If I remember correctly, the last time I looked on my 6386E WGS in the
office, I vaguely remember a program called /etc/.cpiopc  ... Looking
at the string table for that (with strings /etc/.cpiopc) I noticed some
strikingly familiar strings.   Things like:

To Exit - press <E> followed by <RETURN>.
To continue - insert floppy disk #%d and press the <RETURN> key.
...

Just to be sure, I looked at /bin/cpio on that machine and it didn't
have the same stuff.  So you might want to try that to read floppies
that were written with the -B option on the 3B1.   Note that /etc/.cpiopc
doesn't have the options like:

Usage: cpio -o[acvBT#O#] <name-list >collection
		   ^^^^
For buffering and offset location when using the tape device, not to
mention that you can't use it with the floppy drive as well...
It would be strange (as well as insane) to have multiple savesets on 
one floppy :-)

One aside... that cpio has the options in the usage for T and O, although
the Tape documentation recommends using tapecpio (which has those options
too, but they aren't listed in the usage).  /bin/cpio works just fine with
tapes as well...  I presumed

Thanks Pete for the information on transfering files from the 386 to
the 3B1...
