Several people (Becky Stern, Steve Conklin and others) have, over the years, developed a Brother disk emulator and python scripts in order to be able to load patterns in to the Brother 930 knitting machine.
The Brother 930 is a USA-only model. I am in the UK, and the nearest equivalent is the Brother 950i. I also wanted to add an 'Aunt Marion'-friendly front-end that would also speed up the process for use demonstrating at Maker Faire.
