The IBM 1130 (1965): "The first IBM computer to rent for
less than $1000 a month." Intended for use by scientists, engineers, and
mathematicians. One of the first computers to use removable magnetic disk
storage (IBM 2314 removable disk cartridges, 1MB each). Programmed mainly
in FORTRAN, also in COBOL, RPG, APL, and possibly Algol-60.
Primary user interface is punched cards or paper tape, but also
supports interactive use via its integrated (keypunch-based) console
keyboard or IBM 2250 Graphics Display Unit, with
hardcopy to the IBM 1403 line printer or slower drum
printer, or to the IBM 1627 hardcopy plotter. Memory size: 4-8K 16-bit
words. A followon model, the IBM
1800, was intended mainly for process control.
The IBM 1130 was a testbed for the first graphical user interface
The Reactive Engine, Ph.D. Thesis, University
of Utah, 1969). At Columbia University, 1130s were installed in
Watson Lab, Teachers College, and
Lamont-Doherty Geological Observatory. The 1130s at TC and Lamont were
connected with the Columbia mainframes as RJE stations. The Lamont
connection was probably the first instance of long-haul computer networking
at Columbia (December 1969).
