On March 8, 1983, IBM released the Personal Computer XT, short for eXtended Technology, or PC/XT, or just XT. It came equipped with a 10 megabyte MFM Full-Height Hard Disk Drive with 306 Cylinders, 4 Heads, and 17 512-byte Sectors, was expandable to 640k of RAM on the Motherboard, and came with MS-DOS v2.1, which supported directories and subdirectories. It had one or two half-height 5 1/4 inch floppy drives, and was later available with a 20 megabyte Half-Height Hard Disk Drive with 615 Cylinders, the Seagate ST-225, interleaved at 3:1. It carried the nameplate 'IBM Personal Computer XT'.`` The expansion bus also contained eight slots instead of the original five. This gave users greater flexibility in the addition of peripherals to their machines. Because this machine was so popular, many manufacturers began copying IBM's design. These copies were referred to as 'clones.'

Since the introduction of the XT, there has been an explosion in the PC industry. This was largely made possible by the open architecture of the IBM PC and XT. Many 286,386, and 486 computers have been built with the same slot-width as the IBM XT, resulting in the term ISA, or Industry Standard Architecture.
