A couple of mockup applications were seen in the 1983 demo, likely these are related although they have completely changed. These mockups don't actually do anything. The purpose of these mockups is to provide programming examples for developers as source code for these applications is included.

From one of the mockup applications, a dialog box demonstrating text boxes, pushbuttons, radio buttons and check boxes.

Another sample dialog box but this one uses buttons for "ok" and "cancel".

Exiting windows. Nothing really special, but it does give a better idea of where things were at the time.
