Try man tps MAKEDEV.  One of the advantages of buying from us is that
you get documentation.  We make links to the byte swapping device
by default (ONLY for QIC tapes) to be compatible with the older 68k
machines which had a byte swapping controller.

If you do:
	su; cd /dev; rm *tape*; ./MAKEDEV tps tapelinks
then your /dev/tape will point to the non-byteswapped fixed block
device.

Life would be so much easier if we could just look at the source code.
