One might also note that the PS/2 port is electrically compatible with the old AT keyboard that debuted in 1984, on a system with a 6MHz 8086.
Additional things that one might note:
- the AT keyboard debuted in 1984 as part of the IBM PC/AT system, which was based on the 80286, though some 8086/8088-based PC- and XT- compatibles got BIOS updates that allowed the AT keyboard to be used on them
- with the advent of USB, fewer and fewer desktop PCs over the past decade have been including PS/2 ports, with inclusion on laptops now approaching zero
