The Mac IIx, IIcx and SE/30 do not require all SCSI devices to be powered on to boot. They DO require proper termination. The drive I had connected had an internal SCSI terminator which only works with power on. To allow booting from the internal drive with the external drive powered off I added an external SCSI terminator. My advice is to spend the $18 or so and add the terminator so that you have the option. Roger Corman
