iIBM System/360 mainframe family. This gives you a better idea of what my job looked like. I loved working with these machines and its so hard to believe that you can hold a computer in your hand that does all what this did.
This is the 701. In 1953 the 701 was shipped by IBM. It was the first electronic computer created. During the computer's years of production, IBM sold the machines to aircraft companies, the government, and laboratories.
