Dave,
 I have talked Microware out of source in the past and severely altered the
Z8530 driver for our MVME147 system. I can't upload it as it is still basically
Microware's copyrighted source. What you *can* do is disassemble it with debug.
You will obviously have no symbols, but it might help. Maybe the people who
sold you your system will give you source to the drivers you do have. You are
correct in assuming they will be very similar, though the device set-up and
configuration stuff (eg: baud rates, bits/character) can be challenging,
especially if you want to provide hooks (setstat()'s) to change them on the
fly.
 That was 3 years ago. Since then, we wrote our own block-oriented file manager
(for protocol conversion) and *every* device driver I have written has been
doing some protocol's level II under *that* file manager.
 Good luck!
 Mark
