As a physicist working for the US Navy at a time well before the IBM peecee 
appeared, let alone Windows, we wanted to use the computers on Minuteman 
missiles that were being decommissioned. The idea was that everyone in the 
laboratory could have a machine on his desk as opposed to using a dumb terminal 
or flexowriter attached with an RS 232 pair to the big machine. Plenty of 
talent was available to handle the software.

What a great idea that was not to happen.

It appeared that the very special disks, that were needed for any kind of 
operation, once had targeting information on them that nobody knew how to erase 
with certitude. They got crushed along with the computers.
