Without USB, you can do this with an SD card, an HP 48 serial cable, and one of my HP 50g serial cables (not presently available but I'll make a new batch soon).

Use the SD card to load the 48 software from the PC (strange would you have a computer with an SD card reader but no USB port) onto the 50g. Then transmit via serial from the 50g to the 48G. If it's a binary file, you'll have to use some variation on OBJFIX to fix the header for the 48G, and if it's an ASCII file (User RPL source code) you'll need to do the character translation.

Hi Eric - No I didn't mean I have no computers with USB right now! (Maybe 10 years from now that would be the case?!) But what I have is a MacBook and usually sync software, especially legacy software, wouldn't work on Mac OS X. I do not have Windows at the moment, and I can't run Windows either on my Mac because I stopped paying Parallels (the virtual machine for installing non-Apple x86 OS) every time to "upgrade" whenever I upgrade my OS.

(My old Macs in storage are on PowerPC and would run classic MacOS 9.x so probably they can use the original HP 48G software for Macintosh.)
