Could you provide some more information about RPL and tell me how do I flash it on my 39gs?

1) I use HP Calculator Connectivity Kit (CONNX3) on WinXP under VirtualBox. 2) Check USB port forwarding in VirtualBox https://www.eltima.com/article/virtualbox-usb-passthrough/ 3) Use standard instructions from "Mastering the hp 39gs & hp 40gs", section "Flash ROM"
