SECTION

THEORY

OPERATION

There are currently four types of ATARI Video Computer Systems. The original model

(2600) is composed of two

Boards connected by a 12-pin ribbon cable with the

motherboard surrounded by a heavy aluminum casting.

The

other models (2600A: Revisions 1-13, Revisions 14-15, and Revisions 16

and up)

are composed of a single board with

light aluminum shield. The single board models

differ slightly in the video output circuitry. Component differences are:

Revisions 1-1

have no diodes on TIA lines LA41 and Sync.

Revisions 14-15 have diodes and pull-up resistors on TIA lines LMl

and

Sync.

Revisions 16

and

up include the above mentioned diodes and resistors

well as

timer chip.

The revision level

etched directly on the

board.

OVERVIEW

The ATARI Video Computer System (VCS) Models 2600/2600A are state-of-the-art

microcomputers. They receive instructions for the operation of different games from

individual Read-Only-Memory game cartridges and interpret data from the players'

hand-held controllers. They

also

allow game players to select both a specific version

each

game and the player difficulty (on a per player basis). Figure
