It's getting harder and harder to find motherboards they'll even fit into let alone function properly. I've seen a lot of different permutations of not being able to fit a full length card in... either the CPU, or the simm banks or a head-sink/fan are in the way. Now the newest problem is that manufacturers are taking isa slots off in favor of pci slots, and putting crap in front of the isa slots so that you could put a full-length pci card in (if they existed) but not an isa card. :( Full length cards seem to be a thing of the past. >Is anyone aware of some PC AT spec that limits >the bottom dimension of a full width card?

And on top of it, I would also guess the screwball engineer got a promotion or something for `ingeniously' cramming the motherboard into a smaller footprint. > >Paul >-------------- >Paul Werkowski ANSI Common Lisp on Intel? >pw@snoopy.mv.com http://www.mv.com/users/pw/lisp > eric. -- erich@lodgenet.com erich@rrnet.com
