[sdiy] TI 76477 Space Invaders sound chip detailed analysis

[Adam Inglis]

Whoah! 
Heavy stuff! 
Fabulous textures. Love the stereo separation.I assume the TEAC reel to reel is contributing a lot to the sound?

Putting up posters with schematics on them - that cracks me up!!!

>>    It had several clocks to connect to the select pins--by doing this, you could get several sounds at once. The controls were a joystick, a trigger button, three or four multi-pole switches, and several potentiometers. It was never quite clear what sound(s) you were going to get, but it was often interesting. And always crude.
