IBM Personal Computer XT
The IBM PC XT (Personal Computer XT) was introduced by IBM in March 1983, as successor of the IBM PC. It came with IBM PC BASIC in ROM. In its day the terms "IBM XT" and "XT" were often used as class distinctions, so an "XT compatible" was used for a computer that had a full 640k or more of memory and a hard disk drive as standard while a "PC compatible" was used for computers with lower specifications, but that term is never used in today's parlance.
