I know of come very large companies that still run some DOS and win95 computers due to legacy issues, in fact they have store cupboards of old PC's to use when the ones running the OS breaks.

That is just laughable though. It makes no sense to carry on doing this. They would probably save enough in energy and storage costs alone to make excuse for them to get with the times. Storage is very rarely in abudance in organizations. What a management headache that must be. Then again, they probably don't realise what they are missing, hence problem.
It seems very short sighted to me that things are still running DOS and Windows 95 because nobody has the balls to upgrade the system. Honestly, it's just a joke.
Perhaps the problem was their bespoke software was designed and coded by idiots meaning as soon as any sort of OS upgrade came out, it was so difficult to get the software to work on the new system, and/or issues to migrate from the system - well as said previously, they should have thought of that when they got people to develop software, and it's not really an excuse, because eventually it will need to be done.
