Re: HP-41 contrast control Message #2 Posted by PeterP on 16 Jan 2006, 3:32 p.m., in response to message #1 by karl gruber 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 Peter
