Courtesy of Eric Rechlin of hpcalc.org, now you can watch a fat ugly guy who says "um" far too often, at HHC 2025 talking about and demonstrating the forthcoming Nonpareil II microcode-level simulation of various HP RPN calculators (currently HP-15C and HP-16C):

The audience really liked that the graphics is fully scalable, rather than only having integer multiple scaling of a bitmap, in the original Nonpareil.
At HHC 2025, I learned of the existence of another HP-95C in private hands, which makes four that I know of.
The HP-95C was a desktop scientific programmable printing calculator, with continuous (CMOS) memory but no card reader. It would have been introduced in 1976, positioned between the HP-91 desktop non-programmable printing scientific, and the HP-97 desktop programmable printing scientific with magnetic card reader.
