Hi, For quite a while now, I've been trying to get my hands on an old piece of IBM documentation for my collection before it is lost forever. So long, in fact, that I'm offering a reward of 500 USD to anyone that can find it for me. I've tried using my Google ninja skills, I've tried with IBM, I've tried libraries, and I've tried contacting a couple of patent authors that have used this as reference material. Perhaps you can do a better job than me. IBM Personal System/2 Mouse Technical Reference (S68X-2229-00, 2nd ed., Jun. 1989, IBM Corporation) If you are only able to find it at a library, see if you can borrow and scan it for me; that works just as well for me. Know that I already have the first edition of this document so I am not interested in it. Good luck! Cheers, Bogdan
