PalmSource Announces New Palm OS Developer Suite

Eclipse Powered development tool chain is key component in Developer Suite for ARM-native and 68K software development
 
ANAHEIM, Calif., EclipseCon, Feb. 2, 2004 — PalmSource, Inc. (NASDAQ: PSRC) provider of Palm OS®, a leading operating system powering next generation mobile devices, today announced its Palm OS Developer Suite to broaden the development and deployment of next generation enterprise, multimedia and wireless applications for Palm Powered™ smart mobile devices. The new tool chain is designed to provide software developers with an easier and faster path toward creating Palm OS applications for all current releases of Palm OS and Palm OS 6. In-depth technical details, and a preview version of the product, will be provided at the PalmSource Developer Conference in San Jose, CA on Feb 10-12, 2004. For more information on the developer conference visit http://www.palmsource.com/events.
 
The new Palm OS Developer Suite includes an open-source Integrated Development Environment (IDE) based on Eclipse, originally developed by IBM. Eclipse is a commercial-quality, best-in-class IDE with several hundred plug-in tools that support many major software development languages including C, C++, Java, and COBOL. The introduction of the Palm OS Developer Suite is critical to developers targeting support for both 68K and ARM-native Palm OS applications.
 
"As a leading mobile platform provider, PalmSource is committed to providing its 275,000 developers with high-quality tools to enable the creation of innovative software applications that extend the functionality of Palm Powered smart mobile devices into new markets," Larry Slotnick, chief products officer, PalmSource, Inc.
 
"Development environments like those supplied by PalmSource are popular now and growing more important to the future of computing technology and the Eclipse ecosystem," said Skip McGaughey, spokesperson for Eclipse. "As PalmSource developers gain experience with the Eclipse Platform and extend these tools, they'll be prepared to apply those skills to a broad range of computing solutions."
 
PalmSource has joined Eclipse as a founding Add-In Provider member, and is looking forward to collaborating with the organization, projects and other members during a two-year term. As an Add-in Provider member, PalmSource will participate in setting the direction and strategy of Eclipse components. PalmSource will also participate in Eclipse Open Source projects that are implementing various components, including the Eclipse Platform, C/C++ Development Tools (CDT), and the Java Development Tools (JDT).
