HP 49g - Stuck in No System menu
So, I found my 49g a few weeks ago and put new batteries in it and it promptly brought me to the no system menu. I have tried most of the documented reset button combinations with no success. I found my last computer in the house with a serial port and was hoping to connect and upload the flash is onto the calculator, but the connection software wasn't able to connect. Tried HP Comm as well as a simpler comm program from this site.
I know there isn't a lot of love for the 49g, but I was wondering if anyone had any suggestions? |

I had to patch hp49flash to force it to talk to /dev/ttyUSB1 (@ https://github.com/gwenhael-le-moine/hp49flash I don't understand why this glorified shell script was written in C) At some point doing this I did end up in a state maybe similar to yours where I had no OS installed.
