Using the keyboard, type in two numbers that add up to 0 through 9. Then hit the clock buttons (if you accidentally hit the reset button, it is okay. Just retype it). Then on the tty, hit the clock button. The numbers should be added!

About the Combinox R1:

This is the third 16-bit CPU I have made. Its new name was inspired by the new combinational code. It is also my first computer to feature a graphics and base ten display. As a result of its brand new architecture, code, and clock it is much faster than my previous CPUs. 


Directions for use:

Choose the desired EEPROM program and insert it into the slot. First press the "RESET" button. Now press the "ON" button and enjoy your program.


Descriptions of programs:

blank: A blank EEPROM to be coded.

count up forever: Counts up by one until it reaches 65,535 then loops back to 0.

2+2: adds 2+2 and displays the output to the number display

transfer from keyboard to display: Displays the ascii value of whatever key is being entered on the keyboard.

random noise: Displays random noise on the screen.

Fibonacci: calculates the Fibonacci sequence

Sequential Multiplication

Sequential Multiplication

This is an 8-bit sequential multiplier with an 8-bit output. It works by adding A to itself B number of times using an accumulator to keep track of what the value should be. Once the number of times A was added to itself is equal to B then it signals to the output and updates the data.
