Makes sense, and if that's the case, it just shows how little I know about the hardware... the article in Electronic Design indeed uses a '030 @ 33MHz, though there's nothing about wait states (only about a "retry mode" of the '030). Is 'wait states' all there is about lower then possible processor performance, or at the 11MHz with 150ns memory such factors (if any) don't come into play? (just curious). -Mariusz -- INET: Mariusz@fbits.ttank.com CIS : 71601.2430@compuserve.com UUCP: ..!uunet!zardoz!ttank!fbits!Mariusz
