Giving presentations and needing a way to show the Newton screen to a large audience can be a problem without special visualizer equipment. The solution? Show the screen on the Mac, which is probably already connected to a large projection system.
This SKANKY DISGUSTING AWFUL PRETTY SURE IT WILL CRASH YOUR MAC AND NEWTON HACK is just a proof-of-concept. Performance sucks (about 1 update every 5 seconds). That's mostly because of the serial connection, and the fact that it's transferring about 12k of screen bits each update.
Launch the Mac application, then open the Newton application to connect.
Be sure to reboot the Newton when you're done playing around.
