The IBM Personal Computer XT 5160 (or simply, PC/XT) was the successor to the ground-breaking IBM Personal Computer 5150 and was announced on 8 March 1983. Compared to the earlier model, the system featured a revised system board, increased RAM, and a 10MB Hard Disk.

A derivative, the 3270PC, featured hardware to provide 3270 terminal emulation.
