Well, I wasn't going to post anything in response to the original question about side mounting since I figured lots of others would. But this note needs a retort: While the nubus cards are not supported at both ends, they dont need it, they are very stable because they don't use edge-connectors. The connector on the card (male) has three rows of seperate (relatively thick) pins which fit into three rows of matching holes in the female connector on the mother board. The Mac II (at least mine) is absolutely pleased as punch to be on its side, as long as you don't block the fan vents. do see one small unfortunate fact. Because the fan is on the side that faces down (since the floppies and hard drive are on the other end) and since it blows outwards, the fan is now fighjting the natural convection cooling. It wouls be nice if this could somehow be reversed. ------------------------- Josh Hodas (hodas@eniac.seas.upenn.edu) 4223 Pine Street Philadelphia, PA 19104 (215) 222-7112 (home) (215) 898-9515 (school office)
