The IBM 5100 represented a breakthrough in portable professional computing when launched in September 1975, compressing mainframe-level programming capabilities into a 55-pound "luggable" computer priced between $8,975 and $19,975 (equivalent to $52,000-$117,000 today). This revolutionary system bridged the gap between room-sized mainframes and the personal computer revolution, serving specialized markets in government, research, and business sectors through its unique combination of APL and BASIC programming languages previously available only on much larger systems. Despite limited commercial success with relatively small production numbers before its discontinuation in March 1982, the 5100 established crucial technical precedents for portable computing and demonstrated IBM's early recognition of single-user computing potential. The system's legacy extends beyond
