United States Patent 4630519

has a device that is based on the LM8972 
possibly, some of the technical drawings will give a pinout.
I believe it was an old Sanyo chip (last seen in 1991).

I have a soundmaster SR-1 which uses an LM8972 rhythm generator. I'd
like to find a datasheet for the 8972, or at least a pinout. Can
anyone point me in the right direction?
