IBM PC keyboard

The keyboard for IBM Personal Computer, and compatible computers, is standardized. However, during the more than 30 years of PC architecture being frequently updated, many keyboard layout variations have been developed.

A well-known class of IBM PC keyboards is the Model M. Introduced in 1984 and manufactured by IBM, Lexmark, Maxi Switch and Unicomp, the vast majority of Model M keyboards feature a buckling spring key design and many have fully swappable keycaps.
