Hi Joe. The controller I just purchased from Meade is the one that comes with the scope,#35-4702-00, mine was missing.
Actually I purchased it this way. Not knowing the condition of the mount I thought I would buy this one first for $20.00, test the drives and then buy the #497 which apparently will work.
I'm glad I did it this way, even though the scope is in perfect condition I think it has a motor control problem, you can see the symptoms a few posts back.
