HP TSB internals

It is both hand written and printed. A large chunk of it is printed, but
obviously not for public publication (ie. internal use only). Many of the
printed sections are supplemented with hand written and diagrammed stuff.
However, most (but not all) of the hand written stuff is incredibly neat (a
ruler was used to draw the figures, etc.). Most of the hand written stuff
looked like it was being prepped for overheads.

So - than answer is both!
