Luck of the draw that time Smile

It was a strange bug. It would only appear when a HP code line executed under a certain condition, otherwise things ran fine.

These bugs are very hard to find so to try and work with them, awhile back I created a small monitor program. This can capture every HP instruction that the PIC executes, plus program counter and register values and then I can compare the output to the PC emulator.

After narrowing down the problem, I checked the source for the PC emulator and it had a small piece of code that the PIC didn't have. Once put in, all was ok.

cheers

Hi Tony,

I hope this is an easier bug:
The menu items on the HP97 are mixed up. "tr" is program mode, "NN" is run, not sure about the rest, as I am currently not connected to the PC and can't print.

Cheers,
Harald
