We've found the 1140 to be "expandable" to 2190 specifications with very
little problem, except that DOS can't access more than 1024 cylinders.

So, we've put Adaptec 2372 RLL controllers on 'em and they work just fine.
The 2372's map the cylinders so DOS thinks it's playing with a 1024-cylinder
drive.  The nice thing about a 2372 is that it will do _it's_ surface
verification test and map out individual sectors instead of wiping out
an entire track.

That's right: RLL on the Maxtor 1140 running to 1224 cylinders.  As I recall
it's good for ~240 Megabytes, formatted.
