Macintosh Portable

Released in 1989, the Macintosh Portable was Apple’s first attempt at a truly portable computer. Though heavy by today’s standards, it offered a full-sized keyboard and trackball, with later models featuring a backlit LCD screen for better visibility. This model provided a desktop-like experience on the go, making it an ambitious step toward mobile computing. Its built-in battery and unique sleep mode preserved battery life while maintaining data integrity, laying the groundwork for future laptops. This particular model is even more interesting, featuring Tim Cook’s engraved signature, making it a unique piece of Apple’s history. Despite its brief production run, the Macintosh Portable remains a significant milestone in Apple’s evolution
