Hot damn! So the MOVE SR is a bug in the documentation as well as a bug
in the design. And in the *fifth* edition too. Boy, Motorola just can't do 
anything right. :-)

Hmm, I got a ton of flames for pointing out one bug, I hope you don't get quite
as much for pointing out the other. I happen to have this well-tested asbestos
suit for sale - guaranteed flame resistant. Call me and we can talk :-)
