If this is true, I'd appreciate answers to ANY the following questions:
- Why is this?  I though SCSI had a 'format' command.  All you need to tell a
  Sun (using the 'diag' utility) is the adapter board type, the drive geometry
  (cylinders,heads,sectors/track, interleave) and it formats just fine.
- What components does Apple use in their drives?  
- How can Apple sell a SCSI card for the II without bundling it with a drive?
- Is the Apple II formatter more 'generic' than the Mac version?
- Does the Apple II SCSI board use the protocol converter conventions?
- What will I need to do if I hook up the following? 
	Rodime 204E(ST-506)<->Adaptec ACB 4000<->SCSI bus<->Apple
	Micropolis 1355(ESDI)<->Emulex MD21<->SCSI bus<->Apple
