   Good start.   :)

   The c.s.a2 FAQ details several Apple II programs that can unpack
.SHK files on the Apple II side. Those programs do a good job of
getting the filetypes right, and might have been the easier solution.

    Nitpick: that should probably be 800K if it's read on a normal
Apple //c.  PCs are inefficient in their disk writing mechanisms. :)

   With BLOAD and BSAVE, and non-'BIN' filetypes, you must specify the
alternate type. For example, to change a filetype from $00 to SYS, try
the following:

BLOAD FUBAR,T$00,A$1000,Lxxx
CREATE BARFU,TSYS
BSAVE BARFU,TSYS,A$1000,Lxxx

   Where 'xxx' is the file length of the file. If you didn't force
binary mode in downloading, the filesize will pribably be different
from what nulib showed. [By the way, the c.s.a2 FAQ has a section on
changing ProDOS filetypes with a program (that you'd have to
download), as well as changing it manuall like above in the
downloading Todd Whitesel's BINSCII.TXT section.]
