Ray,

The board uses a cb7210.2 chip, which takes up the first 8 io
addresses, and for which some docs are available at

http://www.measurementcomputing.com/cb7210/

It also uses a cbi488.2 chip for its high-speed mode (it doesn't need to
be used for nec7210 compatibility mode), which takes up offsets 8 and 9
from the base address.  I have a fax with some cbi488.2 info in it, but
haven't converted it to electronic form yet.

What version of the driver are you working on?  I've made a lot of changes
to the cvs and it might not be worth spending much time modifying the
older versions.  I am rolling support for all the computer boards stuff
into the generic nec7210 driver, which is currently working (on and off as
I make changes) with my isa pc2a board.  I put some support for the
computer boards PCI-GPIB but I'm not sure if that's working yet.
