this is a simple (but messy) computer inspired by the computer in the game Turing complete,

it currently runs a multiplication program

to run:

1: make sure program is set to 0

2: click restart button to set instruction counter to 0 and reset the registers

2: set Run to 1

to program:

1. set program to 1 and run to 0

2. click resetprogram to reset the EEPROM and the instruction counter

3. enter the instruction

4. click the insert button to submit the instruction.

Repeat step 3&4 for all the instructions

(or just load in to the eeprom directly)

the instructions work as following:

opcode  argument 1  argument 2

 01          010              110

there are the following opcodes

00 immediate: loads the value into register 0

01 copy: copies the value from the register specified in argument 1 to the register specified in argument 2

10 Calculate: takes the values in registers 1 and 2, executes the instruction specified in argument 2(see ALU instructions), and returns the outcome into register 3

11 compare: compares the value in register 3 based on argument 2(see Compare instructions), if true jump to instruction in specified in register 0

ALU instructions

0 and

1 or

2 nand

3 nor

4 add

5 sub

(6&7 are currently unspecified, i plan on making these shift left and right)

Compare instructions

0: never

1: != 0 

2: < 0

3:<= 0

4: always

5: ==0

6: > 0

7: >= 0

Plans:

i'd like to add shift left and right into the ALU

i plan on making more intuitive controls, inputs and outputs

i'd also like to add memory to read from or write to.

finaly i might make the other structure from the game but that'll be another circuit :-p

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
