LogicLab (ver 25-Jul-2011) Abandoned Freeware LogicLab Simulates basic logic circuits. Quickly "wire-up" gates and flip-flops. Connect them to push buttons or clock generators, and watch 'em run. Red and green signal lines show the logic levels (0 or 1). A group of gates can be selected then dragged, duplicated, deleted, or deMorganized. XPL0 source code and numerous example project files are included. The program consists of the files "LOGICLAB.EXE" and "LOGICLAB.BMP". Saved LogicLab project files will have a ".LAB" extension. They can only be saved to the program directory. LogicLab can only load files in the program directory. LogicLab will create a file "_BACKUP_.LAB" for its internal use in the program directory.
