There were double sided and single sided "flippy" drives
Amdek made add-on external 3" floppy drive units for Apple][ and Coco.
The "Coco" one was, of course usable with almost anything that used an
SA400 interface at a 250K data transfer rate. You would probably need
back issues of 80 Micro, Rainbow, or Computer Shopper to be able to find
the ads for them.
A handful of 3" drives could be turned on edge to cram into a 5150 drive
bay
