I have just purchased and installed SE and Plus 40 MHZ Gemini Upgrades and
only the Plus version gives you a "new" SCSI interface.  I don't
know if the SE version increases the speed of the "standard" interface
but the Plus version gives you a whole new connector.  I believe
that the Plus is missing some SCSI handshaking that the SE and beyond
already have.
