last month I posted a question about why my Mac IIfx seemed to be running slower than the Mac IIci. I got an answer: The memory manager code in MacOs seems to have a problem on the IIfx. Apple has an INIT called MMInit which takes care of the problem. Presumably anybody can get a copy of this from Apple or a distributor for free. Ed ekalenda@cup.portal.com

There was an article recently from the guy at Apple who wrote MMInit. His basic point is that MMInit is a hack, and is only needed for the users of one or two applications that are bitten by the Memory Manager bug, which ONLY hits those apps that allocate large numbers of non-relocatable blocks. He says that MMInit is known to cause an increase in the frequency of system crashes, and that if you're not running those particular apps (sorry, can't remember their names) it would be better to wait for System 7, which fixes this and other bugs. BTW, the bug exists on all machines with the 32-bit-clean Memory Manager (IIci, IIsi, IIfx, also LC I think). -- John Cavallino | EMail: jcav@midway.uchicago.edu University of Chicago Hospitals | USMail: 5841 S.
