Yes. Yes. Of course. If that's the cheapest way to go, then do it. If it's not, then go whatever other way gives you more bang for the buck. If you have your own silicon foundry and are already designing a bunch of custom chips to get the part count down, then what do you think you'll find? 680[23]0s are *not* cheap chips. -- Peter da Silva, Ferranti International Controls Corporation, sugar!ficc!peter.
