sim interface for AM Tx for FMS
 

I have FMS and was wondering if my old AM Tx's (with no buddy-box plug) could be converted and used as controllers.

Obviously, I would need to build a special interface between the tx and my computer.

I can solder ...BUT... I need info on how to go about finding pinout info ... and locating all the correct connection points on the circuit boards of Tx.

Anyone out there ever sucessfully do this?

recap: I want info on hard-wiring a simulator interface to an old Am Tx.
