Acoustic Coupler for Use with a TRS-80 Microcomputer


An accoustic coupler made it possible to link a microcomputer to a telephone line, converting digital signals to analog ones and vice versa. This acoustic coupler was specifically intended for use with a TRS-80 Portable Computer. It has two rubber and plastic covers that would attach to the outside of the speaker and microphone units of a telephone headset. A coupler cable joins to a DIN connector, which would fit into the microcomputer.

This acoustic coupler is in its original box.
