Somebody have > a 601 or specs so they can check into this? IIRC, the 601 has *more* instructions than the 603, as it was supposed to be compatible with IBM's POWER instruction set. This ended up causing a great deal of performance problems when the 603 came out, since these instructions generated exceptions that were handled via software. It's been a while since I've looked into such things, though. You might want to check out Motorola's web site, as they have manuals for all those chips available for download. HTH, cbb
