 |
|
I have a Fisher 701, this was an early Quadrophonic (4channel) receiver unit.
I opened it up to have a look, and saw the following tiny Motorola chips on it:
a) SC5182P also marked 7021
b) 7021
c) 7036
d) MFC 6010
I figure these are some sort of simple sound chips, or maybe used for transistorized radio reception ... but can find ZERO about them in the search engines I have tried.
Era is early 70s (RCA introduced quad sound in April 1970). |
