I can't forget because I never knew that! I'm not always that interested in IBM 3x0 systems, but that's a really cool concept. I'm guessing they were microchannel boards that plugged into the IBM PS/2 line ? I can't believe IBM would have let you run them on any old PC (given the clone wars at the time). That blows my mind. I always thought it'd be cool to be able to extend a standard SGI system with a compute brick from an Origin. In some ways you could use a craylink setup to get close, but nothing as cool as an add-in board for a whole 'nother platform. -Swift
