I've got a Denon 12 cassette changer in my collection that I have
absolutely ZERO outside information about. Front panel says
Cassematic-12. Rear ID panel gives a model number of TRC-798ED. Unit
appears to have been made early 70's but I've never heard of a
cassette changer dating from that period. Unit is about the size of a
shoebox. 12 cassettes are loaded into a carrier on top of the unit
and as each tape is advanced, it is lowered into the cassette
mechanism and played. After playing, the cassette is ejected from the
mechanism, raised back into place in the carrier, next tape advanced
and then the whole process starts all over again. I can't even find a
single reference to this oddity ANYWHERE on the web, including the
newsgroups. Almost forgot...unit plays and records.

Email me if you want some pics of the unit. Somebody out there is
bound to know something. It'll be on Ebay pretty soon but thought I
might try and get some information on it before parting with it.
