What I need to know, is how the mac does it - ie not what lovely rom calls there are, but what the hardware needs & does - ie is there a lovely sound chip that does dma on a pcm map, does the processor have to stuff it byte by byte, polled - interrupt - in short *how* does it work - when I know this I can tack one on to a lisa (now you see why) - I am quite prepared to write the patch for the os to use it and not the internal system but I have to know that it is feasible first ! Then I can dive into IM and produce the new calls ... HELP Please !!!
