Here's another alternative:

I have a program which lets the Unix PC read/write to the "raw" disk
in 360K format, suitable for use with SCO Xenix "/dev/rfd048ds9" and
Regulus "/dev/raw/fibm" devices.  Probably others as well, but I have
tested those formats.

The usage is:

	fdwrite /dev/rfp020 <program_which_writes_to_stdout>
or:	fdread  /dev/rfp020 <program_which_reads_from_stdin>

For example:

	fdwrite /dev/rfp020 tar -cvf - foo bar baz

And then to read it on Xenix:

	tar -xvf /dev/rfd048ds9

It's just a ten-liner that ioctl's the floppy and then execs the
desired program.  I'll mail or post as interest indicates.
