Let's delve into this fascinating journey.

The IBM 700/7000 series represents a pivotal era in computing, spanning the 1950s and 1960s, marking IBM's transition from electromechanical computers to fully electronic systems. These mainframes were among the first to use vacuum tubes and later transistorized circuits, showcasing significant advancements in computing speed, reliability, and capacity.

The IBM 701, introduced in 1952, was the first of the IBM 700 series, earning the nickname “Defense Calculator” due to its design for scientific calculations, particularly for the United States Air Force. It featured IBM's pioneering use of magnetic drum memory and introduced floating point arithmetic in computing.

The IBM 704, released in 1954, was the first mass-produced computer to feature core memory, enhancing both its computational speed and storage capacity. This system was also the first to support FORTRAN, an IBM software developed to simplify the programming process for scientific applications.

Introduced in 1958, the IBM 709 became synonymous with large-scale scientific computing. Utilizing vacuum tube technology, it was widely used by research laboratories and universities, cementing IBM's status in high-performance computing sectors.

The IBM 7090, a direct upgrade to the 709, was introduced in 1959, representing a shift to transistorized technology. It offered significant improvements in speed and reliability, supporting early space exploration efforts, including NASA's Mercury and Gemini missions.

The IBM 7040 and 7044, launched in the mid-1960s, were designed to offer powerful computing capabilities at a lower price point, targeting smaller research institutions and businesses. These models were part of IBM's strategy to broaden the accessibility of computing power.

IBM's 7070, introduced in 1958, was designed as a transistorized upgrade for users of the IBM 650, targeting business applications with its improved computational abilities and storage capacity, making significant inroads into commercial computing.

In 1964, IBM unveiled the System/360, a revolutionary family of mainframe computers designed to cover a full spectrum of business and scientific applications. The System/360 introduced microprogramming, solid-state memory, and a standard instruction set architecture (ISA), unifying previous disparate IBM architectures.

The IBM 7080, also launched in the early 1960s, was another transition model for users of the IBM 705. It provided enhanced data processing capabilities, aimed specifically at improving performance in commercial computing environments.

The IBM 7010, introduced in the early 1960s, was the final iteration in the 700 series to utilize vacuum tube technology. It was designed as an upgraded version of the IBM 7090, targeting the same scientific and military computing applications.

The IBM 7000 series mainframes were notable not just for their hardware advancements but also for their role in the evolution of software. Systems like the 7090 and 7094 were instrumental in the development of early operating systems, including IBSYS and IBJOB, and languages like FORTRAN and COBOL.

Though early in the networking and communication era, the IBM 7000 series began to incorporate basic network protocols for data sharing and communication. Technologies such as Binary Synchronous Communications (BSC) and the introduction of Systems Network Architecture (SNA) in later models facilitated the early stages of networked computing.

During the era of the IBM 700/7000 series, competition came from companies like UNIVAC, Honeywell, and Burroughs. These companies also developed mainframe computers, creating a competitive landscape that spurred rapid advancements in technology and software development.

The IBM 700/7000 series mainframes left a lasting legacy on the computing world. They were crucial in the development of computational science, the expansion of the commercial computing market, and laid the groundwork for IBM's future in the industry.
