6. (a) If the original monitors window only had a number 1 , click on OK, and then click on Switch. This completes the process. (b) If the original monitors window had both a number 1 and a number 2, click on OK.

7. Close Monitors Window

8. Click on OK.

NOTE: Throughout the switching process, the mouse pointer might move to an entirely different screen position on the large display TV/monitor It might actually move off screen. Therefore, it may be necessary to move the mouse a considerable distance to locate the pointer arrow.

Switch back to Computer Monitor

Procedure:

1. Access Control Panels, monitors menu from the Apple Pull down menu on the large screen display.
   


2. (a) If a number 1 appears in the center of the monitors mini-window, double click on the options button and then select Display Video on RGB Monitor. Double click on the OK, and then double click on Switch. There is a time lag for this switch, so do not panic!
   
   (b) If both a number 1 and a number 2 appear in mini-windows, go directly to procedure number 3.
   


3. Drag the menu bar from number 2 to number 1. Double click on the Menu Bar above the number 1. This will be on the large display.
   


4. Move the mouse pointer to the computer monitor and click on OK.

Audio/Video Capture with an AV Macintosh

AV equipped Macintosh computers are capable of recording movies with sound from either a laserdisc, VCR or video camera. Just sounds can be recorded from any audio source, such as a microphone, a tape deck or a CD player. The files are saved as QuickTime movies that can be included in multimedia presentations. Unfortunately, this type of file requires a large amount of disc memory to save and playback. Therefore, it is usually best to limit the movie/sound to only a few seconds, and to store the files on a 3.5Ó disk. The video output from the VCR or camera is connected to the video input of the Macintosh. If sounds are to be recorded along with the movie, then the audio output/input connections are made in a similar fashion.

Some type of movie making software, such as Hyperstudioª or QuickFLIX!ª, is required to record and edit the movie segments. The Power Macintosh computers are shipped with the audio/video capture program, called FusionRecorderª, that can be found in the Apple Extras folder on the hard drive. To start working with FusionRecorderª, use the following procedure:

Procedure:

1. Double click on the Apple Extras folder to open it.
   


2. Open the next folder called For Power Macintosh AV Versions.
   


3. Next open the Audio/Video Capture folder.
   


4. Click on the FusionRecorderª program to open a recording window and you are ready to begin.
   


5. Using the pull down menu bar, set the size of the Record Window. This determines the size of the movie that will be recorded when you click the record button. Smaller movies can be recorded at a faster frame rate, resulting in a smoother playing movie that requires less memory to store.
   


6. Click the Record button to begin recording and the Stop button to end.
   


7. The new movie will then appear in a Player View format to allow previewing and editing options. Portions of the movie are selected by holding down the shift key while using the slide(or step button) to highlight desired segments of the movie.
   


8. When editing is complete, choose Save As from the File menu.
   


9. Select the ÒMake movie self-containedÓ radio button. This will insure that all files referenced by the movie will be stored directly in the movie file.
   


10. Enter a name for the file, and save it to a floppy disk on the desktop. There are other editing features that can be used to further modify the saved movie at a later date.
    

Videomicroscopes

Videomicroscopes can be used to display and capture images of microscale reactions, such as crystal growth or copper with silver nitrate solution. Commercially available videoscopes usually range in price from $900-$2500. An ordinary videocamera, either with a standard microscope or by itself, will also work quite well for microscopic study. A styrofoam donut should be cut out to both fit over the eyepiece of the microscope and rest against the lens of the camera to prevent scratching the lenses. The camera should be mounted on a tripod to hold it securely in place. Focus the microscope on the object, then use the zoom feature on the camera to focus the camera. Plastic 24-well reaction plates, ziplock bags or clear, Tic-Tac mint containers are suitable for reaction vessels. Use a desk lamp with a piece of white construction paper taped over it to serve as a light source for back lighting the objects.
