AKA Radio Shack DuoFone 93T? Well, I've got one that had been re-jumpered to work with a key system. I want to un-modify it now to operate on a single line. Of course I didn't document the original modification! Does anyone know what the jumpers inside should look like? There are two sets of pins: one set has three pins and one jumper; the other has six pins and two jumpers. Thanks for any help. scott
