	Without getting coarse, Scott, I (and many others) would greatly
appreciate it if you would explicitly quote the manual and not simply ask us
to take your word for it.

	I have inspected my hardware manual, and the only thing I can find
that might possibly be related to varying bit densities on the disk is the
ADKCON register, bit 8 (FAST).  This bit switches from 2 to 4 microseconds
per bit cell.  Was this what you were talking about?

	I presume you mean it turns on (300 rpm) and off (0 rpm).  I see no
other software controls to vary speed in the manual.  Am I blind (I
personally don't think so)?
