[[File:IBM PC XT 5160.JPG|thumb|IBM PC/XT 5160 dual floppy drives with 5153 Color Monitor]]
IBM made several submodels of the XT.
Line 119 ⟶ 118:
{{anchor|End of life}}Both the original XT and the XT/286 was discontinued in the spring of 1987 when the [[IBM PS/2|IBM Personal System/2]] (PS/2) line was announced. The 8086-powered [[IBM PS/2 Model 30]] served as the direct replacement for the XT in that PS/2 line. Unlike higher-end entries in the PS/2 line, which feature the [[Micro Channel architecture|Micro Channel]] expansion bus, the Model 30 contains 8-bit ISA bus slots, exactly like the XT.
