The front panel
On the front panel you see the power light, the power switch,
and the keyboard cable socket. If you are using an Apex Plus,
your computer has two diskette drives. If you are using an
Apex Plus 20, your computer has one diskette drive and one
hard disk drive.
Here’s how the front panel components work:
Power switch. Press this switch to turn the main unit on
and off.
Power light. This light is on when the power is on. Your
Apex computer can operate at two different speeds. The
light is orange when the system is running at 4.77MHz
(megahertz). The light is green when the system is running
at 9.54MHz. Do not change the operating speed while you
are running a program. See Chapter 2 for more information.
Keyboard cable socket. Use this socket to plug the keyboard
into the computer.
