Are AUI to AUI Null Cables Possible?

Mike Harvey asks: "Hi, after obtaining a SparcStation 1 I realized I have no way to connect it to my network. I know I could go out and buy a transceiver for it, but, as one of the really poor students of the world, I was wondering if it was possible to do an AUI to AUI null (or crossover) cable, and whether it would work to connect it to a second net card in one of the other computers? I could just try it, but I would prefer not to make either into paperweights."
