However, there was a transition period where some keyboard controllers supported both XT and AT (PS/2) keyboards (through a switch, jumper, or auto-sense.) Also, some keyboards were made to work on both types of systems (again, through the use of a switch or auto-sensing.) If you have owned such a PC or keyboard, do not let it fool you--XT keyboards are NOT compatible with modern computers.
