HP TSB internals - test-drb@ccmp.vtda.org

7 Aug 1999

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!

   reverse
engineering.

 I'll probably get to scanning a few parts of it in next week. 
But you said it was _hand written_?  That sounds rather counter-productive.

...not that I'm complaining about the fact that you have it, of course. I'd
...
 be fascinated to see it.  Someone else said correctly
that this kind of docu-
...
 mentation was rare.  It seems to me that's
especially true about HP, which
is a shame since their stuff's so well-designed.  I could be wrong about
that impression though.

Are you coming to the VCF?  Or if not, I wonder if there will be any 2100
hardware there?
