Think Blue Linux

Think Blue Linux (sometimes "ThinkBlue Linux") was a port of Linux to IBM S/390 (later, zSeries) mainframe computers, done by the Millenux subsidiary of German company Thinking Objects Software GmbH.
The distribution consisted primarily of a collection of Red Hat Linux 6.1 packages (or RPMs) on top of IBM's port of the Linux kernel. Distribution of the product is scheduled to cease in early 2006, as most of its packages are out of date, and other Linux distributions support IBM mainframes. Most modern Linux distributions support IBM mainframes, making a special dedicated distribution unnecessary.
