- Actually, the byte-swapping was an artifact of using a bigendian CPU
- (680x0) on a little endian bus (Multibus I). The first tapes that were
- "right-side-up" were SCSI peripherals. We also found a simple change
- to the old tape adapter card that would make it "right-side-up", but
- decided not to put it into production. We had too many variations
- already.
