There isn't a link. MSR stands for Metal Skull Robotics (Inventor, Dutch roboteer). those drives are in Satanix and one of the Beauties, as well in several other machines. The 12-54 is the fastest in use to date, the 16-50 will be insane.

And the source of them , currently, is me. 1 problem, I don't have any speed 900's to spare.
