the HP21 emulator.

It has also had a bit of a tidy up internally and it has some of the new features from the other emulators. You can copy and paste from and to the X register, and you can see what is in the stack (and memory) at any time.

The product page is here. I think you’ll like the improvements.

It's only fair to share...
