I'm relatively new to the list. I've been working on figuring out the protocols and file formats for the Brother KH-930E.
I've written a program in Python which emulates the external floppy disk. It's not really designed for easy use, and I only run it under Linux, and don't plan to ever use it on windows. Nevertheless, I hope
that others find it useful.
I'm using it to figure out the file format for that machine. I've been making progress, having started with information from this group's file section, but don't have anything well documented to report yet.
For more information and a link to the disk drive emulator, you can Visit here.
I hope this is helpful to someone else!
