The HP calculator was the darling in my engineering college, but I confess that I never liked it very much, just had the "enter" key and did not have the "="... Major fault ...

Nice photo by the way...
The use of RPN ( Reverse Polish Notation -- No equal)is something that took awhile to get used to but I am confused by calculator that have an equal button after using HP for 35 years
