Well, not really a bug but just 2 minor cosmetic issues:

1) at start 'keyLabel' appears in the display (even if key labels are switched OFF), it disappears when the mouse is moved
2) the window title (appearing in the taskbar) is 'Form1', should certainly be something like 'HP-91 ...'

Though I saw neither when I initially ran this, I can confirm both as well on Win7 Pro. Good eye Franz.

Hi Franz,

Thanks for the info, I changed the initialization of these items, so hopefully fixed

New version uploaded.

cheers

Fixes confirmed. Amazing stuff Tony. Though it makes me want a real HP-91...

Getting better all the time, Tony!

Bugs found:
(1) CL Sigma doesn't clear regs .0 through .5 (which I think it's supposed to do).
(2) CLEAR doesn't seem to do anything.
(3) Shift 0 makes "Crd" appear in the display.
(4) Shift Subtract should subtract but seems to be a NOP.
(5) Shift PRINT x prints the stack in HP-97 style.

Hi Joe,

Thanks for the bug report.

It has proven harder than I thought to get this one running. :-)

New version uploaded.

Shift Sigma+ stopped working correctly. Instead of performing Sigma- as it should, it instead performs Sigma+. Oh, those pesky shifted funtions!

EDIT: Indeed, many shifted functions seem broken, e.g. 10^x, LOG, SIN^-1...

EDIT: 0 / --> Error... which cannot be cleared except by turning the 91 off and back on.

EDIT: RCL and STO no longer work.

It would be much easier to emulate the original HP-91 ROM code. If I could get an HP-91 from somebody (here in europe) I should be able to provide the ROM code.

Boy this model really got the better of me :-)

Sorry again.

Seems ok this time

Have uploaded again

Amen to that. If I get a copy then I can recreate the original.

Heavens to Murgatroyd, no need to apologize! Playing with this has been great fun! Anyway, isn't the process of finding inevitable bugs, tracking down their cause, eliminating them, thereby creating NEW bugs, and repeating the process, half the fun of programming?

Yes indeed. Appears to be quite solid. The bugs are on the run. Good job, Tony!

Too true, too true, but they seem to have changed my hair colour of late :-)

Thanks again for the feedback
