My TM 500 extenders were supplied as a kit from Dan Meeks (though I doubt he has any left) and the ribbon-cable is ~87 cm long. I can't say that I've seen any problems with oscillation of the pass-transistors in the mainframe, but wouldn't they need to be connected to some circuitry in a plug-in at the other end of the extender? I can't see how an unpowered transistor can oscillate.
