Looking at the chips on this Gold version, can someone please tell me what they do?

The two chips near the RAM extension header pins must be the card's onboard RAM, to hold the SoundFonts.
I'm guessing that the CT1745A-SCP is the "mixer chip". Were there different revisions of this chip on the AWE64 line of cards?
Does it have a discrete DSP chip?
The EMU chip seems small, compared to some of the other chips. That's curious.
Finally, not pictured, but off to the right hand side, is a 9 pin header. What's that for please?

Thanks a lot for any info! 😀
