UK 1998

🇺🇸 Step back in time to 1986 and witness the dawn of a revolutionary device—the IBM PC Convertible. As one of the earliest portable computers, the PC Convertible marked a significant milestone in the evolution of American personal computing, offering newfound mobility and versatility to professionals and enthusiasts alike.

💻 The IBM PC Convertible represented IBM's inaugural foray into creating a portable version of its iconic PC line. It was the first laptop-style computer following the luggable IBM Portable, and notably introduced the 3½-inch floppy disk format to the IBM product line. Featuring a clamshell design this groundbreaking device set the stage for future generations of laptops. Its compact form factor and relatively lightweight made it a practical choice for on-the-go computing—a novel concept at the time.

⌨️ Unlike earlier portable computers that required external keyboards, the PC Convertible boasted a built-in keyboard, enhancing its usability and convenience.

👉 The PC Convertible came in three models: PC Convertible, PC Convertible Model 2, and Model 3. The latter two were released in October 1987 and are primarily distinguished by their LCD panels. The original Convertible used a non-backlit panel, which was considered difficult to read. The Model 2 lacked a backlight as well but upgraded to an improved supertwist panel, while the Model 3 included a backlight.

🖥️ Equipped with an innovative flip-up monochrome, CGA-compatible LCD screen, the PC Convertible offered a crisp display for viewing documents and running applications—a revolutionary feature for its time.

💾 Powered by an Intel 80C88 CPU, the PC Convertible came with built-in storage options, including 256 KB of RAM (expandable to 640 KB) and dual 720 KB 3.5-inch floppy drives, enabling users to store and access data with ease. It also featured serial and parallel ports for connecting peripherals.

🔋 Despite its modest battery life by today's standards, the PC Convertible offered respectable uptime, allowing users to work on the go without being tethered to a power source. Weighing just over 12 pounds and featuring a built-in carrying handle, the PC Convertible's battery was rated for 10 hours.

🌟 The IBM PC Convertible was succeeded in 1991 by the PS/2 L40 SX, and in Japan by the IBM Personal System/55note, the predecessor to the ThinkPad. The IBM PC Convertible left an indelible mark on the history of computing, paving the way for the modern laptops we use today. Its innovative design and practical features demonstrated the potential of portable computing, inspiring subsequent advancements in mobile technology.
