anyone knows the vcp ( video display co processor ) v99c37 ,was it included in v9938 or was it additional chip ( for digitize ? ) ?
i found it just by googling around ... some japanese post say it is connected on color bus and is used as pallette , in that case i wonder if the registers you that palette can be written through v9938 bus ...

i suspect v9958 as it included with the yjk/yae modes ...

I obtained the Yamaha's ad for V99C37 mentioned in the Wikipedia, but the only information there is it's "V9938's coprocessor". Here
I don't know what kind of graphics V99C37 could display and I no longer own the Captain Multi Station, but the Captain System graphics were like these so it had been comparable.
