General Information: Power Switch
---------------------------------
Power switches on compact Macintosh models are usually located on the back of the unit, near the left side. When facing the computer, you should be able to use your left hand to reach around to the back of the Macintosh and operate the rocker switch. When the computer is on, the top part of switch, marked with an "I," should be pressed in. The Power switch on the Macintosh Color Classic is on the back of the unit, near the right side.
General Information: Reset Switch
---------------------------------
The Reset Switch, also known as the Programmer's Switch is usually located on left side of compact Macintoshes. The exact position varies, but is usually near the rear of the unit, protruding from the vents near the base. There is no Reset switch on the Macintosh Color Classic.
There are two switches or buttons to press. The first, nearest to the front of the unit is the reset switch. Pushing the reset switch is the same as turning the power switch off and then on.
The second switch, nearest to the back of the unit, is the interrupt switch. This switch is used by Macintosh software programmers when writing applications and debugging them. Pushing the interrupt switch will produce a blank dialog box on the Macintosh screen. Programmers can then type codes to obtain the response or information they require from the Macintosh.
