WARNING: When using the AC adapter, always connect the adapter to the computer, and then connect the adapter to an AC power outlet.

  • Page 18: Memory: The Three Types

    Operation Memory: The Three Types Your computer comes with three types of memory chips. They differ in what they're for, how they store information, and how much of each is included. ROM - Read-Only Memory implies that the computer can read the con­ tents of these chips, but can't write anything new into them.

  • Page 19: Disks

    Operation Disks General Your computer uses soft-sectored 5-1/4", double-sided, double-density floppy disks. Let's take a look at some basic items about these disks. S T I C K- O N L A BEL WRI T E- P ROTECT NOTCH SPI N L E H �...

If you have a backup disk, you won't be losing valuable informtion. To make a backup copy of MS-DOS to use as a "working copy,"...

  • Page 26: Keeping Track Of Disk Space

    Operation A disk that has been previously used can be reformatted, but remember: Formatting a disk erases everything on it! So be careful. Make sure you do not reformat a valuable disk by accident. Keeping Track of Disk Space It's a good idea to keep track of the available space on your disk. Otherwise you may labor for hours on a document, only to find there isn't room to save the information on the disk.

  • Page 27: Keyboard

    There are keystrokes and sequences of keystrokes that are unique to this computer. The following chart compares the keystrokes of the Z-100 PC Keyboards with the Z-170 PC Keystrokes. Cross-Reference Chart Z-100...
  • Page 28 Operation The previous chart shows that the left Shift key performs the standard shift functions; while the right Shift key, when used with the dual function keys (Arrow Keys, Num Lock, and Delete) selects the upper functions of those keys. That way, both the shifted and unshifted functions of those keys can be generated.

  • Page 29: Icons

    Operation Icons I� I I�� The icon keys initiate the functions that make this computer much more than a basic lap-top computer. Most of the icon functions are available without booting MS-DOS, in other words, no disks are involved. Some of the icons have two different meanings. This depends on what you're doing when you press them.

  • Page 30: Calculator Icon

    Operation Another common use of the Disk Icon is to get back to a program after interrupting it by pressing some other icon. For instance, suppose you are running WordStar and you press the Calculator Icon to do some figuring. Pressing the Disk Icon will return you to WordStar.

  • Page 31: Function Keys

    Operation Function Keys The function keys make up the row above the icons. They are labeled Fl through FlO. Function keys are used for special purposes by some programs. In addi­ tion, when the World Map display is active, the computer also uses these keys to perform tasks such as changing the active calendar date, moving the Time Zone display, and calling up the Setup Menu.

  • Page 32: Alphanumeric Keys

    Operation Alphanumeric Keys These are the letter, number, and punctuation mark keys that are similar to their typewriter counterparts. Some of these keys also have secondary meanings. Those with small blue numbers are used as part of the calculator keypad after the Calculator Icon has been pressed.

  • Page 33: Modifier Keys

    Operation Tab/Back Tab - Moves the cursor to the next tab setting. Modifier Keys The Shift, Ctrl, and Alt keys are called "modifier keys" because they modify, or change, the meaning of some other key. The modifier keys are always used in conjunction with another key.

  • Page 34: Program Keys

    Operation Program Keys Basically, "program keys" have meaning only to business programs that are designed specifically to use them. However, these type of programs, such as spreadsheets, are becoming quite common. Refer to the program documentation to see if and how it uses the program keys. These are also called "cursor keys.

  • Page 36: Special Keys

    Operation Special Keys Generally, these are keys with additional labels printed on their front edges. In all cases, this front-edge meaning is activated by pressing the special key simultaneously with the Ctrl key. When pressed at the same time as the Ctrl key, Pause this command freezes the display of text on the screen.
  • Page 37 Operation r+ll The Break command, when used simultaneously Break with the Ctrl key, is used to stop certain programs as they're � running. For example, if you begin a Diskcopy routine only to realize that you can't find the disk you want to copy, enter Break to quit.

  • Page 55: Appointment Calendar

    Operation Appointment Calendar The Appointment Calendar is a useful feature that helps you keep track of a busy schedule. There are 4,000 bytes of NVRAM (non-volatile mem­ ory) available. This is what the computer uses for storing appointments. If you have the optional modem installed, it shares this memory with the phone numbers that you have entered for modem operation.
  • Page 56 Operation The four arrow keys in the lower right corner of the keyboard are used to move around the schedule display. The RETURN key can also be used to step through the time slots. The regular keyboard is used for entering text. When you are at the point in the schedule where you want to enter text, just begin typing.
  • Page 57 Operation When you've set the alarm for an appointment, the computer will beep five minutes before the appointment time. It will beep for seconds or until you press the ESC key or until you press SCH EDULE to activate the calendar. If you don't do any of these things, the computer will beep once again every minute for ten minutes.
