Would the macintosh boot up >software identify a problem with the SIMMS? The additional time required at startup is required for the Macintosh to test the additional memory you've added. To confirm that this is the case, however, try _restarting_ (instead of powering off and then powering on) and see if the Macintosh is still slow. The Mac does a memory test when the machine is started up cold, but not when it is restarted from the Finder (restart command), the monitor, using the programmer's switch, etc. -- David Walton Internet: dawyd@tartarus.UChicago.EDU U.
