Peter,

The Media Control Set is documented in the "Programmer's Reference For 
System 6.0" by Mike Westerfield.

There is also a 2 paragraph clarification for some of the finer details 
found in the "Programmer's Reference for System 6.0.1" (also by Mike 
Westerfield).

I got both of these included in the documentation that came with "Opus 
][ - The Software" (download edition) which I bought a few years ago 
from Syndicomm.

I personally haven't tried to write one from scratch, however I did play 
around with some media control drivers source code that was supposed to 
allow the Apple High Speed SCSI card to control SCSI-2 cdroms a while 
back. I could never get it to work though - I think there was another 
driver required that I don't have :-( .

Anyway, I hope this helps.

Cheers,
Mike
