Introduction Your Epson® Equity™ II personal computer is a versatile, highperformance system which offers you a wide variety of choices. First you choose between two models of the Equity II main unit. Then you select the peripherals you want to use with it to assemble the configuration that does the most for you.
How To Use This Manual This user’s guide explains how to set up and care for the Equity II. It also describes how to connect optional equipment and start using your system. Follow the instructions in Chapter 1 to set up your system. Chapter 2 describes how to turn on the Equity II and gives general operational procedures. Chapter 3 explains how disks and disk drives work and shows you how to use them. Chapter 4 describes how to install and remove option cards.
Chapter 1 Setting Up Your System It won’t take you long to get your Epson Equity II personal computer up and running. This chapter describes the Equity II main unit and shows you how to set up your system and make any necessary adjustments.
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. Soft surfaces like beds and carpeted floors attract static electricity, which erases data on your disks and can damage the computer’s circuitry. Soft surfaces also prevent proper ventilation. Good air circulation. Air must be able to move freely under the system as well as behind it.
Arranging the Components First decide how you want to arrange your system components. You can set up the Equity II main unit horizontally or vertically. In the horizontal position, the main unit lies flat with the monitor on top of it and the keyboard directly in front. Figure l-l shows this arrangement. Figure 1-1.
In the vertical position shown in Figure 1-2, the main unit stands upright on its side with the keyboard and monitor beside it. The feet on the right side serve as the base when the main unit is vertical. If you choose the vertical position, contact your Epson dealer about a mounting kit to stabilize the computer. Figure 1-2.
The Front Panel Figure l-3 shows the front panel with the covers open to reveal the computer’s DIP switches and the keyboard cable socket. To open the covers, press down gently on each of the small handles and pull out.

Back panel The back panel components work as follows: Switched AC outlet. Auxiliary power outlet. You can plug the power cord of an IBM-compatible monochrome monitor into this outlet, if the monitor’s power consumption does not exceed 1 amp. The main unit’s power switch controls the monitor connected to this outlet.
Direct-drive video port. Internal video interface connector. You can plug a TTL monochrome or an RGB color monitor into this nine-pin female D-connector. See “Setting the DIP Switches” in this chapter to find out how to set switches l-5 and l-6 to match your monitor type. RS-232C serial port. Allows you to connect a peripheral with a serial interface, such as a modem, another computer, or a printer. Parallel port. Allows you to connect a peripheral with a parallel interface, such as a printer or a plotter.
Connecting a Video Monitor The Equity II has a built-in video interface for connecting a monitor. The exact procedure you use to connect your monitor to the main unit depends on the type of monitor you have. See your monitor manual for detailed instructions or follow these general guidelines: 1. Place your monitor on top of or near the Equity II main unit. It is easiest to connect the monitor cable if the back of the monitor and the main unit face you. 2.
If you have a composite video monitor, connect the appropriate end of the monitor cable to the composite video port on the back panel. If you want to use a different monitor with a video interface card, install the option card as described in Chapter 4. Then connect the appropriate end of the monitor cable to the connector on the option card. 4. Plug the monitor’s power cable first into the power inlet on the monitor and then into an electrical outlet.
To connect the cable, open the front panel cover and insert the keyboard connector as shown in Figure l-7. Do not force the connector, but be sure to insert it all the way. See that the cable exits to the right of the main unit. Gently push the cable into the retaining clip, and close the cover. Figure 1-7.
You can use the keyboard in different positions-including flat on a desk or on your lap. You can also adjust the keyboards legs to tilt the keyboard up. Just turn the keyboard over and lift each leg upward until it locks into place, as Figure l-8 shows. Figure l-8. Adjusting the keyboard legs To disconnect the keyboard, open the cover on the front panel and press down on the retaining clip to release the cable. Lift the tab on the keyboard connector and pull it straight out from the main unit.
To connect a printer to the main unit, you need an IBM PCcompatible printer cable with a 25-pin male D-connector on one end. If you are not sure which cable 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 1-9. Figure 1-9. Printer placement 2.
locks Figure 1-10. Connecting a printer 5. Plug the printer’s power cable into an electrical outlet. Note: You can plug some printers into the unswitched AC outlet on the back panel, if the printer’s power consumption does not exceed 1.5 amps. Serial interface If you have a printer (or another peripheral such as a modem) with a serial interface, connect it to the port marked SERIAL on the back panel of the main unit.
Setting the DIP Switches You set the DIP switches on the Equity II to provide your system with information about itself. This information includes monitor type, number of floppy disk drives, and which built-in interfaces are in use. Some software programs do not operate properly if your DIP switch settings do not match your hardware. Although your dealer probably set your DIP switches for you, read this section to be sure your settings match your system configuration.
DIP switch set 1 Table l-l and the descriptions below explain how to set the DIP switches in set 1. Note: Switch l-3 is not used. Leave it off. Table 1-1. Set 1 DIP switches 1 Floppy drive A: 360KB 1.2MB Coprocessor: Installed Not installed 2 ON OFF 4 5 6 7 8 J OFF ON Switch 1 (floppy disk drive A)--This switch tells the computer what type of A drive it has. If your Equity II has a 360KB floppy disk drive in the top slot, turn on switch 1-1. If the top slot contains a 1.
Switch 4 (internal parallel interface)-To use two or more parallel devices (usually printers), you need to designate the built-in parallel interface as either primary or secondary. In MS-DOS, you would then refer to it as LPT1 or LPT2 respectively. To use the built-in interface as the primary device, turn off switch l-4. If you have not installed extra parallel interfaces, the built-in interface is the primary device regardless of how you set this switch. You cannot disable the built-in parallel interface.
Table 1-2. Set 2 DIP switches Switch 5 (parity checking,)-Parity checking is the method your computer uses to detect any errors in RAM. If you enable parity checking and the computer detects an error in memory, an error message displays. For maximum protection, turn off switch 2-5 to enable parity checking. To disable parity checking, turn on this switch.
Chapter 2 Using the Equity II After you set up your system, you’re ready to turn on the power and start using your 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 disk protector sheet in a disk drive. Do not attempt to dismantle any part of the computer. Only remove the top cover to install and remove option cards.
Turn on the monitor so you can see the messages that appear as the computer starts up. If you have a printer or any other peripheral, turn it on next. You can turn on the computer with or without a system diskette in the top disk drive. For now, leave the drive empty. To turn on the computer, open the cover on the top right comer of the front panel and press the power switch. The power LED lamp next to the power switch lights up and the cooling fan inside the main unit starts.
You need to prepare your hard disk before you can run an operating system on it. Refer to “Using a Hard Disk Drive” in Chapter 3 and your MS-DOS (or other operating system) manual for instructions on how to prepare a hard disk for use. When your hard disk is set up to automatically boot MS-DOS, the operating system loads when you turn on the computer.
3. Push the diskette into the slot until it clicks into place. Be careful not to force it. 4. When the diskette is in all the way, press the PUSH button on a 360KB floppy disk drive, or turn the latch on a 1.2MB floppy disk drive clockwise until it locks into the vertical position. This keeps the diskette in place while you use it, and enables the read/write heads in the disk drive to access the diskette.
Table 2-7. Special keys I Kev I Shift Alt Caps Lock Num Lock Enter I Purrbose .~ I Moves the cursor to the right in normal mode and to the left in shift mode. Referred to as the tab key Works with other keys to perform special (control) functions, such as editing operations in MS-DOS and GW-BASIC. Produces uooercase characters or svmbols when used with the main character keys. Produces lowercase characters when Caps Lock is on.
Selecting an Execution Speed The Equity II can operate at two different execution speeds. You choose between a 4.77 or a 7.16 MHz clockrate. At the faster speed, the Equity II performs all tasks more rapidly. You can select the slower execution speed to run application programs that have specific timing requirements. To select the execution speed you want the computer to start up in, use the MS-DOS SETUP program.
There are three ways to reset. Because each is more powerful than the last, try them in the order listed here: 1. If you are using MS-DOS, hold down Ctrl and Alt and press the Del key on the numeric keypad at the right of the keyboard. The screen goes blank for a moment and then MS-DOS reloads. (The operating system must be on either the diskette in the top drive or the hard disk.) If this does not correct the problem, try the second method. 2. Press the reset button under the cover below the disk drives.
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. The Equity II can have up to two disk drives. The top disk drive on the Equity II is a floppy disk drive and you can have a hard disk drive or one of two types of floppy disk drives below it. (The introduction in this book describes the available Equity II disk drive configurations.
Choosing Diskettes for the Equity II 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 correct format type for the drive(s) in your Equity II. The top floppy disk drive on the Equity II has a storage capacity of 360KB (kilobytes) and uses 5 %-inch, double-sided, double-density, softsectored, 48 TPI (tracks per inch) diskettes.
You can use a double-density diskette in a 1.2MB drive if you format it as a 360KB (or 320KB) diskette in the 1.2MB drive first. (Your MSDOS or other operating system manual explains how to format a diskette in the density you choose.) After you do this, you can read data from it in both drive types, but write to it 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.
Caring for 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: Never remove a diskette from a drive or turn off the computer while a disk drive’s LED lamp is on. The red light indicates the computer is copying data to or from a disk. If you interrupt this process, you can lose data. Remove all inserted diskettes before you turn off the computer. Never touch a diskette’s magnetic surface.
If you have a hard disk drive, take these additional precautions: l l l Never turn off the computer’s power when the hard disk LED lamp is on. The red light indicates the computer is 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.
Write-protecting diskettes As shown in Figure 3-1, the right edge of a diskette has a small, rectangular notch. If this notch is visible, you can copy new data to the diskette. If you cover the notch with an adhesive write-protect tab, you can retrieve and copy data from the diskette, but you cannot store new data on it or delete any files it contains. If you try to change data stored on a write-protected diskette, an error message tells you the diskette is write-protected.
Since 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 drive 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.
The MS-DOS system diskette contains all these programs and the MS-DOS manual describes how to use them. 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 an operating system.
Chapter 4 Installing Option Cards Option cards are accessories you can install in your Equity II to provide extra capabilities. For example, you can add a hard disk, another monitor, an auto-dial modem, or a mouse. The Equity II has five slots for S-bit option cards so it can hold up to five cards. If your Equity II has a hard disk, a hard disk controller card occupies one option slot. You can buy option cards from Epson as well as other vendors.
2. As shown in Figure 4-1, the back panel is secured with three screws. Remove the screws with a Phillips screwdriver and put them safely to one side. Then remove the back panel from the main unit and set it aside. Figure 4-1. Back panel screws 3. The top cover is secured by four screws, two on each side of the computer. Locate the small plastic inserts that cover the two screws on the left side, as shown in Figure 4-2. Remove the plastic inserts with a small screwdriver and set them aside.
Figure 4-2. Side screws under plastic inserts 4. Figure 4-3 shows how to tilt the cover up and remove it from the computer. Set the cover aside for now. Figure 4-3.
Installing an Option Card You can install most option cards in any available slot. However, some cards work only in a specific slot. If you have such a card, your option card manual tells you which slot you need to use. Since the hard disk controller card must be connected to the hard disk, this card occupies slot 5, which is closest to the hard disk. To install an option card inside the Equity II, follow these steps: 1.
5. Once the connector pins are sitting in the connector slot, push the card downward firmly (but carefully) to fully insert it as shown in Figure 4-4. 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. Figure 4-d. Inserting an option card 6. Secure the card’s metal retaining bracket to the back of the computer with the retaining screw. The piece of foam in the main unit’s cover holds long option cards in place at the free end. 7.
Notice that each access slot cover on the back panel is secured by a tab at the bottom and a clip at the top. Locate the access slot cover that corresponds to the position of the option card you installed. Then hold the back panel of the computer with the inside facing you. As shown in Figure 4-5, push down on the clip at the top and push out to remove the cover. Figure 4-5.
4. Replace the back panel and the three screws across the top edge. 5. Reconnect the main unit to the monitor, the keyboard, the printer, and any other peripherals you have. 6. Turn the main unit so the front faces you and place the monitor back on top of the main unit, if that is where you keep it. 7. Check to be sure the power switch on the main unit is off. Then reconnect the power cable to the AC input on the back panel and to an electrical outlet.
Using a Mouse You can use a mouse with special software to enter data and direct a pointer on the screen. For example, you can point to an instruction on the screen and press a button on the mouse to perform the command. See the software manual that comes with the mouse, or the application program, for instructions on how to use it. If you need to install an option card to use the mouse, follow the instructions in this chapter to install it. Then connect the mouse’s cable to the connector on the card.
Chapter 5 Troubleshooting You should not encounter any serious difficulties as you set up and use the Equity II. 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.
2. Use the controls on the monitor to turn up the brightness and contrast. 3. Remove any diskettes and then turn off the power switches on the monitor and the main unit. Check that the monitor’s power cable is securely connected to the electrical outlet and that the monitor cable is properly connected to both the monitor and the main unit. Turn on both power switches again. 4. Turn off the power switches on both the main unit and the monitor. Then check the electrical outlet for power.
2. Have you inserted the right type of diskette? The diskette type is normally shown on the manufacturer’s label. In the top drive, which has a storage capacity of 360KB, use 51/4-inch, double-sided, doubledensity, 48 TPI, soft-sectored diskettes. If you have a second 360KB floppy disk drive, use the same type of diskettes in this drive. If you have a second floppy disk drive that has a storage capacity of 1.2MB, use 5?&inch, double-sided, high-density, 96 TPI, softsectored diskettes in this drive.
Software Problems If you have trouble with a software program, check the following list of problems and solutions: 1. The software program does not start. Check that you are following the correct procedure for your operating system. Make sure you insert the system diskette in drive A (the top drive). 2. An application routine does not work. Refer to the software manual and complete the routine according to the instructions.
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 instructions in the option card manual? 3. Did you set any necessary jumpers or DIP switches on the option card? See your option card instructions. 4. If you added an external device, do you have the proper cable to connect the peripheral to the option card connector on the back panel? 5.
Contact your Epson dealer to obtain a new lithium battery and follow these steps to install it: 1. Follow the instructions in Chapter 4 to remove the main unit’s cover. Locate the battery just behind the front panel on the side with the , Epson Equity II logo. 2. To disconnect the battery, grip the brown battery connector on the main system board and pull it straight up. 3. Remove the screw on the plate that secures the battery and set the screw and the plate aside. 4. Lift out the battery. 5.
