I also have a large quantity of Sphere docs and a big pile of hardware, but it was part of a deal with Jim Willing that went bad. I have tried to get the stuff back, but he is not responding. -- It's probably sitting next to the Tektronix 405x documentation I never received. I don't think short of you driving to Kansas and watching him go through everything that he still has that you will ever see the Sphere stuff again.
