The difficulty is a problem with the Mac Plus ROMs.  This was a problem only
with Mac Pluses that aren't platinum (No, it has nothing to do with the color
of the case, it just happens that Apple changed the ROMs at the same time that
they changed the case.  Any SCSI drive connected to one of these Pluses must
have the 'Unit Attention' feature disabled.  Because of Apple, most drives have
the option of turning this feature off.  Also because of this, if your drive is
not up to speed and ready when the Mac Plus looks for it, it won't boot, you
have to press the reset switch.  I won't explain exactly why this happens,
because it isn't that interesting.  Suffice to say, the Platinum Plus will work
with any hard drive that the SE will.  But the SE will do so more than
50% faster.
