The IBM 700/7000 series is a series of large-scale computer systems that were made by IBM through the 1950s and early 1960s. The series includes several different, incompatible processor architectures.

Some 25 times to 50 times faster than its predecessors, the 701 inaugurated IBM’s 700 series with rapid advancements in computing power, memory capacity and economy of size, making history as the company’s first electronic computer.

The IBM ThinkPad 700 (also named model 700 PS/2) is the first notebook computer for the ThinkPad brand that was released by IBM on October 5, 1992. Another series was released alongside it, the ThinkPad 300 series. The 300 series was meant to be a cheaper, lower performance model line over the 700.

The IBM 701 Electronic Data Processing Machine, known as the Defense Calculator while in development, was IBM’s first commercial scientific computer and its first series production mainframe computer, which was announced to the public on May 21, 1952. [1]

These new ThinkPad notebook computers were an immediate hit, and collected more than 300 awards for quality and design. All three models were released at about the same time, ranging from the cost-effective model 300 to the top-of-the-line model 700C (the C is for "color").

The IBM 700/7000 series is a series of large-scale (mainframe) computer systems that were made by IBM through the 1950s and early 1960s. The series includes several different, incompatible processor architectures.

This volume describes several different models of IBM computer systems, characterized by different data representations and instruction sets that strongly influenced computer system architecture in the 1950s and early 1960s.

The IBM 700 series were binary (as opposed to decimal) vacuum-tube logic computers with 36-bit words. The 704 was a 701 with core (rather than CRT) memory, floating-point arithmetic, and a bunch of new instructions; 123 of them were sold from 1955 to 1960.

The IBM 700 Series IBM's first generation mainframe computers, in two lines, scientific and commercial. The scientific line consisting of the 701, 704 and 709 were 36-bit binary machines with an accumulator architecture.

From 1952 into the late 1960s, IBM manufactured and marketed several large computer models, known as the IBM 700/7000 series. The first-generation 700s were based on vacuum tubes, while the later, second-generation 7000s used transistors. These machines established IBM's dominance in electronic data processing ("EDP"). IBM had two model ...
