Re: DOS 3.3 Image Does Not Work on XGS

["Bryan Parkoff" <BParkoff@satx.rr.com>]

Charlie,

    It is necessary to convert from binary to ASCII because NuLib will fail
to unshrink Image.  I have noticed that several bytes (>7 bit) are modified
while transferring from GS/OS to MS-DOS.  I do not understand why, but ASCII
remained (<7 bit) unchanged.
    I used Kegs32, but it failed to boot DOS 3.3.  I believe that DOS 3.3
has different sectors in order while ProDOS has sequence sectors in order.
Emulator attempts to read DOS 3.3 using seqence sectors in order before
machine language breaks and dumps register status.  Please advise.
