How to use

Run computer_interface.py. This currently serves as a very basic "operating system" for the computer.

To-do list

• Input/processor interrupts
• Audio
• More peripherals
• Processor clock cycle

What is NOT simulated

• Hardware circuitry
  • CPU voltages
  • Display scanlines
  • etc.
