While you are there, pick up a copy of # 3969682, which relates to the SSM2040 and is presumably the source material for the various clones.
Any ideas why page two of the SSM2040 pdf is blank? Figures 2 and 3 are missing. The Freepatentsonline and googledocs link from George's website both have the same document, both with page two blank.
Thanks,
Tom
