It seems that one company is missing.

I did have the TI SR10. I think it was my first calculator.

It isn't only HP which is missing from the list. Others from my limited collection include Checkmate, Cybernet, Korvette, Miida, Monroe, Montgomerry Ward, Royal, Soundesign, Teal and Unicom.
As to old adding machines I prefer some of the genuine antiques where my favorites include the rotary Addometers (made by a typewriter company and built like a truck) and the Magic-Brain pocket size push down adders.

I am slowly revamping the images and descriptions - and have another 100+ calculators to put on - so keep looking!
Odds are the 100+ includes many HP's. Saving the best for last?
