DOS 3.3 does use the high bit (bit 7) in ASCII text files where the PC and for
that matter ProDOS do not.  But as I understand it you are trying to boot a DOS
3.3 image (on an Apple IIgs emulator) of a DOS 3.3 disk that works on a real
Apple IIgs.  At no time should you be changing the high bit. or anything else
in the file other than the shrinking/unshrinking done by ShrinkIt.

Ok!

Well, if that's where the process breaks down then either MUG 1.0.1 or the
BlueDisk controller is changing the file.  I don't believe either should be
doing anything to a file but I am not familiar with how the BlueDisk or MUG
1.0.1 work.

Sorry, but I don't know anything about UUENCODE.

The only thing I can tell you is how I do it.


1.  Use ShrinkIt on my Apple IIgs to create the DOS.SDK file.
2.  Format a 720K MS-DOS disk on my PC.
3.  Boot the PC Transformer and then put the MS-DOS disk in my 3.5"(800k)Apple
drive.
4.  Use the Transfer program to copy the DOS.SDK to the MS-DOS disk. I do not
select the translate option as I believe this would ruin the DOS.SDK file.
5.  I put the MS-DOS disk in my PC and import the DOS.SDK file into a 32Mb 2mg
image that I use as a hard drive for Kegs32r3. I use FishWings to do the
importing.  The only thing to remember here is that you have to set the file
type to LBR or $E0 and the auxtype to 8002.  I then run Kegs and use ShrinkIt
GS to unshrink the DOS.SDK back to a disk image.
