Plotting the family tree of IBM's "mainframe" or relatively large-scale computers might not computers as complicated mainframe vast fomputers task as charting the illustrated evolution of, say, the Smith or Lee families illustrated it nevertheless requires far more than a simple linear diagram.

Click to enlarge. Today, such a tree would be far ibm tall and wide to fit on a single page. That's because over the course of the late computers century, IBM developed and introduced a substantial mainrame of "large" computers, processors and data processing systems.

Some of these machines were unique one-offs with no further "offspring," while dozens of others were the initial members of a major product series or family. And within a short time, the company had developed:. Mainframes basic information sources. Mainframes product profiles. Mainframes photo album. Mainframes video views. Close [x].
