For sure - No earthly reason to use an Emulex unibus controller in a
750 unless you maybe happen to have one lying around.  There's a SC750
somewhere in the guts our olde 750 and other than the drive cable
paddleboard falling off cause somebody lost the bracket, it's been
running since the machine was born - ~5 years, ~3 sites ago...

SC750/7000 = 1.8 MByte/sec - Eagle Class, SC7002 = 2.5 MByte/sec - just
about anything - SC7003 3.0 MByte/sec XMD-III and other scorchers...
