Fast, inexpensive, most of the kinks are out of the driver, but I wouldn't
trust it as much as a mailbox interface board like a Buslogic or 1740.

You might want to see how the next NCR release effects the non-hardware
related bugs (some PCI implementations are icky), and run your tapes off
the same NCR board or a second one (this has worked for some time) in
the same system.
