Just found this while cleaning some of my old boxes of stuff:
The poor thing is not working anymore but it made me remember my old days of late 70's as a proud owner of a 'calculator' in my college days.
This Casio fx31 had a green LED display and abilities of so called 'scientific' calculations. I do remember the group of curious girls giggling and gathering to see the calculator and the jealous frown from other boys of the class.
Good old days!
