RM-DOS
This was a multi-user MS-DOS lookalike for use on Sord M-343. It supported
up to 4 5.25" HD floppies (not compatible with MS-DOs) and a 10 meg
harddisk. It could read MS-DOS HD floppies.  The Sord could also run MS-DOS
2.11 with floppy HD support.

 How about variants of this, such as Diversi-DOS, and I'm sure others but
 offhand I can't remember their names. 
 
 Super DOS, Pronto-DOS, to name but a couple.  I'm sure there were maybe a
 half dozen more, though they were all just modifications of Apple's
 original DOS with speed enhancements.
 And if we're counting versions, Apple DOS 3.2 is somewhat distinct from
 DOS 3.3 (13 sectors per track in the former vs. 16 sectors per track in
 the latter).
 There was a very obscure DOS called RDOS that was featured on the game
 Rescue Raiders for the Apple.  If you boot trace the disk you can get
 access to it.  It uses it's own directory and file structure.  It was used
 on a few other titles published by Sir-Tech Software.
 Also, GS/OS (may have been mentioned already), ProDOS 16 (vs. ProDOS 8).
 For the PC:
 MS-DOS, PC-DOS, DR-DOS
 For Z-80:
 Along with CP/M, there was MP/M, ZCPR, and I think something called CP+(?)
 Someone already mentioned OASYS.
 Many others...
