    I just got a DN3000 beast with a floppy drive in it.  Directly above it
    is my PC-AT.  The floppies look pretty similar.
     
    Can I write data on one machine and read it on the other?  There appear
    to be formatting problems with making this work.

I tried reading a MS/DOS floppy on my Apollo (/dev/fl0a) and got format
errors.  Aegis wants DSDD, 1024 byte sectors.  Anything else and you're
out of luck.

I think you may be able to do this if you have a Kiwi (MS/DOS) card.
It might talk directly to the hardware.

    I have a package that is designed to read/write MS-DOS floppies from a
    UNIX system.  I'd like to port it to my DN3000.  Anyone done this?

It should just port over with no changes other than the name of the
floppy drive.  But it won't do you any good if you can't get the bits
off the disk.

The right way to do this is with an extensible streams type manager,
so that the MS/DOS file system looks like it's part of the domain
file system.  I have a manager that does this for bsd4.3 file systems
if anyone wants to use it as a model.
