Korg 03RW,01RW PCM interface schematic?

[Barry L Klein]

Anyone have schematics of the Korg 03rw, 01rw, and say Wavestation SR? 
I'm curious if the synths actually use the same TG-88 interface/wavegen
chip, and thus maybe the same data format.  If so, I'm curious if the data
format may actually be the same and pcm cards for older synths could be
used with newer synths with the right "glue logic" in place.  The newer
synths use more common pcmcia format cards that might be readible in the
available readers for the pc (really intended to r/w cards used in digital
cameras and laptops).
