== MoDOS ==
MoDOS was a replacement of Amsdos and included a new file system called "Prem". Prem formatted 40 track discs with a capacity of 212KB (instead of 178KB). Similiar to the FAT format it was able to handle sub directories inside an unlimited tree structure. The below image shows the Stream2 desktop, while both drive windows are open. (Left: Prem formated disk, Right: [[Amsdos]] formated disk). Files could be copied seamless between the two formats.
