I’ll edit this if I find something more but a quick scan for the manufacturer part bring up 3 types of drives. 5.25 inch disks, all aftermarket. Some branded Chinon, others from dozens of third party manufacturers. Including an Apple Disk II clone, and a commodore compatible.
OEM tape drive controllers,
A 3.5 inch controller for aftermarket PS/2, PC Jr, and PS/1 drives. Allowing the multiple formats of different systems to be able to be accurately read in a single “super drive”. Different disks at the time had different track layouts from different vendors for different manufacturers. I remember the idea of super drives but don’t recall ever having one. Oh, fwiw, all current (usb) external floppy drives can read most of the disk types.
