  I'm looking for the documentation for the olde TI
analog
...
  sound chip; this dates back to the late 70's early
80's if
...
  my memory serves me correctly.  I don't even
remember the
...
  part number.  AFAIK, it had some kind of
"I2L" (I squared
...
  el) technology or somesuch, and it was mostly
analog, with
...
  some digital control (but nothing like a DSP or
midi).

...
  Anyone recall this chip?  Anyone have the datasheet
for
...
  it online or willing to scan it in? 
SN76477N,

...
  Background:  I remember playing with it a *long*
time ago,
...
  and wanted to model it in software :-) 
I remember it well, it was the canine gonads until the
AY3-8910
and it's ilk appeared.

Cheers,
	Lee.
