Pascaline (also known as the arithmetic machine or Pascal's calculator) is a mechanical calculator invented by Blaise Pascal in 1642. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as the supervisor of taxes in Rouen . [ 2 ]
In 1994, the simulator was used to extend the ISO 7185 IP Pascal "core" language to include features such as dynamic arrays. In 1995, a "check encoder" was created to target 80386 machine code, and a converter program created to take the output object files and create a "Portable Executable" file for Windows.
This suggests that the carry mechanism would have proved itself in practice many times over. This is a testament to the quality of the Pascaline because none of the 17th and 18th century criticisms of the machine mentioned a problem with the carry mechanism and yet it was fully tested on all the machines, by their resets, all the time.

There are software packages associated with each domain. The 1990 edition of the Los Alamos Accelerator Code Group's compendium [1] provides summaries of more than 200 codes. Certain codes are still in use today, although many are obsolete. Another index of existing and historical accelerator simulation codes is located at the CERN CARE/HHH ...

A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
Order-Code 13-4005. p. 124: […] The HP-35 is a totally serial computer. The adder is a BCD serial type […] The serial structure means less integrated circuit area must be allocated to interconnection lines and gating functions and an interesting trade off occurs.
