Full Version: HP 50G - ROM upgrade under Linux
You're currently viewing a stripped down version of our content. View the full version with proper formatting.

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:





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.

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

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. :-)

...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.

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