Andre. All four registers, x,y, z and t are identical, and reside in a single LIFO stack:
T Z Y X "X" is the register that is visible. The upper ones are above it, take a tiny bit of getting used to, and then unleash their power. One enters data from the keyboard into "x". "Enter" simply says: terminate data entry, and move the data in "x" to "y", "y" to "z" and "z" to "t" (t is lost). Any operator, like "+" says: add y to x, leave the answer in x; move "z" to "y", move "t" to "z" and leave a copy of "t" in "t". There is a "switch x and y" button, and a "rollDown" button, that shifts data downward, one register to another, and passes "x" back up to "t". That's it. That's all one needs.
