There is NO PROOF that any IBM is older than 20 years.
Actually, tjhere';s no proof that the world is more than, say, 10 second
old. It might have been created with all of us on it, with all the
memories we have, and so on. You can't _prove_ that's not the case :-)
But if oyu acept the more normal view, then I've had na IBM computer for
more than 20 years.
