You are very welcome! In the meantime you can press Control + Reset to enter BASIC which would allow you to write & run software in BASIC. BASIC does not have access to the disk drive. It is meant as a lightweight way to use the Apple. BASIC can however access the cassette interface for saving and loading software to a cassette tape.

If you have any questions regarding the Apple II then feel free to reach back out to us! I personally find great joy in using an Apple II. I still have my childhood Apple //e and lately I have completely upgraded it with a solid state disk, mouse, internet, 16-bit sound, more RAM, faster CPU, etc.. There is a project currently in development that took Apple’s ProDOS operating system source code for the Apple II and they are releasing updates which bring new features to the Apple II. With a proper RAM upgrade your Apple II+ would be able to run the more modern ProDOS operating system.
