The IBM 5576-C01 Keyboard was a unique compact profile full-sized Model M offshoot featuring an integrated TrackPoint II pointing stick. It was designed for the IBM PS/55E, an all-in-one PC exclusively sold in Japan. Whilst most of IBM of Japan's infamous keyboards were produced by Alps Electric or Brother, this was one of the few (if not the only one) produced by IBM in the US for Japan and the only one to be buckling springs based but not use Brother buckling springs. Its buckling springs implementation is however slightly different to standard Model M specs. These also feature a unique rotating stand mounted on the back of the keyboard.
