Atari wanted to ensure that it supplied any and all necessary parts and
peices for connecting peripherals up to its computer systems.
Shown above are some of the cable kits which Atari sold. The
modem cable kit was a DB-9 male to DB-25 male to allow connection of standard
modems to the Atari 850 interface. The Terminal cable was the
same but wired so that a teletype or display terminal could be connected
to the Atari 850 interface for terminal access (Perhaps Atari had in mind
a 4 user terminal system connected to the 850 interface using an Atari
800 as a host, hmmm.... the possibilities). The B&W
cable kit was to allow an Atari 800 to connect to a monocrome composite
monitor, the color lines were omitted to allow crisper output.
The Color cable kit had all the color and luminance lines available for
connecting to color color composite monitors. (Included in
both monitor kits were various connectors for the many varying monitor
connection systems before RCA became standard.) Missing from
the above picture is the SIO (Serial I/O) cable kit.
