I have a PowerBook 150 running 7.mumble. I want to be able to read/write/format 400kB MFS disks so that I can test MFS support on another platform. Does anyone know of any extensions that add full MFS support, including being able to format them? (Depending on the MacOS version I _may_ have read-only support, but as I don't have any MFS disks to play with I can't test that.)
