In some cases you may want to use a Power Macintosh computer without a monitor connected to it. For example, if the computer is an AppleShare IP server, running it without a monitor provides an additional level of security. Using a computer this way is sometimes called "headless" operation. Without a monitor, you can only administer the server using the remote administration software.
To use a Power Macintosh computer without a monitor connected to you it, you will need to connect a display adapter to make the computer behave as if a monitor were connected to it. You can use the monitor adapter that came with your computer if it was part of the accessory kit, or you can use a non-Apple adapter available from several third-party companies. Use the search keyword "monitor adapter" at the Macintosh Products Guide (http://www.apple.com/guide/) to find a third-party adapter. See Note 1.
For additional information on using a computer without a monitor connected to it, refer to these articles:
