Ah, those were the days! :-)
 
I got tired of playing around with Muffin, so I added a patch
to Apple DOS 3.3 which allowed it to read and write both 16-sector and
13-sector disks -- and auto-adjust itself on the fly!  It wasn't that
hard.  Later I added 80-track double-sided floppies, and got them to
work on Apple DOS and on Apple CP/M.  On Apple DOS I put one disk
volume on each side, and called the "other" sides of the floppies
"disk 3 and 4" (I had two such floppy drives): one DOS volume then
became 320K large.  On CP/M I let one volume span both sides of
the floppy, and thus I got 640K CP/M disks instead of 140K -- that
made a pretty big difference.  The flip side is that I'm probably the
only one in the world who runs that particular disk format (no, not
the only one -- I know a friend who shared my code...).
 
Of course I have a copy of Apple-Trek around somewhere.  I even
compiled it with "Flash! The Integer Basic Compiler", and as a
binary file it could be run even if you lacked Integer Basic in
ROM or in the Language Card (I used to throw out Integer Basic
and put the S-C Assembler there instead).
