PDA maker Palm has unveiled plans to launch new processors and an updated operating system (OS) at its developer conference in San Jose, California.
The system, known as OS 5, will be on display to developers ahead of its summer launch to enable them to work on making compatible programs.
Among the changes to the OS are improved security, virtual private networking and support for wireless networks. But not all old Palm programs will work with the new OS.
The company estimated that only 80 per cent of applications will be compatible because of non-standard techniques used to make programs run better on the current Palm chip.
This is despite emulation software being available to help old programs run on the new system.
The launch coincides with a move to a new class of processors which are expected to have clock speeds up to 10 times faster than the top of the range 33MHz Dragonball.
Palm will also formally announce the renaming of its OS unit as PalmSource at the conference today (5 Feb).
