Jim Collas has resigned as president of Amiga after less than nine months on the job, according to people familiar with the decision.
It was not clear why Collas left the post. Phone calls to the company were not immediately returned.
But the departure of Collas comes less than a month after the company orchestrated a high-profile coming-out party for the unit, which is a separate subsidiary of Gateway.
Gateway, which paid about US$13 million to acquire the rights to 47 Amiga patents, is attempting to revive the once-popular computer brand. Collas and other executives involved in the project had indicated interest in developing Internet-related products based around Amiga technology.
Collas, who held a variety of management posts during his seven years at Gateway, had eagerly pressed company CEO Ted Waitt and was subsequently granted the top job at Amiga in January.
He also urged Waitt to let him run Amiga as a separate company.
