You can run a fully functional, retro-style fantasy computer directly in your modern terminal. Mini Micro offers a sandboxed environment for programming and experimentation without the complexity of modern OS overhead. This system provides a pure, isolated space for coding, making it ideal for hobbyists who want to avoid the heavy configuration of modern development environments. By following this guide, you will learn how to download the binary, configure your display for high-DPI monitors, and execute your first BASIC program. By the end of this tutorial, you will have a working Mini Micro instance ready for creative scripting and software exploration.
Download and Extract the Binary
Before you begin, ensure you have an active internet connection and enough disk space to store a small archive.
Step 1: Locate the release files
Navigate to the official Mini Micro GitHub releases page.
This is where the developer hosts the latest versions of the software.
Step 2: Select your operating system version
Identify the file that matches your specific operating system.
Choose the Windows version if you are on a PC, or the macOS or Linux version if you are on a Unix-based system.
Step 3: Download the archive
Download the archive file to a dedicated folder on your computer.
I recommend creating a new folder named MiniMicro to keep your files organized.
Step 4: Extract the contents
Extract the contents of the downloaded archive into your new folder.
This process unpacks the executable file from the compressed folder.
Note: Mini Micro is a single-file application. You do not need to run an installation wizard or a setup program.
Step 5: Set executable permissions (macOS and Linux only)
If you are using macOS or Linux, you must ensure the file has permission to run.
Open your terminal and navigate to your MiniMicro folder. Run the following command:
chmod +x minimicro
This command marks the file as an executable program.
Verification
Check your folder. You should see the minimicro executable file sitting alongside any other extracted files.
If you see a permission error when trying to run the file later, repeat the chmod step.
Once the file is extracted and permissions are set, you are ready to launch the interface.
Launch the Emulator Interface
By the end of this section, you will have the Mini Micro environment running in your terminal and ready for commands.
Step 1: Open your terminal
Open your system's command line interface. Use Command Prompt or PowerShell on Windows, or Terminal on macOS and Linux.
Step 2: Navigate to the binary folder
Use the cd command to move into the directory where you extracted the files. For example, if you extracted them to your Downloads folder, run:
cd Downloads/minimicro-folder
Step 3: Execute the application
Run the executable file using the appropriate command for your operating system.
On Windows, type:
minimicro.exe
On macOS or Linux, type:
./minimicro
You should see the neo-retro virtual computer[2] startup screen. This screen displays the Mini Micro logo and the current version number.
Step 4: Verify the system state
Wait for the application to finish loading. You must see a READY prompt at the cursor.
This indicator means the command-line shell[1] is active and waiting for your input.
If you see a blank screen, check your terminal settings. Ensure your terminal supports UTF-8 encoding to render the logo correctly.
Step 5: Exit the application
To close the session, type the following command and press Enter:
QUIT
You have now successfully launched and closed the emulator interface.
Configure Keyboard and Display Settings
By the end of this section, you will have customized the visual and input settings to ensure the emulator is readable and responsive on your specific monitor.
Because Mini Micro mimics a physical terminal[2], the default settings may not match modern high-DPI displays. Adjusting these settings prevents text from appearing too small or blurry.
Step 1: Open the settings overlay
Launch the application as you did previously. Once the READY prompt appears, press the F1 key.
This opens the help and settings overlay, which contains all available configuration options.
Step 2: Adjust the font size
Locate the font scaling options within the overlay. Use the + key to increase the size or the - key to decrease it.
Continue adjusting until the text is clear and fits comfortably within your window resolution.
Step 3: Configure the keyboard layout
Navigate to the keyboard settings section. If you are using a non-US standard keyboard, select the layout that matches your physical hardware.
This ensures that special characters and commands map correctly to your keys.
Step 4: Save your preferences
Find the save command within the menu. Select it to ensure your changes persist across future sessions.
If you do not save, you will have to repeat these steps every time you launch the emulator.
Step 5: Verify the configuration
Close the application and restart it. Check the text clarity and ensure your keyboard inputs behave as expected.
You should see clear, legible text that is easy to read at your monitor's native resolution.
Note: If the text remains unreadable, check that your terminal emulator supports UTF-8 encoding, as this affects how characters render.
Write Your First BASIC Program
By the end of this process, you will have written, executed, and modified a simple script that runs in a continuous loop.
This environment acts as a command-line shell for writing programs[1]. You will use the standard input method to enter lines of code directly into the system.
Step 1: Enter the first line of code
Type the following command exactly as shown:
10 PRINT "HELLO WORLD"
Press Enter.
This line tells the computer to display the text inside the quotation marks.
Step 2: Create an infinite loop
Type the following command:
20 GOTO 10
Press Enter.
This line instructs the computer to jump back to line 10 immediately after finishing line 20. This creates a loop that repeats forever.
Step 3: Execute the program
Type the following command:
RUN
Press Enter.
You should see the text "HELLO WORLD" repeating rapidly down your terminal screen.
Step 4: Stop the running program
Press Ctrl+C on your keyboard.
This interrupts the loop. You should see the READY prompt reappear, indicating the system is waiting for new commands.
Step 5: View your stored code
Type the following command:
LIST
Press Enter.
You should see your two lines of code displayed in the terminal.
Step 6: Modify the program
Type the following command to change the text:
10 PRINT "YOUR NAME"
Replace YOUR NAME with your actual name. Press Enter.
Step 7: Verify the change
Type the following command:
RUN
Press Enter.
You should now see your name repeating on the screen instead of the previous text.
Note: If the text does not appear, ensure you included the quotation marks around your name. The system requires them to recognize the text as a string.
Explore Built-in Games and Utilities
You can interact with the system's pre-loaded software to see what the environment can do without writing any code. This allows you to test the hardware emulation and input responsiveness immediately.
Step 1: Access the game library
Type the following command at the READY prompt:
LOAD GAME
This command opens the internal library of pre-installed software.
Step 2: Launch a program
Choose a simple title from the list, such as SNAKE or T0R. Use the arrow keys to navigate the selection and press Enter to start.
Playing these titles helps you understand how the system handles real-time input. It is a great way to see the neo-retro virtual computer[2] in action.
Step 3: Control and exit
Use the arrow keys to move your character or navigate the game interface. To stop playing and return to the command line, press the ESC key. If the game does not respond to ESC, look for on-screen instructions provided by the program.
Note: If the controls feel unresponsive, check your keyboard settings. Some games may require specific keyboard configurations to map inputs correctly.
Step 4: Inspect all built-in files
To see a complete list of every program stored in the system, run this command:
CAT
This command lists all available built-in programs. It is useful for discovering utilities or hidden demos that you might have missed.
These built-in assets demonstrate the system's capabilities. While you have already learned how to write basic loops, these games show how the MiniScript programming language[1] can drive complex, interactive logic. By exploring these files, you can find inspiration for your own future projects.
You now have a fully functional Mini Micro environment running on your computer.
This setup provides a secure, isolated space for experimentation. Hobbyists and educators can use this system to teach programming basics without any risk to their primary operating system. Because the environment is self-contained, you can test experimental code or scripts without worrying about accidental changes to your main files.
To move beyond simple loops and built-in games, you must learn to manage your work across sessions. Use the SAVE and LOAD commands to persist your programs. Think of it this way: treat Mini Micro like a real, disk-based computer. By saving your scripts to your local drive, you can build a library of custom tools and games that survive every time you close the application.
Step 1: Verify your persistence workflow
Before you start complex projects, confirm you can retrieve your work.
- Write a simple script in the editor.
- Use the
SAVEcommand followed by a filename. - Close the Mini Micro application.
- Relaunch the application.
- Use the
LOADcommand with your filename.
You should see your previously written code appear in the editor.
Step 2: Expand your technical knowledge
As you become comfortable with the basic interface, you will need more complex instructions. The system relies on the MiniScript programming language[1] to handle logic. I recommend exploring the official documentation for advanced syntax. This will help you move from simple print statements to complex, interactive logic.
