LogicSim 2.7.2b LogicSim is a Macintosh application which allows for the creation and testing of electronic circuits. This design application allows you to place a variety of logic gates, wires and gadgets to create and simulate electronic circuits in real time. This application comes with a full-fledged manual, examples, parts and families. This app works on Mac OS 6.0.8+, but it will NOT properly function on Mac OS 7.0 - 7.1. To combat this, you will need the Drag&Drop Extension (provided with LogicSim). Enjoy! More coming in Wave 2! Requirements: CPU: 68000 RAM: 4MB OS: Mac OS 6.0.8 - 7.1 (needs extension), 7.5+ Disk Space: 1.4MB
