I was given a whole bunch of old Sun and HP hardware. I want to know if I can fit a ST39173WD drive into either a Classic or a Sparc5. I know next to nothing about SCSI. The motherboards have 'normal' SCSI connectors but the hard drive has some sort of SCSI-3 interface. Can I use this drive on either of these motherboards? How? If I can do that, I then want to connect a SCSI CD ROM drive whih has a 'normal' SCSI connector on it.
