Unfortunately, |the only instructions that came with the little stinker were to have it |installed by my local Apple dealer (fat chance...). Can anybody tell me |where to plug the thing in? Where does it go? On the Mac II mother board, there are three large sqaure ICs. Two have gold covers (like the PMMU), while one is in an all-black package. The two with the gold covers are the 68020 and the 68881. Remove the all-black IC and place the PMMU in its place. You can remove it by very-very carefully lifting the edges with a screw-driver (lift each edge just a little at a time so the chip lifts out evenly). Then press the PMMU in it's place, again very carefully. Jerry -- Jerry Whitnell jwhitnell@cup.portal.com ..!sun!cup.portal.com!jwhitnell
