MMLogic is a point-and-click schematic generator/logic simulator for Windows 95 (or Windows 3.1, if you have Win32). Currently a beta test version is free.

MacOS only

LogicSim is a very useful, easy-to-use schematic generator and logic simulator for Macintosh. You can download the stuffed, binhexed package by clicking here. The Motorola 680x0 version is postcardware. That means that if you use the program regularly, you have an obligation to send the author a nice postcard. Since the author is French, I sent a postcard of Reunion Tower in Dallas, which is named for a French colony that existed here in the 1830's. The PowerPC version will be $20 shareware.

Java (UNIX / MacOS / Windows 95 only)

The University of Hamburg, Germany has developed an excellent set of Java applets that demonstrate the principles of CMOS devices and gates.
