ZETA (operating system)

ZETA, earlier yellowTAB ZETA, was an operating system formerly developed by yellowTAB of Germany based on the Be Operating System developed by Be Inc.; because of yellowTAB's insolvency, ZETA was later being developed by an independent team of which little was known, and distributed by magnussoft. As of February 28, 2007 the current and last version of ZETA was 1.5.

On March 28, 2007, magnussoft announced that it has discontinued funding the development of ZETA by March 16, because the sales figures had fallen far short of the company's expectations, so that the project was no longer economically viable. A few days later, the company also stopped the distribution of ZETA in reaction to allegations that ZETA constituted an illegal unlicensed derivative of the BeOS source code and binaries.
