I ran Internet banking for a small bank in the early 2000's. We had our IBM mainframe right next to a bunch of HP/UX servers. It was just massive and had a nice red button which they warned all of us to stay clear from. I recall that was around the time running Linux on the mainframe was becoming a thing and we tried to run Websphere and our J2EE app on it. It was not successful (too slow) and we kept running on HP/UX.
