Conn4x with HP49G+


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)?



Look around at The answer's probably there, and fairly recent.



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.
