GrayBox enables you to run classic Mac apps on Mac OS X... without "Classic"!
GrayBox is similar to Apple's BlueBox/Classic. Like Classic, GrayBox interleaves its windows as peers to those of native apps. Unlike Classic, GrayBox runs each app in its own protected memory space.
GrayBox runs only early B&W apps. Currently, it has been tested only with MacDraw 1.9.5; see http://
