Smalltalk-76 Environment Demonstration

Public and internal demonstrations of the Smalltalk-76 environment showcased an interactive, graphical system where code, compiler, and debugger were integrated into a single, object-oriented user interface.

Significance

This wasn't a commercial product, but a conceptual prototype that laid the fundamental groundwork for all future graphical IDEs, demonstrating the power of direct manipulation, real-time feedback, and integrated tooling within a visual programming world.
