it's the USB port in my G19 keyboard
That bites - I hope you can fix it, because if you paid anywhere near what I am seeing them advertised for...
You coulda bought two Unicomp "Model M" buckling spring keyboards (they double as weapons) for that price; and it would be likely you would pass them on to your grandchildren.
Nothing beats an original Model M, though - except maybe the original XT keyboard (solid aluminum shell, weighs a ton, and buckling spring - who couldn't like that?).
/I love my Model M and Unicomp keyboards...!
