The
IBM 1400 series were second generation (
transistorized) mid-range business
computers that
IBM sold in the early
1960s. They could be operated as an independent systems, in conjunction with IBM punched card equipment, or as auxiliary equipment to other computer systems.
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
IBM 1460 was 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The 1400's were officially withdrawn in the early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 operational status by the
Computer History Museum.
