The IBM 1400 series was a family of mid-range buisiness computers that IBM sold in the early 1960s as a replacement for unit record equipment. 1400 machines stored information in magnetic cores as variable length character strings terminated by a special flag. Arithmetic was performed character-by-character. Input and output was on punch card, magnetic tape and high speed line printers. Disk storage was also available

Members of the 1400 series included:

Programming languages for the 1400 series included Autocoder ( assembly languageAssembly language or simply assembly is a human-readable notation for the machine language that a specific computer architecture uses. Machine language, a pattern of bits encoding machine operations, is made readable by replacing the raw values with symbo), COBOLCOBOL is a second-generation programming language. Its name is an acronym, for CO mmon B usiness O riented L anguage defining its primary domain in business, finance, and administrative systems for companies and governments. Prehistory and specification C, FORTRAN and Report Program Generator (RPG). The 1400 series was replaced by System/360The IBM System/360 S/360 is a computer system family announced by International Business Machines on April 7 1964. It was the first family of computers making a clear distinction between architecture and implementation. The chief architect of the S/360 wa and low end machines like IBM System 3, System/32The System/32 is a single user minicomputer marketed by IBM in the mid- to late 1970s. It was used primarily by small to midsize businesses for accounting applications. RPGII was the (main) programming_language for the machine. The computer looked like a, System/34The System/34 was a minicomputer marketed by IBM in the early 1980s. It was a multi-user, multi-tasking successor to the single-user System/32. Like the System/32 and the older System/3, the System/34 was primarily programmed in the RPG II language. One o, System/36, System/38 and AS/400. The 1400's were officially withdrawn in the early 1970s.
