This was quick: about half an hour.
And that at Christmas.
I can confirm that the bug is fixed.

I can only recommend Eric Smith's nonpareil emulator:

Quote:In this release, the following calculators are simulated:

    Classic series:    35, 45, 55, 80
    Woodstock series:  21, 22, 25, 27
    Spice series:      31E, 33C, 34C, 37E, 38E, 38C
    Nut series:        41CV, 41CX
    Voyager series:    11C, 12C, 15C, 16C

    Modified Voyager:  15X

Since you're writing your emulator in Rust, I'm assuming you're also familiar with C.
So the documentation is in the source code.
But my understanding is that all of these processors have gradually evolved from the original processor used in the HP-35.
So if you know that one, you kind of know them all.
