Yup, it was fully known as IBM PS/2, for "Personal System 2". IBM wasn't happy about how the original PC system got cloned to hell and back, so they designed a more proprietary and patentable system. Suffice to say it was a massive failure, what with it being incompatible with basically all of third party hardware. But the keyboard and mouse ports were widely regarded as a good idea! (and probably not as patentable)
IBM really loves their slashes huh.
