Inferno, an operating system originally developed by Bell Labs for devices such as set top boxes and telephones, has been ported to Compaq's iPaq handheld computer.
Inferno is distributed by Vita Nuova Holdings, based in York, England, which also distributes the Plan 9 operating system, also developed by Bell Labs.
Vita Nuova said the port will be available in July. Inferno is not distributed under an open source licence, but its source code is readily available and can be modified.
