For some reason I didn't scan this one at as high res as usual, though it's still quite usable and printable. A lot of the basic info applies to the later 45S head, but this has all the lowdown on the 7 segment displays and such that are unique to this model. (I'd rescan it at a higher res but I think it went away with the last computerized head I sold a few years ago. If I run across it again I'll rescan it and put it at the same URL for future downloaders to enjoy.)
