When the IBM PC was introduced in 1981, it was originally designated as the IBM 5150, putting it in the "5100" series, though its architecture was unrelated to the IBM 5100's. [4] The 5100 was IBM's second transportable computer. Previously, a truck-based IBM 1401 was configured in 1960 for military use and referred to as a mobile computer. [5]
After IBM introduced the IBM PC, it was not until 1984 that IBM PC and clones became the dominant computers. [4] In 1983, Byte forecast that by 1990, IBM would command only 11% of business computer sales. Commodore was predicted to hold a slim lead in a highly competitive market, at 11.9%. [5] Around 1978, several 16-bit CPUs became available.
