Aha. The 11/780 demands its tribute. ;-)

This may lead to serious copyright problems, even with a "cleanroom
reverse engineering approach". I think BSD has suffered enough from such
problems. Additionaly Ultrix may be that different, that it may be
easier to write somthing new from scratch, than port ancient Ultrix code
to NetBSD.

If "open source" == "BSD licence" this would be a really big help.

Yes. NetBSD has already MSCP drivers. But guessing a bus protocol on
bais of a device driver is somewhat painful. Also guessing is no good
bais for new code. But reading a tech. man. _and_ existing code is very
effective. (One of the lessons I learned while writing the RX01/02
driver. :-) )
