HP 50G - ROM upgrade under Linux


Hi all -

Has anyone upgraded the ROM on a 50G under Linux? I maintain a Windows-free computing environment at my house, and as I am looking forward to tackling a multivariable calculus course in the fall, I'm using the 50G a lot more. I'd like to know if there is a way to do this.

At worst, I guess I could try running the Win connectivity software under Wine, but I'd prefer a native solution.




Just download the HP-50g ROM update file to an SD card and follow the instructions at Educalc.net:

IMHO, Windows or non-Windows, the SD card update is preferable.


I've found VirtualBox to be a great solution for running Windows XP software under Linux. I've used QEMU and Wine extensively, and believe VirtualBox to be the better of them - especially with TI calculator software.

...Wine extensively...

Christoph Giesselink's emulators (http://hp.giesselink.com/emu48.htm) work well with WINE. So if x49gp is too much hassle, then emu48 (the debug4x build) works great with WINE.

You do not need Windows at all to enjoy the 50g. The 50g without Windows:

  1. Can flash with SD card.

  2. Can be truly emulated (i.e. true ARM 50g emulation). http://x49gp.svn.sourceforge.net/viewvc/x49gp/README.QUICKSTART. Screen shot here: http://sense.net/~egan/hpgcc3/pics/x49gp-osx.png. NOTE: Please do not ask me to port to Windows.

  3. With DOSBox/DOSEMU you can emulate a printer and print to it: http://sense.net/~egan/virtual82240b/. More information here: http://groups.google.com/group/comp.sys.hp48/tree/browse_frm/thread/c694a8c429f4c623/8204b04a11a19d27?rnum=1&_done=%2Fgroup%2Fcomp.sys.hp48%2Fbrowse_frm%2Fthread%2Fc694a8c429f4c623%3F#doc_8204b04a11a19d27, Or natively in Unix/Linux: http://www.hpcalc.org/details.php?id=7081

  4. Write HPGCC2 programs (http://sense.net/~egan/hpgcc/) or HPGCC3 programs (http://hpgcc3.org/).
You do not need Windows to get the most out of your 50g. I cannot think of a single thing that you'd ever need Windows for. However, if it comes to that, VirtualBox (mentioned above) is a great solution for the emulation of legacy operating systems. :-)


Many thanks to all who replied -- I look forward to exploring some of these options. %^D
