year 1983

The IBM Personal Computer XT (IBM 5160), often shortened to the PC XT or simply XT, was IBM’s successor to the original IBM PC. It was released on March 8, 1983, and was one of the first computers to come 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 system was largely intended for business users.The XT originally came with 128 kB of memory, a 360 KB double-sided 5 1/4″ full-height floppy disk drive, and a 10 MB hard drive, a serial port, eight 8-bit ISA expansion slots, and Intel 8088 microprocessor (with a socket for an 8087 math co-processor).
