48SX computer connectivity

[cruff]

The 48SX only has a serial port, which could be attached to a serial to USB cable. HP sold a cable that went from the 4 pins on the 48SX to a female 9 pin connector. People used to make their own from female pins epoxied to a piece of tongue depressor. I don't recall if I have my own version anymore, I have the official cable. If you go that route it would be easy to wire up a FTDI serial to USB adapter.

Then you can use Kermit to transfer data.
