No clue Bob.  And I suspect but have no proof that if the os9 copy program 
tries to emulate the wd1773 too closely, then it will run into the fact 
that the track and sector registers in the WD1773 are byte wide, tracks=max 
of 255.  Ditto for sectors.  I haven't looked at that code as it seems to 
Just Work on linux.  But it could be enlightening to look at the code with 
that in mind.  You are still building on the R-Pi?  That of course throws 
another unknown into the morning oatmeal.
