There does come a point when you have to take a computer off the Internet to use an old system, just to be sure you don't pick up a piece of malware, virus, etc. that the old system isn't protected from.
I still have an image of a WinXP drive, and another image with Win7, but I won't leave my network active while running them. The same is true for drives with OS X versions 10.6.8, and 10.10.x.
I have a friend who uses a computer running DOS to generate CAD drill files for his business. Why spend money on new software and a new computer and spend time learning it all to get exactly the same output files? If you have a business and a tool that works, you like to keep it going as long as possible to maximize profits.
