    Does this allow use of ROMs available on the net such as the Advantage Pac?

      [XEQ] [ALPHA]
      Then enter the correct sequence of characters of the operation, e.g. "FS?C" using the blue key legends
      [ALPHA]
      Now the calculator will prompt you to input the Flag number.

    Hi,
    I really *love* this great piece of software, enabling me -- an older electrical engineer -- to still use the favorite calculator of my students days!
    However, I wonder if there is any change to also add the great MATH module I had for my real HP41C in those days.
    Maybe you can advise.
    As I still have the working original HP41C + module "MATH I"; if you need any further info I can assist with, please let me know.
    Many thanks,
    Dirk

    Have used the great V41 for years - ending use now because on Windows 10, the emulator does not save the setting of the font. I turn off TrueType font because digits extend beyond right edge of display. When I re-invoke V41, it is back to using TrueType fonts again. I have been unable to fix this problem.

      I'm using V41R8 and install it in my user directory (C:\Users\marti\Progr\HP41R8) and it works in Win 10 (Options --> More Settings --> TTF off --> and it's still off)

        I find the same problem - turning off true type doesn't persist. I did find that if you toggle the size button in settings from large to medium and back to large, the display is corrected. A little annoying to have to do this, but it does work. (Reply)

    Dear Gentlemen.
    I am an engineer graduated in the last century and I do not like and I do not know how to use another calculator other than the HP 51X series. So I would like to express my sincere thanks for allowing me to download the emulator program from my inseparable HP51CX. Thank you very much.
    Best regards.

    My kid somehow made my HP-41CX display in British mode (I guess). It uses a comma where in the U.S. we'd use a decimal point. How do I change this back to US format? It's driving me nuts. I'm a homeschool Mom and I use this calculator a lot.
