     Don't know. Sounds like a pretty good process.

     Some possible problems are ...

o- When you made your images on the PC, you used one or two .dsk images
which were in ProDOS order. These are rare; but, there are some. (ProDOS
order disk images are usually .po files.)

As far as I know, ADT does not try to check the sector ordering of
a .dsk image. So, a ProDOS ordered image with a name ending in ".dsk"
might well be sent and end up mixed around when written in DOS 3.3
order on the target diskette.

o- There are several .nib images in the M&M II set. I'm pretty sure that
Only the first image (Disk A) is bootable. If you sent one of the other
images, it probably would not boot.

o- M&M II requires an enhanced //e (or later model) Apple II. If your //e
does not have 128k or if it can not display double-hires, the boot disk
may hang during booting.
