MS-DOS runs the US Army's food service management system

When I worked at Burger King a few years back, they used something very similar for stock control and daily takings.

I don&#x27;t have any problem with them using ms-dos because maybe its a good system, and there is no need to change it. But the pic with the floppy disks...<p>Where do they buy floppies? drives? motherboards for those drives?
