The IBM 701, known as the Defense Calculator while in development, was announced to the public on April 29, 1952, and was IBM's first commercial scientific computer..
IBM's first computer was the IBM ASCC at Harvard University (later renamed the Harvard Mark I due to an argument between IBM and Howard Hathaway Aiken of Harvard) in 1944.IBM's first electronic computer was the IBM 701 in 1952.
IBM's first computer that was not produced as a one off contract machine was the IBM 701 in 1953. They made 9.
The first mainframe computer is generally considered to be the IBM 701, which was introduced in 1952. It was IBM's first commercial scientific computer and marked a significant advancement in computing technology. The IBM 701 was designed for scientific and engineering calculations and laid the groundwork for future developments in mainframe computing.
Actually any commercial computer by anybody that could be named was before IBM. Watson Sr. saw little future in electronic computing and did not want to build fast machines that would obsolete their Electromechanical Unit Record line. It took Watson Jr. and the Korean War to push IBM into making their first "commercial" compuuter: the Scientific IBM 701. Their first two true commercial computers: The IBM 650 and IBM 702 were introduced a year or two after the IBM 701.
First IBM PC (Personal Computer) was IBM model number5150, which was introduced on August 12, 1981.IBM's first electronic digital computer was the 701 Defense Calculator, introduced in 1952.IBM's first computer was the Harvard Mark I, in 1942, but it was electromechanical.
The IBM 701, their first computer available for sale, had 36 bits per word. This word size was used on all their 700 and 7000 series binary scientific computers.
IBM shipped its first electronic computer in 1953. Dubbed the IBM 701 Electronic Data Machines, only 19 units were made during a 3-year period.
The first simple "operating system" was a program called IBSYS that IBM released for the IBM 7090 transistorized computer in 1960. IBSYS was derived from a program IBM's customer General Motors had written for their IBM 701 and IBM 704 computers and contributed to the IBM computer users group SHARE. SHARE had rewritten General Motor's original program, calling it SHARE Operating System for the IBM 704 and IBM 709 which was the version adapted by IBM to make IBSYS. IBSYS was not like modern operating systems however and would now be called a batch monitor program..
IBM announced the IBM 701 on April 29, 1952. The first production machine sold, serial number 2, was delivered to Los Alamos Scientific Lab on March 31, 1953; it was installed and operational three days later.
ENIAC was one of the nation's earliest computers.
701 is prime, so 1 and 701.
