The aim of this project was to port an existing software for an Apollo machine to Windows.
The existing software was mostly developed with Fortran 77. The Fortran code contained complex physical calculations that had to be ported to windows very carefully to avoid calculation errors.
The new application, called test-circuit, was divided into a FORTRAN calculation module and a GUI module. The Fortran module was created by using the Absoft Pro Fortran Compiler Suite For Windows, the GUI by using Microsoft Visual C#.
The old software contained reports and plots, which were also developed in Fortran 77. Here, a different approach was taken for the new software. It was developed an interface to the software Origin, which displays all reports and plots.
