Conn4x with HP49G+



#2

I got my new revision 1.20 calculator the other day, installed the software and USB driver on my Windows XP Compaq (USB 2.0), and connected the calculator. When I fired up the software, the ROM menu option is greyed out. Any ideas on how I can upgrade the ROM (without an SD card)?

Thanks.

Look around at http://groups.google.com/groups?q=comp.sys.hp48. The answer's probably there, and fairly recent.

Hello,

the ROM option will become available if you select the dedicated USB com port (something like "HP-4xG+"). Then, you can upgrade your calc. Make sure to select 115kbps (kind of slow otherwise).

Thank you both. Yes, I am Alan Smitthee, famed movie director of most of the flicks on USA Netwrk in the 70s and 80s.
