Amdahl 470 and 580 Computers
Amdahl Corporation was founded by Gene Amdahl in the early 1970s, and it later became a major competitor to IBM in the mainframe market. Its initial goals were to develop an IBM-compatible System/360 mainframe that would provide superior performance to the existing IBM machine at a lower cost. Amdahl’s first product was the Amdahl 470V/6, which was an IBM-compatible System/370 mainframe that could run IBM software. It was released in 1975 and was an alternative to a full IBM proprietary solution. Amdahl moved into large system multiprocessor design from the mid-1980s, and it introduced its 5890 model in 1985. Its superior performance allowed Amdahl to gain market share and increase its sales.
