More on this type of keyboard...
The IBM 5576-C01 Keyboard was a unique compact-profile full-sized Model M offshoot featuring an integrated TrackPoint II pointing stick. It was specifically designed for use with the IBM PS/55E, an all-in-one PC exclusively sold in Japan. The 5576-C01 has the unique distinction of being amongst the relatively few Japanese IBM keyboards that weren't made by ALPS Electric or Brother and the only buckling springs Japanese keyboard that doesn't use Brother buckling springs. These however use modified buckling springs that are said to feel slightly different to other Model Ms. The most unique feature with these is the large rotating vertical stand that allows you to park the keyboards upwards on its back wall. They could also come in proprietary combined signal PS/2-like cable or a more standard Y-split keyboard and mouse PS/2 cable. It is a candidate for the last IBM-sanctioned buckling springs keyboard design and its moulds were later used to produce the Unicomp EnduraPro/SpaceSaver family.
