Are there any tables showing the DSP versions of these cards? I can see lots of lists of CTxxxx chip/board numbers, but not DSP versions. From what I can tell, for DOS-compatible cards (AWE32, 32, AWE64?), they all have a DSP major version of 4 and support the SB16 interface, is that right?

No DSP versions, but there's a list of DSP chips - Sound Blaster: From best to worst
Anyway, yes, AWE32/32/AWE64 are all just SB16+EMU8000, so it's all DSP 4.xx

Much obliged. 😀

Here is a link to the archived AWE32 SDK and documentation:

Thanks, cyclone. That organisation diagram on page 9 of the DIP also seems to answer something I was curious about - the wavetable output is combined into the FM output and becomes the 'MIDI' input from Mixer's perspective, if I'm reading it right? I don't own anything beyond a SB16 myself, so I'm not familiar with it.
