Editing IBM PS/55 Keyboards

The '''IBM 5576''' keyboards were a series of keyboards for IBM Japan's PS/55 line of computers which were produced from 1987 to 1995. They were made by a variety of manufacturers using a variety of switch types, and are PS/2 compatible. The designation was also given to some cost reduced rubber dome/sleeve keyboards that were used on PS/V Aptiva, the successors to the PS/55 line. While earlier members of the 5576 series were quite similar, later designs deviated such that it is hard to define common attributes for these keyboards.
