So I've also been taking a look at the DMA capable P82C612. This is what the MCA Sound Blaster used so I've been seeing if maybe it could be used to make something more capable than an adlib clone. So far I've been playing with the idea of connecting it to something like an ES1668 which is what the Sound Piper and Chip Chat cards used. So far I've come up with this:
Again the same things apply, I'm basically just playing connect the dots between the data sheets and would need someone more experienced to step in and check it. Also this is just the connections between the MCA bus, the P82C612, and the ESS chip. There's nothing for the output, mixing, MIDI/Gameport, External Wave Table, etc. Also not all of the POS stuff is really figured out either. I don't think it would be too hard though, as there's tons of examples in the P82C612's data sheet.
