YellowTAB is a Germany software firm that produces an operating system based on BeOS 5.1.0. They have not publically confirmed that they have the BeOS source code or what their licensing agreement with BeOS s owners PalmSource is, but it is likely that whatever arrangement they have is legal, at least in Germany. Their product is sold as yellowTAB Zeta .

The company s offices are in Mannheim, and it s corporate motto is Assume The Power . The price of ZETA has raised eyebrows as ZETA costs almost twice what BeOS R5 Professional did.

YellowTAB has come under some criticism from the BeOS userbase, who claim that the company does not give back what it takes from the Haiku (operating system) project and other open source BeOS projects. In many cases, open source programmers have recreated yellowTAB s extensions to BeOS, most notably their SVG graphics extensions to OpenTracker. However, yellowTAB s actions to date have not violated the BSD Licence/MIT Licence licences under which most open source BeOS projects exist.
