Now it's time to do something useful with it like testing the Collatz conjecture with 27 using the (12C) 3n + 1 conjecture program from the Software Library.

PS: Don't keep your calculators in the drawers.

That looks interesting. You guys are way smarter than I am.

Today, I have been perusing RPL in my 48SX manual. I haven't written a RPL program in years and years. I've been thinking about writing a program that simulates a (very) simple Turing machine using the calculator display matrix rather than a tape.
Here is the pseudo code in my noggin:

repeat until any key
goto a random (x,y) location in the display
test if the pixel (x,y) is set or clear
if set, clear (x,y) and move left
else, set and move right
end

Simple program (I think). It would be interesting to add more rules and see what happens.

BTW, I keep most of my calculators in a cabinet. My 41CX and 48SX are nearby.
