Hello Peter,
Your image of the HP-45 RAM chip is most impressive, almost as impressive as your plan to reverse engineer the HP-35. Good luck with the project! You are probably aware that SwissMicros, a small manufacturer of RPN calculators based in Zurich, sell products which I presume involved reverse engineering a handful of HP calculator models, but not the HP-35. These are actual calculators, not simulators, and, to judge from my DM42 (a clone of the HP-42s which runs Thomas Okken's Free42), very well made. Their website is https://www.swissmicros.com. I assume that the current Hewlett-Packard company has absolutely no interest in what is surely a small niche business, and has left the field to this sort of small entrepreneurs.
Best wishes,
Rafael
