Re: Apple SCSI

Does this have anything to do with SCSI 1 and SCSI 2?  I
had the same problem with getting the Mac Plus in seeing
a SCSI 2 drive.  It would format it and I could load the
system onto it but when I rebooted, it didn't find the drive
anymore.  I took the drive back and got a SCSI 1 drive
and it worked fine.
