Hi y'all!
Three utility programs were unable to correctly extract a file
from a DOS 3.3 format disk. An image of the disk in question can be
found at:
ftp://public.asimov.net/pub/apple_II/unsorted/modula21.sdk
The file I was trying to extract is "QLISTER.ABS". Extracting the
file with "COPY ][ PLUS 8.3" resulted in a file of the correct size
but all the high order bits were stripped off. "Apple II System
Utilities Version 3.1", running on a IIgs, and "CiderPress", running
on a Windoze machine, both extracted files that were missing the last
15 bytes of the source file.
The "Apple System Utilities" was really perverse in that it stripped
the high order bits of any bytes in the last 29 bytes of what it did
extract.
I finally got a good file by using CiderPress and manually
appending the missing 15 bytes shown by viewing the end of the source
file with "COPY ][ PLUS".
