The IBM 1400 series was a family of second generation (transistorized) mid-range business computers that IBM sold in the early 1960s as a replacement for unit record equipment. 1400-series 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.
History The 1401 was the first member of the IBM 1400 series. The IBM 1410 was a similar design, but with a larger address space. The last member was the IBM 1460, logically but not physically identical to a fully optioned 1401 with 16,000 bytes of memory. Members of the 1400 series included: Programming Languages Programming languages for the 1400 series included Symbolic Programming System (SPS, an assembly language), Autocoder (assembly language), COBOL, FORTRAN, Report Program Generator (RPG) and FARGO. Retirement The 1400 series was replaced by System/360 and low end machines like IBM System 3 and subsequently the System/32, System/34, System/36, System/38 and AS/400. The 1400's were officially withdrawn in the early 1970s, however some 1400-series peripherals were still sold with third generation systems. An IBM 1401 computer is being restored to full operationals status by the Computer History Museum. | ||||||||
