Mactivation

Mactivation 3.3 is an interactive neural network simulator that runs on all Apple Macintosh computers. Users can learn and investigate the concepts of associative memory in a two-layer parallel distributed processing (PDP) architecture. A graphical user interface provides direct access to units, connections, and patterns. Basic concepts of network operations can be explored, with many low level parameters available for modification. A comprehensive user's manual includes cell biology, simulated neurons and networks, learning and memory. Source code (circa 1987) is included. Freeware.
