Some assorted HP67/97 questions

Since the current bitmap is 200x400, this would mean a height of 600...800 pixels. So we seem to agree here. ;-)

Looks like 2:1. But a new image file with the same aspect ratio does not neccessarily mean that the keys are also placed at exactly the same relative position as in the original smaller file. And there also may be an issue with the display which does not seem to get enlarged.

What about placing an HP67 on a usual flatbed scanner, scan it at 300 dpi (which is several times what's required) and finally reduce the image dimensions to your display resolution? This way the size matches the real device. However, I'd prefer it somewhat bigger. 350x700 or 400x800 pixels are fine by me.

For entering a new program via file input, does the source file have to have the exact number of lines (99 I assume) or could it have more or less lines and load without problem?

GTO . 000 and press h BST. You see the last step in memory, that's step 224.

BTW I had a few problems: SST does not seem to display the next step when held down, and in some cases SST made the program run (as if R/S had been pressed). In another case I could not stop a running program – exiting the emulator was the only solution.
