Second Generation Mainframes: The IBM 7000 Series describes IBM's
second generation of mainframe computers which introduced new
technology, new peripherals and advanced software. These systems
were continuations of the instruction sets of the IBM 700 series
with significant enhancements, but supported upwards compatibility
that preserved customers' investment in the earlier series. The use
of magnetic cores, fast magnetic tapes and disks, and transistors
yielded computation speeds that opened new domains for computation.
Programming languages continued to be developed and enhanced, and
new ones were developed for specific domains, such as SNOBOL,
COBOL, and Macro Assemblers. Robust subroutine libraries for
mathematical applications appeared. New operating systems provided
many capabilities to programmers for data management and file
systems, limited multiprocessing, timesharing, programming language
support, and better error handling and control of peripherals.
Early concepts in persistent file systems on magnetic disks were
developed that changed the nature of job processing. The IBM 7000
series led the way in many innovative concepts that helped to
establish IBM as the foremost manufacturer of computer systems.
However, the diversity of the models put significant strain on
IBM's financial resources and development teams, which ultimately
led to OBM's development of the System/360 family of machines.
