HP-41 contrast control

[karl gruber]

Is there a way to control the contrast of the display?

Thanks,
Karl

Yes, as far as I know with the help of various moduls, like the HEPAX or the ML-Rom. Rom-images for both can be found on TOS, but you will need a device to load those images onto, like an MLDL, RamBox, Clonix,...

Hope that helps.

Cheers

And contrast control is only possible with the halfnut machines (the one with rounded display corners):
