Increasing the resolution of the screen on the HP28 or HP48. Possible ? - Alejandro Paz(Germany) - 11-23-2017 09:00 AM
Have someone tried any inroads into increasing the resolution of any of these machines ? Any ideas if the amount of code to change is that large and/or that complicated, I mean there are 128..256 kBytes of mixed code, enough for a lifetime of searching, I think

I think the most cost-effective (and time-effective) answer would be to simply get a 50g. Same RPL, higher-res LCD.

I'm not talking about the real HW, my target would be say EMU48 or my own re-implementation of the Saturn chipset with a bigger display: I ask specifically about the SW running on the Machine. When the target is EMU48 (or any other emulator) it is a matter of using a bigger bitmap to display on the PC screen. Sorry for the possible confusion.

Hello,
Unfortunately, most of the 28/48 SW is unable to cope with a different resoltution screen.
Prety much all the UI code is very, very resolution dependent.
The 50G series is a little bit more tolerant of height resolution change and might mostly work with a higher screen, but this is as far as you can go.

That, I feared.
Thanks for the answer.
