The 8B01 is a calculator that can add two numbers to show an answer in binary (Ones and Zeros).

This calculator is better than the last one since it can now add bigger number to show an answer up to 255 instead of the old one supporting only to 15, which is a significant improvement. If you want a translation of numbers in binary, there will be a wall of signs in game translating that for you. Keep in mind, that 1 is the same as a flipped lever or lit redstone lamp and 0 is the same as an unflipped lever or unlit redstone lamp. Each 1 or 0 is referred as a bit, every time you add a bit the maximum number doubles and then it minuses by one, so that's why the maximum number is 255 and not 256 this is because one of the combinations should be set as zero which is "00000000".

I haven't 100% planned the next calculator yet, but I think I'll try add subtraction of number and bit count might double to 16 bits if necessary, so stay tuned for next calculator.

I was going to add a 3 digit 7 segment display but I couldn't due to lack of knowledge of converting binary to 3 digit 7 segment display, with it I tried adding decimal mode, which needed the display to work. So, I reverted back to binary blinking light redstone lamps that I used earlier in the 4-bit calculator but with more lamps to accommodate for the 8 bit architecture it has.

Anyways, Enjoy! :)
