Re: Oldest running MAIN PC? I have two pieces of medical equipment that I still use. One is a 486 running Win 3.1 and the other is a modified laptop that runs NT 4.0.
Why not upgrade? They work fine for the purpose they were designed for and upgrading would cost far in excess of hardware and software: it includes extensive testing and documentation that would need to be sent to the FDA for approval. In essence it would have to be done on thousands of machines and would cost millions of dollars and then you would have no real improvement in functionality.
