Using CPU Sim Help
The Help windows for CPU Sim include descriptions of the uses in detail of the menu items, the role and uses of various windows, and a complete description of what hardware, microinstructions, and machine instructions can and cannot be created using CPU Sim. These Help windows can be accessed through the "General CPU Sim Help" menu item in the Help menu or through the Help buttons which appear in most dialog boxes.
If the Help windows don't help, feel free to contact the author, Dale Skrien, at <djskrien@colby.edu> with your questions.
