Next, plug one end of the data cord to the peripheral plug on the
Atari console, and the
other to one of the I/ O connectors on the
rear
of the Atari 810. This is shown in Illustration 2-2. Additional
peripherals can be connected via the unused I/ O connector.
If just one disk drive is being installed, the device code switch in
the back
of the Atari 810 should be set to 1. If 2, 3, or 4 drives are
to be installed, the swtiches should be set
as indicated on the
drive code diagram on the back of the Atari 810. This is shown in
Illustration 2-5.
Use a pen or screwdriver to move the switches to
the appropriate setting. Be certain that the power to the Atari 800
and 810 is off when setting the drive code switch.
Installing the Atari
820 Printer
The Atari 820 Printer includes the following items:
• Pri nter
• Roll of Paper
• Paper
Mandrell
• Ribbon
• Data Cord
• User 's Manual
• Attached Power Card
Never operate a
printer without the ribbon and paper installed.
Doing so may cause damage to the printing head solenoids. The
instructions for loading the ribbon and the paper in the Atari 820
are given in the operator's manual.
Once the Atari 820 has been loaded with paper and a ribbon has
been installed, plug the power cord attached to the unit into a
household outlet.
Next, plug one end of the data cord into the port labeled
'
peripheral' on the Atari computer console. If another
peripheral such as the Atari 810 Disk Drive has already been
installed via
the peripheral port, the Atari 820 can be connected
via the I/ O CONNECTOR port on the Atari 810 disk drive. Plug
the other end of the data cord into either of the I/O
CONNECTOR ports on the printer.
