Dude, TI-85's are for dorks. All the cool kids had the HP 28S with the RPN (Reverse Polish Notation) calculation method.

Ha, I've got you both beat. I was THE coolest kid, because I was the ONLY one with a calculator! I won the science fair in 11th grade (design of wood trusses - OK, I got a little help from my engineering professor father ), and the prize was a TI-58! What a sweet prize. That was when they still had state slide rule competitions.
