Well, we have a set of 9tracks and a pair of TA90's, a VMS CI VAXcluster,
and an Ultrix CI Clump, both with HSC's.  We put an HSC5X-DA into the
VMS HSC (HSC1) and an HSC5X-DA into the Ultrix HSC (HSC2), hooked the
A port on all the tapes to the VMS side, and the B port on all the tapes
to the ULTRIX side, and now both machines have a substantial tape farm.

Note that you have to prevent either side from monkeying with the others
tape, or have the operators push the switches a lot, but it works
quite nicely.
