[sdiy] Does anyone have the Roland IR3109 datasheet? (looking into sh-101 filter modification)

[Julian]

Or even some decent jupiter 8 schematics?

Or... ; )

What im trying to do is work out if the sh-101s IR3109 can be switched into highpass.  I know the jp8 has highpass, and uses the 
IR3109 filter chip, but i think it uses some other filter ICs also.

Does anyone have any of the literature, of has considered this before?

Thanks,
Julian
