Macintosh Pi

Abstract

1. Introduction

MacintoshPi is a small project that allows running full-screen versions of Apple's Mac OS 7, Mac OS 8 and Mac OS 9 with sound, active Internet connection and modem emulation under Raspberry Pi. All this without the X.org manager, only a multimedia SDL2 library and from the CLI / Raspberry Pi OS (Legacy). This lets emulators use full power of Raspberry Pi, making them more stable and useful in combination with additional retro-software.

A much longer version of the clip can be found here.

Apple-1, Apple ], Altair and IMSAI emulators moved to the new [DinosPi project.

2. Objective

MacintoshPi is a project that allows running full-screen versions of Apple's Mac OS 7, Mac OS 8 and Mac OS 9 with sound, active online connection and modem emulation under Raspberry Pi.

This project demonstrates how Shell, Raspberry Pi can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

• Macintosh 68K emulator Basilisk II supporting Mac OS 7 (System 7.5.5) and Mac OS 8.
• PowerPC emulator SheepShaver supporting Mac OS 9.
• A development library SDL2 designed to provide low level access to audio, keyboard, mouse, joystick, and graphics hardware.
• Commodore 64/128/PET emulator VICE.
• A consistent MacintoshPi Launcher that runs all of those systems at different resolutions (after reboot), in different configurations, with autostart support and with various startup chimes.
• SyncTERM - an application for connecting with BBSs from the Raspberry Pi OS, compiled in combination with the SDL library.
• Information how to run Raspberry Pi OS in dual-boot with BMC64, the fastest Commodore emulator for Raspberry Pi (bare metal/low latency emulator).

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Linux / macOS terminal or WSL on Windows
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/jaromaz/MacintoshPi.git
cd MacintoshPi

git clone https://github.com/jaromaz/MacintoshPi
cd MacintoshPi
./build_all.sh
# That's it - now you can run, for example, Mac OS 9:
mac os9

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a mobile dashboard using Blynk or Firebase
• Store readings in a cloud database for history charts
• Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
