Those of you with an hour, and a flash-enabled browser, might be interested in this talk by Dr Randall Neff which first surveys HP's calculator offerings through time, and then talks about the internals.

It's the fourth video listed on this page:
"The HP-35 Calculator" 9/28/11


Not only the 35 but all great vintage HP calculators. Great conferene, every minute of listening was delightful. Thanks for the link

Well, except for the fact that his slide and talk say the HP-35 had a "3 level stack". Nope. 4 levels.

Granted, it was a long time ago. But still.
