Atarl 850 Interface module
Prowriter. If you plan on buying a printer, be
sure that the software you want to use with the
printer will work with that particular printer
model.
Using an Interface
In order to use a non-Atari printer with an Atari
computer, however, you will need a peripheral
known as an
interface,
which is a device that
allows different
pieces of equipment to under-
stand each other's
signals
and work together.
For this purpose, the Atari 850 interface
module
is used. This
module
is a
small
box that connects
to the computer and printer by a
cable.
The only
Atari-produced printer that
needs
the 850 inter-
face module is the
Model
825. The 850 interface
module
is
also
used to hook up other types of
devices to your computer.
