Description

The object is an acoustic coupler modem built in to a wooden case. There is a carrying handle on the top of the case. The top swings up to open. On the back of the object is a power plug, and RS-232 connector, and a fuse. A sticker on the bottom of the object indicates that it was repaired Aug 16, 1972.
