Mainstreet Computers: Setting the Standard Since 1982

Mainstreet Computers

Much has changed since Mainstreet Computers first opened its doors in the spring of 1982. The era of fax machines and traveling salesmen has given rise to email, video conferencing and internet marketing. Mainstreet Computers has remained a step ahead of our world's changing technology and effectively adapted it for the benefit of our clients.

In May of 1982, David Carnahan and Thomas Bowles began programming in COBOL. The software programs they produced were custom programs created exclusively for each individual client and designed to run on the UNIX operating system. It was not until 1985 that the first glass business expressed interest. A modified version of the software developed for that glass business became Mainstreet Computers' Glas-Avenue Software system. With the release of Glas-Avenue 1.0, designed for the Windows operating system, Mainstreet Computers experienced a multitude of glass businesses ready to automate.

Over the past 20 years, Mainstreet Computers has been the first to introduce many features to the glass industry including EDI, online ordering, and the first complete, in-house accounting package. The release of Glas-Avenue 8.0 debuts Glas-Avenue as never before - the most powerful and comprehensive glass-specific software product available.

In the early part of 2006, Mainstreet Computers opened a new division: Mainstreet Web Services. This new division's sole purpose is to broaden the advertising horizons of our clients by providing a strong, stable and effective presence on the internet.
