IBM 1130 In education and engineering

[Gabriel Zapata]

Un instructor de programación de computación está usando un IBM 1130 para enseñar el lenguaje de computación FORTRAN IV a los estudiantes de la Escuela Latina de Boston, 4 de octubre de 1966. También enseñaba el lenguaje APL. El IBM 1130 Computing System, de 16 bits, introducido en 1965, era el ordenador menos caro de IBM en ese momento y se comercializaba a mercados técnicos sensibles a los precios,

intensivos en informática, como la educación y la ingeniería. La versión de la escuela latina de US $41,000 incluía una unidad de disco extraíble barata (no visible en la foto). La máquina utilizó los circuitos compactos Solid Logic Technology (SLT).

For those who don't speak Spanish, the post above said:

A computer programming instructor uses an IBM 1130 to teach the FORTRAN IV computer language to students at the Boston Latin School, October 4, 1966. He also taught the APL language. The 16-bit IBM 1130 Computing System, introduced in 1965, was IBM's least expensive computer at the time and was marketed to price-sensitive, computer-intensive technical markets such as education and engineering. The Latin school's US$41,000 version included an inexpensive removable disk drive (not visible in the photo). The machine used Solid Logic Technology (SLT) compact circuits.

SORTING?   Really?  :-)

I guess he's leaving the details as an exercise for the students.

The program is using a direct index, k=1 to 3.  The choices are: 

A. An external sort, as sold by DNA Systems,

B. Use hashing, first used in 1950s.

With the advent of modern data base systems, e.g., SQL, I haven't sorted anything via a sort command or call since about 1980.
