I understand that a Western Electric 1C2 phone can be wired for home use by jumpering Pins 5 and 8 on a plug (see video at https://www.citizenengineer.com/ at 13:10 in). I do not see this plug on the 1D2 phone pics I have seen posted on the internet ( https://www.flickr.com/photos/kd1s/3055173054/in/set-72157609985193036/ ) - only the plug for the keypad/front panel. Does anyone know what needs to be jumpered/ modified to enable a 1D2 for home use? I have been looking at a 1D2 phone for possible purchase (not modified). I want to keep the original coin mechanics inside (for historical purpose) but do not mind if it is disabled.
