Want to duplicate my software source floppies

[Thad P Floryan]

The question has arisen about duplicating one's Foundation Set in particular,
and duplicating random floppies in general.

Any "good" double-sided, double-density 5-1/4" floppy is acceptable to the
system, but I'd recommend NOT getting the bargain-basement "white box" floppies
unless you like to convert your floppies to diving mask face plates ... i.e.
the oxide rubs off onto the heads in the floppy drive and you end up with a
transparent "sunglass" lens for your diving mask!  :-)

To determine the PRESENT formatting of an "unknown" floppy on the UNIXPC:

	$ iv -t /dev/rfp020

A general-purpose floppy copy shell script I use that has been distributed at
our Users' Group is enclosed.  Strip out everything above the "cut" line and
run thru /bin/sh per the instructions.
