Hello, all. The above referenced ca. 1980s MIDI sequencers (termed "Disk Composers" by Brother) all appear to use the same internal 3.5" FDD. The spindle is belt rather than direct driven. I can't find any specific belt info for these devices on line except for the FB-100 Brother drive which was intended for use with their line of knitting machines. I have the MDI-30 and I think a 8.5" or 9" circumference flat belt might work but if anyone can provide some additional detail it would be most welcome. Thanks for your time and comment. Sincerely,
