Subject: The Opus Challenger disk system

Does anybody have any programming information about the Opus 
Challenger disk system? I know it used a 1770/1772 disk chip, but 
apart from that I've no idea... I'm especially interested in finding 
out how one might actually get at the disk controller registers, 
since I want to play with a real 1770 before having a go at emulating 
one.

Any help would be much appreciated, but apart from that it would be
nice to know that there's someone else out there apart from me who
has one of these :)
