Basic 8-bit Computer with logic gates

Hurray, I made it in a the update video. I guess I should update it with faster componets and make it much better.

Working computer made with the new logic gates only cost ($1,000,000 ingame money to make)
It has:
- 7 bytes of RAM
- 7 functions for the CPU
- 15 bytes of ROM in 10 lines
- Currently programmed with the fibonacci sequence

To run it there are two switches in the center. The top one starts it and the bottom one stops the clock.

The ROM is where the program is stored. It is on the left side and is on the sand area
The RAM is where the data is stored. It is in the bottom left mosiac tiles.
The CPU is what does the the computing. It is in the top left in the grass.
The display is on the top right and uses servos to display the output. The value of each bit is on top it and is easiest to see in utilities mode.

How to program it:
The ROM stores 3 bits for each system
from left to right
first 3 are CPU codes,
next 3 are read from RAM for the first input,
next 3 are read from RAM for the second input,
The final 3 are for the location in RAM to store the data in.

CPU codes:
100 add
010 subtract
110 OR
001 NOR
101 AND
011 NAND
111 XOR

Registers are just binary 100 to 111

To put numbers into the RAM prior to running the program use the 8 switches below it to select numbers. The least significant bit is on the left. To place it in a register use the 3 switches on the right.
