* All the original green engineering papers are signed Chung Tung - so I presume this was his notebook.

Indeed, Chung Tung was one of 3 authors of the main HP-35 Article. His 'Bio' at the end of the article says:

Chung C. Tung
Chung Tung received his BS degree in electrical
engineering from National Taiwan University in 1961, and
his MSEE degree from the University of California at
Berkeley in 1965. Late in 1965 he joined HP Laboratories.
He was involved in the design of the 91 OOA Calculator and
was responsible for the design and development of two
of the MOS/LSI circuits in the HP-35 Pocket Calculator:
the control and timing chip and the read-only-memory
chips. Now working for his PhD at Stanford University,
Chung still manages to find time now and then to relax with
swimming or table tennis.

Knowing this somehow makes this find even more special!!
