The IBM XT was an extended version of the IBM PC. It provided extra slots, while removing the adapter for the tape drive. The IBM XT was also sold with a hard disk drive, along with a floppy drive, or as a dual floppy drive system. Since the 8088 CPU could address 1MB of ram, the memory map was split in a 640k for OS & programs, and 384k for hardware buffers and ROMs.
The IBM XT was later replaced by the IBM AT.
