OK, but there is a very simple reason that the AP2544-02 doesn&#8217;t work in your Power Mac 6100 or 7100 (8100 or 9150 either). That SIMM is the Cache + ROM card from a Performa 6200, and possibly also the Performa 6300 and related machines. Don&#8217;t put two ROMs in your computer, it probably wont like it very much.
