I find that with almost all chips, the first alphabetic characters usually imply ONLY the manufacturer. So I looked under 3306 and found the above. If I recall correctly, the prefix C (as in C3306) implies RCA. Hope this helps. Aaron Michael Chesir ..att!twitch!aaron AT&T Bell Labs 1-(201)-949-1530
