commodore outsourced their custom chips asswell.
to hitachi and toshiba look on the chips. some were made inhouse. outsourcing is no new thing.
just about all the custom chips of the ps3 are outsourced. even the mobo is built by others to sony specs.
the ps3 is what the latest amiga should have been in ALL aspects. except we would probably be at os12 by now.
sigh. the amiga is in the land of the thumb twiddlers.
