     Well, DUH! Like it does seem to. (At least Nulib v3.24 does.) Thanks for
the info!

     Tried an experiment with DOS 3.3 and ProDOS ShrinkIt whole-disk 5.25" .sdk
files (both include compression).


Example: Go to the MS-DOS prompt (from Win95) and, in the DOS window, get to
the Nulib folder (where the .sdk files have been copied to simplify things).

   enter this--> nulib X copy2p55.sdk

   and the result is a disk image file.


     Both the DOS 3.3 and ProDOS .sdk files came out as perfectly good
143,360-byte disk images. Changed the file names to end with ".dsk" and they
booted fine under AppleWin.

     Me neither. Maybe there are some 5.25" whole-disk ShrinkIt files that
don't work-- seems like I may have run into one and decided Nulib couldn't
handle compressed .sdk's. Possibly, there is a problem with .sdk files created
by GS-ShrinkIt (usually, I use 8-bit ShrinkIt to create 5.25" .sdk files).

     In any case, a ProDOS .sdk file and two DOS 3.3 .sdk files tried all
turned out okay as disk images. Thanks, again, for clearing things up!
