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. John -- John Hay -- John.Hay@mikom.csir.co.za
