Will the SunOS 3.5 "xt" driver binary allow two 1600-bpi tape drives on
ONE Xylogics 472 without overflowing any internal arrays or exceeding
other limits in undetected ways?

If so, can one drive write while the other is rewinding, or must it wait
for the rewind to finish?

(The Xylogics 472 is designed to do this, but the "xt" man page only
illustrates the controller-per-drive configuration that Sun sells).
