Thank you! The HP-67 emulator maybe was a good throw.

As far as the font is concerned this is no problem, the classic LED font handles this with its regular period/comma. But I don't know if this a problem in terms of emulator programming. ;-)

When calculating the display string for the HP-67 emulator, the only thing to check is, whether the classic LED font is selected, if so a semicolon ; will be inserted instead of a period . , which shows the decimal dot at a higher position and occupies a full digit.

However if emulating the HP-67 or HP-19C on a HP-25 hardware with the new ACT, if a decimal dot is detected, it must be attached to the previous digit on the left. Two more digits must be eliminated by other means for displaying everything in only 12 available digits.

With the '67 I am using RGB 43,32,38 for this. Or do you know a way of displaying a TTF font on transparent background ?-)

I didn't yet try transparent font yet, but it is a good idea and is possible somehow. Perhaps I will make a (real final ?) version containing this feature Smile


That's one small step for a man - one giant leap for mankind.
