Mark, I have been using the 10 Meg B-Box on a Tandy 4000 running
Xenix 2.2.4 for a couple of months now with no problems (once I
got the switch and jumper settings correct).  I use it primarily
as a mountable file system both for incremental file backups and
development work.

I am using the Tandy supplied dcd interface board, but they have
dropped this from the catalog.  The same board is available from
Iomega.  You need to get Tandy's Device Drivers (catalog number
700-1502) to support the B-Box.

These drivers use the same interrupt level for the cartridge as
the second parallel printer port.  DO NOT USE THEIR OPTION TO
REMOVE THE PRINTER DRIVERS!!!  This doesn't just remove the
second printer driver support, but all parallel printer drivers
are dropped from the kernel.

I have been very happy with the flexibility I have with the
Bernoulli Box, both on my old Tandy 6000 and the current Tandy
4000.  You might also consider getting an a-b switch so you can
use it with both systems.

Bill.
