Today, after reading about some contest entries to a contest to produce an awful four-function calculator.
Inspired, I decided to make my own.
Here it is, the Bitulator.
Spoiler for Code:

Beware, use it too many times without exiting the program, and the stack can start corrupting stuff. When it starts displaying noncharacters instead of numbers, that's a good sign it's about time to quit.
The source is also attached, in case you like your sources in 8xp form

According to geekboy, it'll take about 40 subroutine calls for the stack to start overwriting stuff, meaning that you have about nine or ten calculations to use before it starts overwriting stuff. I think.

I'm not worried about SOPA creating censorship, that will not stand for long. I'm worried that they'll succeed in stopping piracy!

And actually the fact that the CPU is virtually Identical lends to faster speeds than you'd expect. TI-Boy is another example of a fairly speedy z80 emu for the 84+.
