The IBM Personal Computer XT, often shortened to the IBM XT, PC XT, or simply XT, was IBM's successor to the original IBM PC. It was released as IBM product number 5160 on March 8, 1983, and came standard with a hard drive. It was based on essentially the same architecture as the original PC, with only incremental improvements; a new 16-bit bus architecture would follow in the AT. The XT was mainly intended as an enhanced machine for business use, and a corresponding 3270 PC featuring 3270 terminal emulation was released later in October 1983. XT stands for X-tended Technology.
