Re: AM6012 DAC replacement (Tempest)???

        I didn't see that anyone replied to this message, but I could be
wrong, so if this is redundant info, sue me... :)

        The Tempest schematics show the board with both the 3410s and the
6012s. So, for all intents and purposes, the MC3410 is a replacement for
the 6012, in Atari Color Vector boards. As far as I know, all of the
boards have the "option" to be populated with MC3410s (and there are some
other circuit differences.)

        I don't think MC3410s arereally any easier to find them AM6012s,
I'm afraid...
