Of course I checked the museum's HP25 page. The only reference to ENG mode I see is the sentence "Engineering display mode was also a first on this calculator". Where did you find further information and details, especially the n+3 rule in ENG mode?

Walter, I do not own an HP25 and I also don't know a free source for its manual. So how should I RTFM? But that's not the point. I asked for results from a "real" HP25 because manuals are not always clear and unambigous, sometimes the information they give is even plain wrong. That's why I asked for results from an actual calculator. Many thanks to everyone who provided this information.
