Legacy systems a couple of months ago I was invited to a 40th birthday celebration for the IBM System/3 60 mainframe at the Computer History Museum in Silicon Valley. I can't say I was thrilled at the prospect, but I came away inspired. Launch team members described the incredible risk and resources ($5 billion in early 1960s' dollars) that went into the project. And of course, they were puffed with pride that the 360 has lasted so long. What's behind the staying power? Part of the answer probably lies in the 360's OS-which Fred Brooks, Jr., who led the development of the 360, calls "the first industrial-strength, 24/7 operating system." The ability to assume a computer would be up rather than down cemented "IBM mainframe" and "reliability" in people's heads.
