Howz about drives for use with SCSI-2 systems? SCSI never defines the data encoding on a drive. It's really independent from the data encoding. The SCSI BUS transfers bytes, not encoded data. The drive itself has to deal with the encoding. The bus is completely independent from data encoding. So it's possible, to not even connect disk drives, you can also connect tapes, printers, scanner, or whatever you think about.
