HP-41 Contrast - larthurl - 12-24-2017 12:47 PM
I seem to recall that there is a way to adjust the display contrast on an HP-41. I don't remember how to do it and can't find it in the manuals I have.
Anyone know how?
Thanks

You need a HEPAX module or MCODE.
Here a description. Sorry German:

At the bottom of the German article you find a link back to the old forum on this website

It is described in the book "HP-41 MCODE for beginners" page 115-116, only works on Halfnuts.
