I'm frustrated- I just got off the phone with the USPTO, trying to find another patent wrapper, but it seems they misplaced it. It's for patent 4165159, and it looks like the wrapper includes the Rockwell PPS-4/1 Hardware Manual and the Rockwell PPS-4/1 Microprocessor Programming Manual. But the file wrapper isn't in their system, so I can't order it. The only possibility that they offered is that maybe it was incorporated into another patent, but I can't find any that reference it, so I'm stuck.
