As an aside, SCSI-1 wasn't quite so tight, or possibly wasn't followed
quite as closely.  Trying to move hard disks (not something as
esoteric as CD burners) between systems was a hit-or-miss
operation. You'd get disks that didn't spin up at all, or systems that
would keep restarting the drive while trying to boot, never getting
anywhere.
