See if your version of Linux supports Digiboards. If so I have a bunch but I will need time to make a list. They are 2, 4, 8 and 16 port version and the 8 and 16 port ones that I have played with so far you can run with either no interrupts under NT4. I only have a few cab kits however so you may have to make a cable set. I think I have the pinout info. Contact me off list for further details. Dan danburrows(a)mindspring.com dburrows(a)netpath.net
