If we had the ability (or the budget to present one) we have to award Casio in recognition to technological innovation. The PF-8000 is but one of many amazing gadgets churned out by this extraordinary company. This calculator was more of a computer and personal organizer (PDA in contemporary-speak) as it stored names and phone numbers, and could run basic programs! A significant achievement in its own rite, but we haven’t mentioned user input–it’s performed using a touch-sensitive keypad! That’s right, program your next hashing algorithm with the tip of your finger. The PF-8000 was one of many models in Casio’s Super Memory Computer line.
