On February 16, 1984 — 31 years ago today — IBM introduced its first portable (“luggable”) computer — the IBM 5155 — designed to compete with the successful Compaq portable computer, which was the first compatible IBM PC clone. In its first year of sales, the Compaq portable had sold 53,000 units. IBM introduced the 5155 to take part in this big demand for portable computers.
The IBM 5155 (Model 68) included a built-in 9-inch monitor, amber composite display, and one 5¼-inch double sided diskette drive (with space for an optional second drive). The system board was the same as the IBM PC XT with 256K of memory, expandable to 512K using the memory expansion slot.
