Introduction Your Epson® Equity™ III personal computer is a versatile, highperformance system which offers you a wide variety of choices. First you choose between two models of the Equity III main unit, then you select the monitor and peripherals you want to use with it to assemble the configuration that does the most for you. The Equity III main unit is available in these models: l One 1.2MB (high-density) floppy disk drive l One 1.
The Equity III comes with the MS”-DOS operating system and the GW™-BASIC programming language. If you have used MS-DOS before on another computer, you will find that it works the same on the Equity III. Be sure to refer to your Equity MS-DOS manual, however, for descriptions of the special utility programs added by Epson. You may have purchased other software as well; you can use most software products designed for the IBM PC, PC XT, and PC AT on your Equity III.
Chapter 1 Setting Up Your System It won’t take you long to get your Epson Equity III personal computer up and running. This chapter describes the Equity III main unit and shows you how to set up your system and make any necessary adjustments. Unpacking When you unpack your Equity III, you should find the following: l The main unit and power cord l The keyboard with cable l An MS-DOS operating system diskette (version 3.
Choosing a Location Before you set up your new system, choose an appropriate place. Whether you use your computer at home or in the office, you need to find a comfortable, convenient location where it can run properly. Choose a location that provides the following: A large, sturdy desk or table. Make sure it can easily support the weight of your system, including all its components. A flat, hard surface.
Arranging the Components First decide how you want to arrange the different parts of your system. Figure 1-1 shows a typical setup. Figure 1-1. System arrangement Of course, if you have special computer furniture or want to customize your setup, you can arrange your system components to suit your own particular needs. Before you connect the cables, take a look at the front and rear panels of the main unit.
The Front Panel Figure 1-2 identifies the various components on the front panel.

Auxiliary power outlet. Some monitors (and other types of peripherals) can be plugged into the main unit here, instead of a wall outlet.
l Option card access slots. The Equity III has eight slots to hold up to eight option cards. Option cards allow your computer to control your peripherals or enhance your computer’s performance. One option card slot holds the hard disk controller card and another must hold a monochrome or a color/graphics video card to control your monitor. You can use the other slots to install additional options, such as a memory expansion card or a mouse.
Connecting a Video Monitor To connect the video monitor, place your monitor on top of or near the Equity III main unit. It is easiest to connect the monitor cable if the backs of the monitor and the main unit face you. Note: Your dealer probably installed a video card in your main unit to control your monitor. If not, you need to install it before you can connect your monitor. See Chapter 4 for instructions on how to remove the main unit’s cover and install an option card.
Figure 1-5. Connecting the monitor The monitor type must match the video card in the main unit. If you have a color card, you can use one of two connectors: a nine-pin, female D-connector for RGB monitors or an RCA connector for composite video monitors. 3. Plug the monitor power cable into an electrical outlet. Note: You can plug some monochrome monitors into the auxiliary outlet at the back of the Equity III main unit, if the plug fits and the monitor’s power consumption does not exceed .4 amps.
Connecting the Keyboard After you connect your monitor to the main unit, you can connect the keyboard. The keyboard cable is attached to the keyboard at one end. Insert the other end into the socket marked KEYBOARD on the rear panel of the main unit, as shown in Figure 1-6. Do not force the connector, but make sure you insert it all the way. Figure 1-6. Connecting the keyboard You can use the keyboard in various positions-including flat on a desk or on your lap.
Figure 1-7. Adjusting keyboard legs To disconnect the keyboard, unplug the connector from the rear panel. Be sure to pull the connector straight out from the main unit. Connecting a Printer The Equity III has built-in parallel and serial interfaces. You can easily connect a printer or plotter that has either type of interface-just follow the instructions below. Epson offers a full range of printer products. Consult your dealer for more information.
To connect a printer to the main unit, you need an IBM PC ATcompatible printer cable. If you are not sure which one you need, consult your Epson dealer. Once you have a printer cable, follow these steps to connect your printer to the parallel interface on the main unit: 1. Place the printer next to your system, as shown in Figure 1-8. Figure 1-8. Placing the printer 2. Before you connect the printer, be sure the power switches on both the main unit and the monitor are off. 3.
Figure 1-9. Connecting the printer 5. Plug the printer’s power cable into an electrical outlet. Serial interface If you have a printer (or another peripheral such as a modem) with a serial interface, connect it to the port marked RS-232C at the back of the main unit. The Equity III uses a DB-9P connector, so be sure you have a compatible cable. To connect a serial device, follow the same steps above for connecting a parallel device.
Checking the DIP Switches Inside the Equity III main unit, there are ten DIP (dual-line package) switches which give your computer information about memory size, monitor type, floppy disk drive interface, and which built-in interfaces are in use. Each switch has two positions: on and off. You may need to change these settings if you add options (such as extra memory or disk drives) to your system.
Chapter 2 Using the Equity III After you set up your system, you’re ready to turn on the power and start using your Equity III computer. But before you turn it on, read the following safety rules. Safety Rules Follow these rules to avoid accidentally damaging your computer or injuring yourself: Never turn the computer on or off with a protector sheet in the disk drive. Do not attempt to dismantle any part of the computer.
Key Lock The key lock allows you to disable the keyboard and lock the top cover of the main unit for security. This provides a safeguard against someone accessing confidential information or altering your computer’s internal hardware. The key lock also lets you run an application program, such as a screen demonstration, while disabling the keyboard so no one can alter the display. With the keyboard locked, the computer does not respond to anything you enter.
Powering Up Now you are ready to turn on your system. It is a good idea to turn on the monitor and any peripheral devices before you turn on the main unit. First, make sure the power cord is plugged into the power inlet on the rear panel of the main unit. Then plug the power cable into a 3-prong, l20-volt, grounded electrical outlet. Turn on the monitor so you can see the messages that appear as your computer starts up. If you have a printer or other peripheral device, turn it on next.
This tells you the computer can now load an operating system from a diskette in the top drive. The Equity III needs a disk operating system (DOS) to function. It comes with MS-DOS version 3.1. If you want to use another operating system, consult your dealer. To load an operating system, insert the system diskette you want to use (see ‘Inserting and Removing Diskettes” below). Refer to your MS-DOS (or other operating system) manual for details on how to use the system.
Figure 2-2. Inserting a diskette To remove the diskette, turn the latch counterclockwise until it is horizontal and the diskette pops out. Carefully pull out the diskette, place it in its protective envelope, and store it properly, such as in a special diskette container. If you have an optional 360KB floppy disk drive as well, insert the diskette the same way as for a 1.2MB drive. When it is all the way in, press the button labelled PUSH to lock it in place.
Special Keys on the Equity III Keyboard The dark gray keys on your keyboard serve special functions when your computer is running application programs. Figure 2-3 shows some of the more important keys and Table 2-1 describes them. Figure 2-3. Special keys Table 2-1. Special key functions Key I+-PI Ctrl Shift Alt Caps Lock Num Lock Enter t 22 Purpose Moves the cursor to the right in normal mode and to the left in shift mode.
The keys that contain LED lights (Num Lock, Scroll Lock, Caps Lock) work as toggles when you press them. When the light is on, the function is enabled; when the light is off, the function is disabled. Resetting the Computer You can reset the computer to load a different operating system or to reload the current operating system. For example, if an error occurs and the computer does not respond to your keyboard commands, you can reset the computer and try the same operation again.
Turning Off the Computer Before you turn off your computer, exit the program you are using and then remove all diskettes from the disk drives. If you have a hard disk, it is a good idea to run the MS-DOS program HDSIT to move the disk drive’s read/write heads away from the recording area before you turn off your computer. See your MS-DOS manual for instructions. Turn off your monitor and peripherals first, then turn off the main unit using the switch on the right side.
Chapter 3 Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and retrieve and use stored data when you like. All Equity III systems have at least one floppy disk drive; you may also have a hard disk drive and/or a second floppy disk drive in your system.
Choosing Diskettes for the Equity III When you buy diskettes, be sure to choose high-quality diskettes with reinforced hub rings. The added reliability is well worth the extra cost. You also need to make sure you buy the proper format type for the drive(s) in your system. The top floppy disk drive on the Equity III has a capacity of 1.2MB (megabytes) and uses %&inch, high-density, soft-sectored, 96 TPI (tracks per inch) diskettes. Each high-density diskette can hold 1.
either type of drive, but write to that diskette only when it is in a 1.2MB drive. If you write to it in a 360KB drive, it may become unusable in both drives. You can use a 1.2MB drive to read data from a double-density diskette that was formatted in a 360KB drive (for example, if you want to copy files from it). But do not write to this diskette while it is in a 1.2MB drive. If you do, the diskette may become unusable in both drives.
Caring for your Disks and Disk Drives To avoid damaging floppy and hard disks, you need to care for them properly. Take these precautions to avoid losing data: Keep disks away from dust and dirt. Small particles of dust or dirt scratch the magnetic surface and can destroy data. Dust can also ruin the read/write heads in a disk drive. Keep disks away from magnetic fields. (Remember that disks store data magnetically.
If you have a hard disk drive, take these additional precautions: l l l Never turn off the power to the computer when the hard disk drive light is on. This light indicates that the computer is currently copying data to or from the hard disk. If you interrupt this process, you can lose data. Never attempt to open the hard disk unit. The disk itself is enclosed in an air-tight container to protect it from dust.
delete any files it contains. If you try to change data stored on a writeprotected diskette, an error message tells you the diskette is write-protected. Write-protect tabs usually come with new diskettes when you buy them. Figure 3-1. Write-protect notch Using a Single Floppy Disk Drive Usually operating systems expect the computer to have at least two physical disk drives and display prompts and messages accordingly.
Because you may swap diskettes this way often, it is easy to forget which diskette is which. One way to avoid accidentally losing data is to hold the diskette for one drive in your left hand and the diskette for the other in your right. You can also place a write-protect tab on your source diskette. For more information on using a single floppy disk drive with MS-DOS, see your MS-DOS manual.
Note: If you plan to use an operating system other than MS-DOS, you need to use that operating system to partition the hard disk and copy the system files to it. The Epson hard disk is formatted at the factory. Therefore, you need not format it before you partition it to run your operating system. If you have serious read/write problems when you use it, you can format the entire disk as a last resort.
Chapter 4 Installing Option Cards Option cards are accessories you can install in your Equity III to provide extra capabilities. For example, you can add another disk drive, expand the computer’s internal memory up to 15.5MB, or connect a mouse. The Equity III has eight option card slots, so it can hold up to eight cards. A hard disk controller card occupies one slot (whether or not your system has a hard disk) and a card for your monitor occupies another.
F- , Figure 4-1. Top cover screws 4. Turn the main unit around so the rear panel faces you. Hold on to the two sides of the cover and carefully slide it straight back toward you, away from the front of the computer, as shown in Figure 4-2. Then lift the cover off and set it aside. Figure 4-2.
Installing an Option Card Figure 4-3 shows the eight option slots in the Equity III. 8 7 6 5 4 3 2 1 Figure 4-3. Option slots Slots 2 and 7 are designed for 8-bit option cards and the other six-slots 1, 3 through 6 and 8-are designed for 16-bit option cards. Figure 4-4 shows both types of cards. As you can see, the X-bit card has a second connector.
16=bit option card 8-bit option card Figure 4-4. 16-bit and 8-bit option cards As long as the card fits in the slot, it does not matter which slot an option card occupies. (For example, you can place some 8-bit cards in a 16-bit slot.) However, some cards work only in a specific slot. If you have Such a card, the instructions that come with it specify which slot you need to use.
Option cards fit in the slots only one way but be sure to examine the card first and follow the instructions closely. 1. Decide which option slot you want to use and then remove the retaining screw from the top of the metal slot cover on the rear panel. Keep the screw to secure the option card to the computer. Lift out the cover and keep it in a safe place in case you remove the option card later. 2. Unpack the option card and adjust any switches or jumper connections on it if necessary.
Figure 4-5. Inserting an option card 5. Once the connector pins are sitting in the connector slot, push the card downward firmly (but carefully) to fully insert it. If the card does not go in smoothly, do not force it-pull it all the way out and try again, being sure to keep it straight. 6. Secure the adapter plate on the end of the card to the back of the computer with the retaining screw. 7. If necessary, change the DIP switches inside the main unit. See “Setting the DIP Switches,” below.
Post-installation Setup After you install an option card (and replace the main unit’s cover and reconnect the power cord and peripherals), you need to run the SETUP program on the diagnostics diskette to update the configuration information. For example, if you add a hard disk, you need to run SETUP to tell the computer that it has the additional drive. See your diagnostics manual for instructions. Removing an Option Card To remove an option card, follow the same basic procedure you used to install it.

Switch l-l (memory size) tells your computer how much memory (RAM space) is available. The system always checks the amount of memory available when you reset your computer. The Equity III comes with 640KB of RAM, so be sure this switch is on. Switch 1-2 (monitor type) tells your system what type of monitor you are using, color or monochrome. If you have a color monitor, turn on switch 1-2. If you have a monochrome monitor, turn off this switch.
Replacing the Cover After you install (or remove) an option card or change DIP switch settings, follow these steps to replace the main unit’s cover: 1. Position the cover on the computer so you leave enough space to slide it back into place. 2. Slide the cover into place so the metal tabs go underneath the top edge of the front panel. 3. To secure the cover, replace the two screws on either side of the main unit. 4.
When you use the mouse frequently, clean the roller about every two weeks. First remove the roller cover. If you have an Epson mouse, turn it over, push the roller cover to the side, and lift the cover out. (If you have another type of mouse, turn the cover counterclockwise to remove it.) Then remove the roller, wipe it with a clean, dry cloth, and replace the roller and cover. There are no other user-serviceable parts inside the mouse.
Chapter 5 Troubleshooting You should not encounter any serious difficulties as you set up and use your Equity III. But if anything out of the ordinary happens, refer to this Chapter. Usually, such a situation requires nothing more than adjusting a cable connection, repeating a software procedure, or resetting the computer. You can use the suggestions here to solve most problems you may encounter. If the recommended solution does not work, consult an Epson dealer about servicing the computer.
The Video Display Does Not Appear If the computer starts up but no image appears on the screen, follow these steps to solve the problem: 1. Check to see that the power indicator on the video monitor is lit. If it is not, turn off the monitor’s power, wait 5 seconds, then turn the power back on. Wait to see if the display screen image appears. 2. Use the controls on the monitor to turn up the brightness and contrast. 3. Remove any diskettes, then turn off the power switches on the monitor and the main unit.
Floppy Disk Problems If you have trouble with a diskette, check the following questions: 1. Is the diskette damaged? Copy the diskette and repeat the operation that caused the problem using the copy. (If you have trouble copying the entire diskette, some of the sectors may be bad. Try to copy single files with the Copy command.) If the operation works using the copy, the original diskette is probably damaged. Make another copy to use as a backup. 2.
Hard Disk Problems If you have problems with your hard disk when you first start to use it, check to see if it has been set up properly. See “Using a Hard Disk” in Chapter 3 and refer to your MS-DOS manual. If you cannot access data stored on your hard disk, you may have accidentally repartitioned or reformatted part or all of the hard disk. If you have not done so and your hard disk does not function properly, have an authorized Epson service center check your hard disk.
Option Card Problems If you install an option card and get unexpected results, check the following questions: 1. Is the option card installed correctly? 2. Did you follow the setup and operation procedures in the option card instructions? 3. Did you set any necessary DIP switches or jumpers on the option card? See your option card instructions. 4. Did you set any necessary DIP switches in the main unit? See “Setting the DIP Switches” in Chapter 4. 5.
