AW: Duophonic Keyboard

[Haible Juergen]

Does anybody have the schemos for the Oberheim Two Voice keyboard ?
I'm aware that it's very similar to the OB Four Voice keyboard, but I think
it is *not* just a Four Voice overhead logic board with two voice logic
circuits (rather than 4). As far as I've heard, there are some minor
differences.
Anybody knows for sure ?

PS.: Allmost forgot to mention - yes, this should be two really independent
voices !
