The CEM3374 seems particularly hard to get. Is this actually true or
was the $200 chip on ebay a while back just dumb auction activity? It
also seems like a good choice for reproduction. It gives two VCOs on
one chip designed to work with a micro. If they were available it
would put interesting polysynths with real VCOs back in the DIY realm.

The Korg AD2069 is a fantastic filter. Does anyone have any insight as
to what's inside?
