Hey people.
I originally posted this on the redstone subforum rather than on the projects page but DinowCookies told me to post here so I guess I guess I might as well.

World download included in most recent update if you want to look at it. There will be a book describing how to use it. It's fairly straightforward but better safe than sorry. Also i forgot to delete something from the schematic above the calculator. Just ignore it, or mess around with it if you want (it's a hex divider).

So anyway here's an 8 bit 4 function calculator I
made. It can add, subtract, multiply, and divide 2 numbers from 0-255 (0
- 11111111 in binary).

Basic overview,
It has a BCD to Binary input system which then leads into each unit and
depending on what operation is selected, the input will be saved to that
unit and calculated. The output would go into a Binary to BCD decoder
into several binary to decimal decoder to display the answer. The inputs
also go int oa Binary to BCD and a Binary to a Decimal decoder to
display the inputs on the screen. (I know this will be confusing to
people who don't know much about binary logic, feel free to ask me for
some clarification. I might at some point also make a tutorial on different components of the calculator)
