[comp.sys.ibm.pc.hardware] XT and PC keyboard compatibility

Fellow Netters:

I have seen a couple of articles lately about keyboard compatibility 
between XTs and ATs.  Probably no one is interested, but I could not
get an XT keyboard to work with an original IBM PC (ca 1982).  Can 
anyone offer a plausible explanation?

The keyboard works great on an XT, but on the PC it sometimes sends
the correct letter, sometimes the wrong letter, and sometimes pressing
a key will trigger a stream of meaninless characters (kind of like me
writing my dissertation!).  The PC works fine with its original IBM 
keyboard.  I have the XT/AT switch on the keyboard set correctly.  And
I didn't plug it into the cassette port, either!

Thanks,

Dev Palmer
