This chip doesn't go easy on the I/O lines, though. It's made for PC
and game console-type architectures (I'm pretty sure it was used in the
Amiga, and several Atari machines, for example). It generally requires
the use of a data and an address busm which is fine for an 8 or 16-bit
uP system, but stretches a microcontroller-based system.
The sound quality is excellent, though. I have several of these,
purchased when Radio Shack sold GI's surplus product.
