POWER light. When this light is red, it means that
the power is on and the system is running at
4.77MHz (megahertz). When this light is green, the
system is on and running at 8MHz. (Your Apex
operates at two different speeds. The difference
between these speeds is explained in Chapter 2.)
SPEED button. You can press this button to
change the computer’s running speed from
4.77MHz to 8MHz. When the button is pressed in,
your Apex runs at 8MHz; when the button is
released, it runs at 4.77MHz.
RESET button. You can press this button to reset
the computer. For example, when your MS-DOS
dkkette is in the top drive, you can press the
RESET button to reload the operating system. Be
careful not to press this button while your program
is running; you could lose data.
