Connecting to the Apple III
Plug the connector into the Apple III’s Port C. The Apple III doesn’t have screw holes around Port C, so
make sure the connector’s thumbscrews don’t interfere with a firm connection.
Connecting to Port C
Configuring the Apple III
To configure the Apple III, you’ll need the disk System Utilities and your application startup disk. Your
Apple III Standard Device Drivers Manual describes this program. To configure your software, follow these
steps.
Start your Apple III with System Utilities.
Put the application disk in drive 2.
From System Utilities, read in the SOS.DRIVER file and look for a driver named .SERPRINTER,
.PRINTER, or .QUME. If you can’t find a suitable driver on your startup disk, check your System Utilities
disk for a file named SERPRINTER.DRIVER or PRINTER.DRIVER.
With the Edit Driver Configuration option, make sure that you’ve chosen a character driver working
through the built-in serial interface port. (It will have the notationn/a following the labelSlot No. on the Edit
Driver Parameters screen.)
Edit the configuration block according to Table D-1 (based on SERPRINTER.DRIVER).

Be sure to set baud rate to 9600, format to 8 bits, no parity, and set all delays to 0.
Generate a new system on each of your application startup disks.
To test your connection and configuration, start up the application you’ve changed and print something.
If it works, you have a successful connection. If there is a problem with the printout, see Chapter 5,
“General Troubleshooting.”
Appendix E: Configuring Serial Interface Cards
This appendix shows you how to configure the Apple Serial Interface Card and Apple Serial
Communications Card for use with the ImageWriter II. It also gives tips on installing cards not
manufactured by Apple Computer, Inc. This appendix assumes you have followed the instructions for
opening your computer and removing your serial card given in Chapter 3.
Never open your computer, handle its circuitry, or install an interface card, unless you have turned off the
computer’s power switch. This is important; you could damage your computer and interface cards by
working inside the computer while the power is on.
