I will be renovating one of these next week, owner from new, was told only
100 came into the UK, probably 1982 from numerous IC "2.." datecodes. What
is the use for the "sound processor" as no display, but seems to have its
own 3V batteries for memory retention.

The front comes away easily as do the 2 tape decks, hopefully just perished
rubber bands and minor owner-mangling problems

If it is 1982 it uses a very early minidin connector, 8 way, to connect the
umbilical to the music processor (not sound processor)

I was working for a retailer that sold the large Sharp boom boxes in
1982 and never heard of this model. Were these sold in the U.S? Chuck

Surprisingly few hits on Google so presumably rare. Latest date found was
number
..21224-A on a Sharp deck motor , presumably Dec 1982 , so shipped 1983.
Other motor had .21127-A

Back working again with all 7 bands replaced with new silicone rubber bands.
I wonder how long they will last. I read last week that silicone rubber is
not as tolerant of cyclic loading, which dynamic use of this material I
suppose is so, especially around the smaller drive bobbins
