interesante, sabes si hay soft para meterle al emu???

Creo viene con KDE
Nooo, es broma.
Un amigo de java, se interesó como para dar una clase referida a la historia de la compu.
Pero si tenes tiempo y te interesa, siguiendo los links podrás encontrar info.
off-topic: En algun momento que tenga tiempo, no sé cuando será eso.. me gustaría hacer una guia para instalar en pc un emu de mainframe.

Para dar mejor idea de que estamos hablando:




Programming the ENIAC

The ENIAC didn't have a memory to store programs. So programming the ENIAC means physically connecting the units by cables and turning switches to the appropriate settings. This work was done by six women whose jobs were called computers. They were chosen from a group of over eighty women that were calculating ballistic trajectories by hand.

In May 1945, yet before the ENIAC was formally completed, the World War II came to its end. That meant, the initial aim of computing firing tables for the artillery became obsolete. But the upcoming cold war required even more complex computations. So the first real task assigned to ENIAC during its test runs in 1945 involved millions of discrete calculations associated with top-secret studies of thermonuclear chain reactions ? the hydrogen bomb.

Se entiende? la "programación" del Eniac es enchufar/desenchufar cables.

A los yanquees les titiló la lamparita cuando ya estaba hecho,.. "comprando" patentes, te suena ???

Konrad Zuse's Plankakül Programming Language (1942-1945/6)

En este link tienes docs y applets, editor y compilador: http://www.zib.de/zuse/English_Version/index.html


Konrad Zuse used an unusual technique for the statements in Plankalkül. Each data item was denoted with V (variable), C (constant), Z (intermediate result), or R (result), an integer number to mark them, and a powerful notation was used to denote the data structure of the variable. The highlights of Plankalkül are:


Introduction of the assignment operation, for example: V1 + V2 => R1.
The sign => was introduced by Rutishauser(5) to the ALGOL 60 GAMM-committee, but the committee did not accept it.

Statements like V1 = V2 => R1. This means: Compare the variables V1 and V2: If they are identical then assign the value true to R1, otherwise assign the value false. Such operations could also be applied on complicated data structures.

Programming plans, calling sub-programs, and different stop criteria.

Conditional statements (but no ELSE statement).

Repetition of statements (loops).

Operations of predicate logic and Boolean algebra.

Powerful operations on lists and pairs of lists.

No recursion.

Data types like: floating point, fixed point, complex numbers.

Arrays, records, hierarchical data structures, list of pairs.

Arithmetic exception handling.

Applications to play chess are described on more than 60 pages.

Assertion(6) as was subsequently used in the EIFFEL and MODULA-2 languages.

Complicated expressions with parentheses and nesting.

The history of some important programming languages from 1945 to the present day by Horst Zuse .
It is undisputed that Plankalkül was the first programming language for computers in the world.
However, the influence of Plankalkül on other languages was minimal.
