I have a multi-processor UNIX OS that I have ported to the '386 AT systems, and I can not use its multi-processor features until one of these machines come out. We are building an OLTP product using 33 MHZ 386 motherboards, and want to upgrade to multi-processor as soon as I can get hardware from someone. JR
