  I'd be ***REAL*** interested in any such machines. 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.
