I know, that title is about as vague as saying "That is green." and point somewhere in a forest, but here's what seems to elude me. In Star Wars, specifically the OT, and I think only in TESB and ROTJ, there are times you see the black-jumpsuit crewmen fiddling with what looks to be a tablet of some kind. I've seen it once or twice, but now I can't seem to find it again. Can I get some help in finding this, or have I gone mad and it doesn't exist?
