Tandy Radio Shack TRS-80 Acoustic Coupler AC-3. An acoustic coupler is a device that allows a computer to transmit data over a standard telephone line by converting digital signals into audible tones and sending them through a telephone handset's speaker and microphone. The coupler physically holds the handset in rubber cups to minimise background noise and ensure sound transmission. This device was originally sold for $149.95 and was advertised as being ideal for travellers because of its relatively compact size, for the time.
