I'm not the ultimate guru on this, but I strongly suspect the ROMs are not interchangable regardless of the pinouts. The ROMs will contain hardware-specific code that will differ for the SE/30 and the IIci. ========================================================================== Rick Holzgrafe | {sun,voder,nsc,mtxinu,dual}!apple!rmh Software Engineer | AppleLink HOLZGRAFE1 rmh@apple.com Apple Computer, Inc. | "All opinions expressed are mine, and do 20525 Mariani Ave. MS: 3-PK | not necessarily represent those of my Cupertino, CA 95014 | employer, Apple Computer Inc."
