[sebhc] HDOS Issue #50.05.00

[Steve Thatcher]

actually, the sector hole hardware was one person's work done a while back. 
I was proposing a circuit to do the very thing that has just been suggested 
again. I see no issue with speed variation being a problem. I just don't 
have time to pursue it at the moment.

best regards, Steve Thatcher
