What is a "slow" SCSI interface.  I'm guessing you mean the 98658A plug-in
card vs the 98265A daughter board.  The plug in has a max speed of 2.5
Mbytes/sec., vs 4.0 for the daughter.

HP (HP-IB) cartridge tape drives use the 3M HCD format, not QIC.

Is a high-speed HP-IB installed?  If not, you may discover that swapping
over the net is faster than via the standard speed built-in HP-IB.  Was
there any particular reason you are not using SCSI on the 340s?
