Have you got a PB SCSI cable or adapter?
I have the HDI-30 to DB25 converter, but no DB25 cable
The second USB connector was plugged in a separate bus yes?
Yep, I tried connecting the USB3 end to my MBP and the USB2 to my iPad's 10w power adapter. Drive would power on, but it would not be recognized. Maybe if I boot the Cube or Sawtooth into OS 9 it will work? But again, I need a computer to use to install OS 8 to the HDD.
I'll second bibilit's SCSI Disk Mode solution if you have an adapter or cable for that. You ought to be able to install 8-8.1 from the 605 with a non-Apple ROM'd CD-ROM drive.
Well, if I do SCSI disk mode, that would use the DB25 connector, so no SCSI CD drive could be connected. Also, how do I activate SCSI Disk Code?
Have you got a Parallel Port on an ATX box?
I'm sorry, but whats an ATX box?
