Re: How does this software work??

From: <thomas@inorbit.com>
Can't say anything about that case; but around '71-'72, we upgraded a 2311
disk subsystem for a 1401 from 2.5MB to 5MB (IIRC). The CE removed a
stop-screw that had prevented the disk arm from fully traversing the
platters. Voila! Doubled capacity! If a customer did that without purchasing
the upgrade, I suspect IBM's recourse would be under voided warranty, etc.

==> that could be defended because it WAS a mechanical change to the system
that concievably might have some mechanical effect...
