These sample GEM applications were originally released by Digital Research in the UK:

• Alarm shows a GEM application (I wrote it) talking to a DOS Plus background program;
• Cube draws a rotating cube illustrating drawing techniques;
• Display illustrates writing a desktop accessory, to display the contents of a file;
• Terminal illustrates writing a desktop accessory, a terminal emulator;
• Training samples used by Digital Research on their GEM Programmers' course.
