Yes, I have written the driver with the information they have given me.
They have been very helpful. They even supplied and shipped 2 N2 boards
and a N2pci board from the USA to me here in South Africa.

The bulk of the driver has to do with the Hitachi HD64570 chip that the
board is using and that information is in the Hitachi data sheets. The
information about how the chip is interfaced to the rest of the board
is actually very little, because most (all) of the work is done by the
chip. The rest of the board is actually just RAM, bus arbitration logic
and line drivers.
