Wow I am so glad I found this topic! I recently purchased a Celestron CG-4 EQ mount with motor drive and it comes with the exact same hand controller. I've used Arduino's for a number of simple projects and also keen to integrate one at some point, will let you guys know if I get it right.

Scares me a little that this controller is not very reliable, thanks for the heads up... going to look at adding a voltage regulator ASAP.

Regarding a reader/programmer for the chips this controller uses, you can build one using an arduino... quick google shows this
