This was not part of the MAS 714 class material. It is the project that comes with the version of scratch "Scratch14Feb04" Press T to see some of the original code.
It seems odd that the "green flag" is not what starts the project. This version of Scratch used different colored flags to send and receive broadcasts. It also had a screen size of just positive numbers. (0,0) was at the top left corner and sprites could be hidden by having them go completely offscreen.
