If you read the manual, you will find that in the later versions of SCO
XENIX, you can specify the interleave. A 1:1 interleave speeds things up
tremendously, if you controller can handle it.
Sorry, but I'm not sure when that feature was implemented, and I don't have
my manual handy right now to give you the switch setting.
