Re: SCADA systems running windows
"About 3/4 years ago my boss went to a very high profile company that make helicopter parts, they still have a CNC machine running Windows 3.1.... it would be took expensive to replace. It was completely off the network."
Not a high profile company, but a 3-4 years ago I did some work for a company still using paper tape to programme one of their CNC machines. A couple of others had their programmes uploaded by RS232C from a PC in the office.
