[sdiy] Anyone ever use an AY3-8910?

[Eric Brombaugh]

Software emulation sounds interesting.

That reminds me of another ancient computer that I have - the Mindset. 
This was sort of a DOS-based pre-amiga with lots of nifty AV peripherals 
built in. It has a custom-programmed 8048 microcontroller set up as a 
dedicated sound processor. It hangs off of the system bus and has a pair 
of DAC 08s, a 4-pole lowpass anti-aliasing filter and audio jack . Back 
in the day I spent some time reverse-engineering the register map and 
found all sorts of interesting sounds that it could make. There are 
several modes of operation, including 4 sine oscillators with FM, 2 sine 
osc + noise, or 6 square oscillators. Envelope generators and mixers too.

Of course these days things like AVRs and FPGAs make more interesting 
stuff possible.
