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.

Well, the (IMHO very modest) price for a lifetime (!) membership of "The Friends of the Museum of HP Calculators" is the DVD set, containing all the information you were looking for. Yes, even HP manuals are sometimes not perfect, but if you find the same facts in more than one manual you can be pretty sure that's the truth - in those times, HP quality was more than just a word. And you've seen the confirmation for that right now: the tests proved what's stated in the respective manuals as I've mentioned in my earlier post.

Anyway, all you need to do is becoming a member and then roam all the museum premises free of further charge. I recommend that way.
