 I get irritated when I search for HP9100 (meaning the first desktop 
scientific calculator thing) and get hits for some modern-ish
printer/scanner. Admittedly that is a 9100C (the calculators were
9100A and 9100B), but...

I seem to remember that there are at least 5 different HP10 calculators : 

HP9810 (which was called the 'Model 10 Calculator')
HP10 (or HP10A) : A simple handheld adding machine with printer
HP10C : The simplest of the 'Voyager' series. Scientific, programable
HP10B : A simple financial machine
HP10B-II : An upgraded HP10B
