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, owing to its uncomfortable "chiclet" keys, non-standard layout (it was one of the first, if not the first, PC keyboards to use a Fn shift), unreliable IR link, and hardware limitations in the PCjr itself that prevented PC-style type-ahead from working properly. It's considered to be one of the main reasons why the PCjr was a commercial disaster.
A later "enhanced" version switched to more standard shaped keys. The internals of both versions seem to be the same, and the layouts are also the same.
