If you don't see the message "Welcome to the IIGS," go through the following checklist to try to identify the problem. If you can't identify the problem yourself, get help From a more experienced Apple II user or from your authorized Apple dealer.
If you suspect a loose connection, be sure to switch off the power and wait at least 30 seconds before you secure the connection.
¥ Make sure the computer is plugged into a power source.
¥ Make sure the monitor is plugged into a power source.
¥ If the computer and monitor are plugged into a power strip, make sure the power strip is switched on and plugged into a grounded outlet.
¥ Make sure the monitor is connected to the computer.
¥ Make sure the disk drive is connected to the computer.
¥ Make sure the computer is switched on.
¥ Make sure the monitor is switched on.
¥ Make sure you inserted the tour disk into the startup drive (as explained in "Identifying Your Startup Drive," earlier in this chapter).
¥ If you have a 5.25-inch disk drive connected to the computer, make sure that the disk drive is empty and that its door is open before you switch on the computer's power.
¥ Make sure you're using the correct disk. Eject the disk in the startup drive (following the instructions in the next section) and make sure it's labeled Your Tour of the Apple IIGS.
¥ Check the monitor's contrast and brightness settings. If you think one of these settings may be the problem, see the owner's guide that came with your monitor for instructions.
¥ If the image on your screen is rolling or out of alignment, hold down the Option and Control keys while you press and release the Reset key (marked with a triangle) at the top of the keyboard. Then press 2. This procedure restores the standard frequency settings for the United States so that your monitor will receive signals from the computer at the proper frequency.)
