Cassette-less Tape Based DuoFone Answering Machine 1970s

From the 1970's (I owned mine in the 80s originally) comes this amazing little answering machine. There are no cassettes! No Compact Cassettes, no MicroCassettes. But! There IS cassette tape hidden under its sturdy plastic cabinet. Also, there's no power cables, only D batteries! Unlock the mysteries of how this machine works in this video from databits. Radio Shack made the coolest DuoFone devices!
