Source code is located in _MicSim_ folder. All the components used for the Mic-1 architecture are Source code is located in `MicSim/` directory. All the components used for the Mic-1 architecture are located in `MicSim/components/` directory:
located in _MicSim/components_ folder: - `ijvm.py` Contains standard IJVM constant
- **ijvm.py** Contains standard IJVM constant - `microprogram.py` Contains IJVM implementation that use Mic-1 architecture
- **microprogram.py** Contains IJVM implementation that use Mic-1 architecture - `caretaker.py` Hold all the Mic-1 architecture components (registers, ram etc..)
- **caretaker.py** Hold all the Mic-1 architecture components (registers, ram etc..) - `ram.py` Contains a simple RAM implementation
- **ram.py** Contains a simple RAM implementation

Simply by editing **ram.txt**. Each line corresponding to a byte entry starting from address 0x0 to whatever to $+\infty$ . Each line can be an IJVM _opcode_ or a random byte. Here is an example of how to add two number: Simply by editing `ram.txt`. Each line corresponding to a byte entry starting from address 0x0 to whatever. Each line can be an **IJVM opcode** or a random **byte**. Here is an example of how to add two numbers:
