interest in Linux as an operating system on its electronic devices. In 1998, it supported the Linux7K project that had been initiated by Ed Bailey at Red Hat, which was to port Linux to its Series 5 personal computer. The project was named after the Cirrus Logic PS-7110 chip of the Series 5. Although this project was one of the earliest attempts to port Linux to a handheld computer, it did not come to fruition for Psion. The project soon transitioned to an informal open-source software project at Calcaria.net that kept the name Linux7K. After the project transitioned again to sourceforge.net, the project's name was changed to a more general name PsiLinux, and later to OpenPsion. The project has developed Linux kernels and file systems for the Revo, Series 5 and 5MX, and Series 7 and netBook. In 2003–4, Psion Teklogix and its founder David Potter expressed interest in Linux as the operating system for its devices as it divested from Symbian. However, the only result of that interest was Linux as the operating system on a limited number of custom NetBook Pros designed for a hospital setting. The Embeddable Linux Kernel Subset project has produced a small subset of Linux that runs on Psion Series 3 PDAs.
