BUSCOM SoftTouch AutoDialer Model 23

Circa 1982

Designed to add touch-tone dialing and memory functions to traditional rotary-dial telephones. It was an ingenious solution for users who wanted the convenience of modern phone services (like tele-banking or credit card verification) but were still using older, rented rotary phones.

Key Features:

• Touch-Tone Conversion: The device could be attached to a telephone's handset (often replacing the microphone screen in G-type handsets) to provide push-button, touch-tone functionality.

• Memory Dialing: The Model 23 had the ability to store phone numbers, allowing users to program and dial long or frequently called numbers easily. The keypad includes buttons for "MP-1" and "MP-2" (Memory Position) and a "REDIAL" feature.

• Power Source: It was a clever device that was powered by the current of the phone line itself, meaning it did not require external batteries or power adapters.

Installation Steps:

• Remove the Mouthpiece: The user would unscrew and remove the existing plastic microphone screen/mouthpiece from the "talking end" of their traditional rotary-dial telephone handset.

• Attach the AutoDialer: The AutoDialer is designed to screw directly into the body of the handset, replacing the original mouthpiece.

• Use: Once physically attached, the device uses the existing current from the phone line to power its internal electronics, allowing the user to make touch-tone calls from their old rotary phone.
