I'll see your dual screen and raise you a Casio desktop calculator.

    This calculator looks like it comes with a hefty manual and has a following as devoted as vim users

    These are pretty simple calculators, those switches on top just change how the printing happens. You can set them to print with leading decimals (eg. adding a .00 to monetary values) and alignment to make reading easier. Otherwise it's just a pretty standard calculator. Great machines, you still see them used for audits as a final hand-calculation stapled to the top of the paperwork.

    This was the machine to count down registers at the end of every retail shift. Great little things. Training someone new on it was always a process though. A lot of people struggled with the concept of entering the sign/operation after the number.

    Example 10+2-5 = 7 is entered into the machine as 10 [+] 2 [+] 5 [-] [* or T]. Of course most people treated it like a regular calculator and hit 10 [+] 2 [-] 5 and then scratched their heads to find the equals.
