$>Not entirely kosher, but it will work.  If you can locate a copy of the

$
$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.

PLEASE PLEASE POST THIS.

It would be most helpful to us and many others who are trying to interchange
with a 3b1 and having no end of trouble.

Also -- is this code freely redistributable?

Thanks!
