Begin Edit:
I think I can answer my own question. The 5 main chips are:

OttoR2, Sequoia and MC68EC000 are the main chipset sound processors.
There is also the 2MB ROM sample set.
Plus the SoundPort chip, which is covered by the Reveal sticker.
I'm not sure where the AMD InterWave chip is though.
End Edit.

Can someone please identify the 5 main chips on this Reveal Sound FX Wave 32 wavetable sound card, which is similar to an Ensoniq Soundscape, but it also has hardware tone controls, and 3D spatial effects.

In other words, what do these 5 chips do? (The fifth chip is just off to the right, with a white Reveal sticker covering all of it.) Thanks very much people! 😀
