In the late 1990s, the electronics industry was rapidly evolving, with a growing demand for efficient and reliable printed circuit board (PCB) design software. It was during this time that Protel Technology, an Australian-based company, released Protel 99 SE, a revolutionary PCB design tool that would go on to become a industry standard.

Protel 99 SE may be a relic of the past, but its impact on the electronics industry is still felt today, and it remains an important part of the history of PCB design software.

Protel 99 SE was first released in 1999, and its name "SE" stood for "Special Edition." This special edition was designed to provide a more accessible and user-friendly version of the company's flagship product, Protel 99. The software was specifically created for engineers, designers, and manufacturers who needed a reliable and efficient tool for designing and producing high-quality PCBs.

For those interested in downloading Protel 99 SE, you can try searching online archives or websites that specialize in hosting vintage software. Please note that downloading and using software that is no longer supported by the manufacturer may pose security risks, and users should exercise caution when doing so.

Although Protel 99 SE is no longer supported by the manufacturer, it remains a popular choice among engineers, designers, and manufacturers who continue to use the software for their PCB design needs. The software's legacy can be seen in the many modern PCB design tools that have followed in its footsteps, offering similar features and capabilities.
