Yes, pkzip and gzip are two completely different compression programs.
"zip/unzip" are the Unix version of pkzip.

I'm not sure that unzip (unix) can do disk spanning.  If you find
that it cannot, you could try coping each file on the diskettes to 
your hard drive, and combine them all with "cat".  Then try to unzip
the combined file.  I've never tried this, but it's worth a shot.

i.e
for every diskette:
	mount /dev/fd0 /mnt/fd0
	cp /mnt/fd0/* .
	umount /mnt/fd0

Then you should have a bunch of files like:
	zipfile.001
	zipfile.002
	zipfile.003
	.
	.

Then you can "cat zipfile.* > combined.zip" to combine them all.
Then try a "unzip combined.zip".

Good luck, and let me know how you make out.
