I played around with PC keyboards a few years ago. I found two
problems running with different makes - firstly the clock rate can
differ significantly between keyboards, and secondly many keyboards
had automatic XT/AT mode detection. This worked in several different
ways, some of which confused my product - e.g. one keyboard would send
a code with a deliberate parity error, and if the host didn't request
a re-send it went into XT mode.
Although XTs are long dead, it's entirely possible that this
functionality may remain in some current keyboards if they are based
on old firmware.
