In the early 1970s, HP bought up ALL the RPN-type patents from the old office-machine companies. This is why my baby, the National Semiconductor 7100 calculator, was algebraic and not RPN when it was under development in 1976/1977. This is also the major reason why nobody else in the entire world has ever dared to infringe HP's RPN patents now that they have bought them all. I just wonder if Aurora is named for the (rumored) Aurora space-plane, which has supposedly replaced the U-2, and the SR-71, and which is believed by many to fly faster than Mach 8. Mach 8 may well be the speed required to outrun Hewlett-Packard's herd of lawyers.

Hello Mr Chumbley. "...my baby, the National Semiconductor 7100 calculator..." !? Dare I ask you were in some way involved in the design of this one ? I'd be *VERY* (major understatement) interested in any information regarding this machine. Was there any prototype built ? Blueprints ? Thanks.

Quote: d) 2003 in New Port Beach honoring Joseph Horn. Even his “boss” was at the Saturday dinner. Jim Chumbly (National Semiconductor NS-7100 developer) also attended and we could remember the “old days.” I consulted on that project and it helped to inspire the PPC ROM.
I have limited info and will share ALL I have but the in-depth is with others - maybe the time is now to tell more, tell all - this user community certainly has the interest. Beyond what I've already emailed & referenced, I only have snippets from second hand sources.
BEST!
