  I'm confused about memory expansions for the Mac Plus, and SE. I've heard
the terms 'high-profile' and 'low-profile', as well as discussions of memory
speeds. Is high vs. low profile just a matter of how they're mounted? Can
one use either high or low profile SIMMS in a Mac Plus, but only low profile
in an SE? 
 I thought I remembered someone saying that the Plus took SIMMs with a 
different speed (150 ns?) than the SE (120 ns), is this correct? Can a Plus
run with faster memory? 120ns? Can an SE run with slower memory?
  I'd appreciate any light that people can shed for me.
        Thanks,      
                  Jai
