Regarding use of an ST-251 drive with an RLL controller:
	*Don't*!

With an RLL controller you need a drive with tighter specs than you
need with an MFM controller. You *may* get away with using a non-RLL
certiified drive, but you can't *count* on it.

The ST-251 is only certified for MFM use. The ST-277R is a ST-251 that
is certified for RLL use. It works well.
