Our client required a solution that could import, edit, and export his textbook figures that are saved in the MacDraw file format. The client also had specific requirements for the features and user interface of the application, requesting that they emulate the simplicity and functionality of the original MacDraw application. A team of six students created DartDraw to fulfill the need for an intuitive drawing application that can import MacDraw files and export EPS files.

  • C:Macintosh Update
    - .. C: Macintosh Update Macintosh has changed a little since the enclosed manuals were printed. This manual update lets you know about improvements to the Finder and MacWrite. It also describes a new Font and Desk Accessory Mover and the Choose Printer desk accessory that are now included on the System Disk. You can put this update aside for now; you don't really need to know about the changes it describes until you've been working with Macintosh for a while. Most of the changes just give you more speed and power in using your Macintosh. • See Macintosh, your owner's guide, to find out how Macintosh works in general. • See the MacPaint and MacWrite manuals to find out how those applications work. • You can also take a guided tour or two, to let the Macintosh demonstrate itself. Updating Other Disks Each enclosed disk includes the new Finder and other system changes; other applications you purchase may not You might want to update each of your startup disks with the new Finder and other system changes. To update applications such as MacProject, MacDraw, or MacTerminal, replace their System Folders by copying the System Folder from the enclosed System Disk. See "Copying a Document, Folder, or Application to a Different Disk" in Macintosh, the owner's guide. Here are a few guid��ines about updating other disks: . • Before you replace a disk's System Folder, make a backup copy of the disk. See "Copying an Entire Disk" in Macintosh, the owner's guide. • Start up your Macintosh using one of the enclosed disks rather than thedisk whose System Folder you want to replace; you can't replace the System Folder of the current startup disk.
