Hello CN,
Looking for some pointers on how to go about fixing my G11 Gemini 1 Controller with RJ cables and not round connectors.

 

I have been using this mount for almost forever though considered myself as second owner for over 12 years. The controller hasn’t been perfect for past one year or so with CMOS battery. Every time I put a new battery it will stop booting so for some time now I have been using my laptop to load location and other settings via serial port and recently that also stopped working.
Upon inspection discovered a dead spider inside and a burnt resistor. Question is if the old motherboard is salvageable and who can fix or shall I start look for an upgrade?
Any suggestions will be appreciated. Thank you, Ansuman.

I don't have the skills to fix a PC board, but if you do it doesn't sound like you have anything to lose by trying.

 

Losmandy will sell you a Gemini II controller for $600 if you send in your old Gemini I.  At least that was the deal when I sent my Gemini I in last spring.  You might want to call and double check that the deal is good whether your Gemini I is working or not, just in case your fixes don't work.  Losmandy will also double check your cable inventory and make sure your servos will work with the Gemini II.  Or maybe that's just double check you have servos and not steppers.  Why you'd have steppers and a Gemini, I don't know.
