is the driver for the Integrated Solutions QIC-02 1/4 inch cartridge
tape controller.  The
driver supports a single tape drive per controller.
Controller 0 is assumed to be at address 0xfff550 in VME A24 supervisor
address space (address modifier 0x3D).  Controller 1 is assumed to be
at address 0xfff560 in VME A24 supervisor space.  The user may access
other tpqic controllers with control registers at addresses other than
these by specifying the negative of the control register base address
as the controller number.
Currently the
driver supports no special ioctls.
