The IBM 4860 PCjr was IBM's first attempt to produce a low cost personal computer aimed at the home market. It used a low cost keyboard designed to be more suitable to the home market than the Model F keyboards of their professional computers. The PCjr is widely considered to be one of the worst keyboards ever designed, and considered to be one of the main reasons why the PCjr was a commercial disaster.
