1488 and 1489 are correct. (MC1488 MC1489) Radio shack used to carry them. I get mine from DIGI-KEY now. $1 or so each, no shipping charge on my last orders! I stock up every April! Same chip used on 200 analog and 200D '036' MCC. Get a few 14 pin low profile dip sockets. That way, if they get blown again. no more soldering iron, just unplug and plug! smile


When I was young, I was Liberal. As I aged and wised up, I became Conservative. Now that I'm old, I have settled on Curmudgeon.
