IBM 5110

The IBM 5110 is a portable computer introduced by IBM in January 1978. It was the successor to the IBM 5100 Portable Computer and a predecessor to the IBM Personal Computer. The 5110 was aimed at professionals and businesses, offering a self-contained computing solution that could be moved relatively easily.

Key features of the IBM 5110 included an integrated keyboard, a five-inch CRT display, a tape drive for program and data storage, and up to 64 KB of RAM. It supported both APL and BASIC programming languages, selectable via a switch on the front panel. It offered improvements over the 5100, including increased memory capacity and faster tape drive access.

The system's portability, while significant for its time, was limited by its size and weight. It was designed to be carried, but not easily transported for long distances. The 5110 was sold with a variety of software packages and peripherals, further enhancing its capabilities for specific business applications. The IBM 5110 represented an important step in the evolution of portable computing, bridging the gap between large mainframe systems and the emerging personal computer market.
