WILLOWS EXTENDS TWIN APIW TO MACINTOSH DEVELOPERS TWIN APIW for Macintosh Available in Developer Release 1 Version for Cross-Platform Windows to Macintosh Development San Jose, CA -- May 13, 1996 -- Apple World Wide Developers Conference -- Willows Software, Inc. today announced the availability of the Developer Release 1 (DR1) version of TWIN APIW for the Macintosh. Designed to create a simplified migration path from Windows applications to other platforms, TWIN APIW allows developers to write to the familiar Windows Application Programming Interface (API) and deploy on other desktop platforms with one development effort. The DR1 version for the Macintosh signifies availability of the first non-proprietary Windows to Macintosh [development] porting tool kit. "TWIN APIW for the Macintosh gives developers an early view of technology that will allow them to develop Windows applications for the Mac OS," said Rob Farnum, president of Willows Software, Inc. "Macintosh developers will appreciate that TWIN allows them to use Macintosh tools and compilers during development. Traditional solutions have forced Macintosh developers to use existing Windows tools. We understand the importance of maintaining a familiar environment for developers, particularly Macintosh developers who have a strong devotion to Macintosh tools." "Other companies claim to have truly cross-platform solutions, but we are the first with an open, non-proprietary Windows to Macintosh tool that works within the Mac IDE. This is a huge step toward our vision of application-driven development, in which developers can build the best applications for customers, independent of platform," continued Farnum. "The platform is the dominant factor for developers and customers. We hope to change that." In addition to allowing Macintosh developers to capture Windows market share, TWIN APIW for the Macintosh will benefit end users with installed bases of Macintosh computers. TWIN technology stretches the value of hardware and systems by extending the target desktops upon which applications can be deployed. Developers will be able to easily and efficiently build and deploy their favorite Windows applications on Macintosh computers within their organizations. TWIN APIW for Macintosh will greatly increase the number of applications available for this popular platform. Additionally, TWIN APIW for Macintosh has no ties to Windows source code and no run-time royalties. TWIN Technology TWIN APIW for the Macintosh is a source porting kit that allows developers to migrate their applications to the popular Mac OS. The product allows developers to maintain a single source base, which greatly reduces porting costs and time to market. In addition, TWIN APIW lets developers combine source code and existing Intel binary objects (i.e., DLLs) to take advantage of third-party component technology without requiring vendor source code. TWIN APIW for Macintosh is a toolkit designed to leverage existing Windows application sources in a Macintosh developer environment. The product is integrated into the Macintosh environment allowing developers to utilize their existing compilers and debuggers for building native PowerPC based applications. These features will enable Macintosh and Windows developers to take full advantage of both markets and the development tools that are optimized for these markets. "Willows' TWIN APIW for Macintosh is an exceptional solution for porting Windows applications to the Macintosh platform," said Heidi Roizen, vice president for Apple Developer Relations. "Apple is very fortunate to be able to offer this solution to its developers, and we look forward to working with Willows as they move toward the final release of this tool." George Sutty with GSL Graphic Software Labs in Huntington Beach, CA, moved his Backgammon by George program over to the Macintosh in less than one day. "I moved 11,000 lines of code over to the Macintosh in about six hours. Any other solution would have taken much longer and cost me thousands of dollars more." TWIN APIW Extensibility As the Windows API evolves and is enhanced by Microsoft, TWIN APIW will remain compatible through built-in extensibility. TWIN gives developers the ability to enhance the API to include specialized application functionality as needed. Similarly, Willows will act as a consultant to companies who want to add specialized API functionality, but do not have the resources to do the work themselves. Willows is also working with international standards organizations to promote the APIW as an open, industry-wide standard. TWIN APIW DR1 for the Macintosh Users can register to download a free copy of the Macintosh TWIN APIW DR1 technology through Willows' World Wide Web site at http://www.willows.com. Users can also order a $250 annual subscription to receive quarterly updates of a CD-ROM that includes source, binaries and documentation for all platforms. In addition, developers must purchase a $250 re-distribution license per platform for each application built using TWIN technology. Willows' goal is to partner with these initial developers to provide the technology, the support infrastructure, and the information that will enable them to meet the cross-platform needs of their customers. Willows Software, Inc., Saratoga, California, is unique in its mission to be the leading supplier of products and services based on an open and standard Windows API. Willows' technology allows developers to focus on building the best possible applications, independent of platform, and deploy them on Windows, Macintosh, UNIX and Netware platforms with little or no development effort. ### Darcy Fowkes Marketing Communications Willows Software, Inc.
