I have the complete manuals (Programming, Technical, user etc) for the HX20. If you let me know what you need, I can let you have the information you need.

Have you tried doing the CTRL-_at_ reset trick? HX20s have a habit of getting corrupt memory ;) The battery might be getting a little old, too (and don't run off AC power without a good battery, as it acts to limit the raw DC input voltages seen by the machine)

On a related note, I was wondering if anyone had any ideas about how to transfer HX20 disks to PC. The TF-20 wrote 320K 5.25" DSDD disks. I have two 5.25" (Epson brand) floppy drives in a TF20, but I'm not quite sure about how to hook them to a PC floppy interface (or if it is even possible). Each drive has 4 dip switches (presumably for A/B settings etc), but no settings documentation. The other way is to use the TF20 via the serial port, and pretend to be an HX20.
