Sine Systems Inc. has announced that it will end normal operations starting at the end of business day, Aug. 3, according to an email from co-owner Marc Pezzolla.

Pezzolla said that given recent setbacks, keeping Sine going was “simply not feasible.” The email from Pezzolla mentioned sadness over the recent loss of business partner, Susan Ford.

“Please know that while Sine Systems will be winding down, steps are being taken to handle warranty issues through the website and by email,” he wrote. “I would like to thank all of you for your support for Sine Systems Inc. for the past 28 years. It has been a pleasure to work with you and to serve the industry in some small way.”

More details will be posted as they become available.
