SECTION 1
THEORY OF OPERATION
The Atari 130XETM is an enhanced version of the existing Atari computer systems. It can be
used with any existing Atari peripheral devices which are compatible with the 400TM/800TM
or XL series computer, although not all are necessary.
The console contains 128K of RAM and has an operating system which contains one 16k X 8
ROM. The console also contains the keyboard with a HELP key, four programmable function
keys START, SELECT, OPTION, RESET, a single Cartridge slot, an Expansion connector,
jacks for adding peripherals and hand controllers, a detachable (RF) TV interface cable and
one power LED.
Use Figures 1-1, 1-2and 1-3 as reference for the following discussion.

User Interface
The Atari XE series are a general purpose microcomputers which uses a 6502C
microprocessor. The 130XE console is the central processing unit for its respective system.
The right side panel (refer to Figure 1-1) contains two controller jacks. The controller jacks
accept the X-Y joystick and the paddle controllers available from Atari.
The rear panel (refer to Figure 2-1) contains the Serial Input/Output (SIO) jack, Cartridge slot,
the Expansion connector, the channel 2-3 switch, the RF cable jack, the Monitor jack, and the
Power Jack.
The console has a full stroke 62 key alphanumeric keyboard, which includes special
characters and controls, a space bar, and 5 function keys.
130XE Personal Computer
Field Service Manual 1-2

The 5 function keys above the keyboard are made of the same color material as cover. A
translucent plexiglass strip on left-bottom corner of top cover indicate the operation (Power
On) and covers the red LED.
From left to right the function keys are:
HELP – Gives you instruction in some programs when you need help.
START - Press to run loaded program. Frequently used to load program from cassette. Fully
programmable key
SELECT – Often used to select one of several applications within a program. Fully
programmable key.
OPTION – Allows the player to choose among the variations of a program. When this key is
pressed during Power On – internal Basic is disconnected and – if you do not
have active floppy drive – SELF TEST is running (see page 3-2). Fully programmable
key.
RESET – Interrupts and restarts the operating system or cartridge.
Mechanical Description
The 130XE computer console contains a single motherboard which houses all the chips of the
system and provides connectors for interfacing external modules to the console. It includes
the CPU, ANTIC, GTIA, POKEY, PIA, FREDDIE, RAM, ROM Operating System, and
includes all functions. The motherboard uses a common address bus, data bus and clock lines.
The sixteen-line address bus allows the microprocessor to directly address 64K of memory
locations. The eight-line data bus provides the communication and data path between the
functional modules. The various power requirements are routed from the power supply
throughout the console.
The keyboard is connected to the PC Board by a 24-conductor foil cable.
Figure 1-4 is a block diagram of the functional flow of the 130XE.

Alphanumeric Television Interface Controller (The ANTIC Display Processor
The ANTIC Display Processor is a custom display microprocessor with an instruction set
customized for graphics generation. It also has the ability to control bus and RAM REFRESH.
Figure 1-6. Display Processor Pin Assignments
130XE Personal Computer
Field Service Manual 1-6

Graphics Television Interface Adaptor (GTIA)
The GTIA interfaces with the ANTIC processor on one side and with the video summation
circuitry on the other. Its primary task is to generate color and luminance signals from the
display information bit stream it receives from the ANTIC Display Processor.
Figure 1-7. GTIA pin assignments
POT Keyboard Integrated Circuit (POKEY)
The POKEY is a Custom Large Scale Integrated Circuit (LSI) chip. It is used for audio
generation, Serial Input/Output (SIO) control, controller interface scan and keyboard scan.

130XE Personal Computer
Field Service Manual 1-8

Memory
The 130XE operating system is resident to 16k X 8 ROM. The ROM input CPU address lines
A0 through A13 and the chip selects from the MMU, generates data on CPU data lines D0
through D7. RAM is organized as 16 X 64k x 1 or 4 X 64k X 4 chips, two for each data line.
48K RAM is directly available, but more is accessible under DOS 2.5.
Memory Management Unit (MMU)
The Memory Management (Address Decoding) circuitry consists of a Programmable Array
Logic (PAL) and one 3 to 8 decoder. The input to this circuitry are the address lines A8 thru
A15 and control signals like ROM enable (from PIA) and Refresh. The outputs of this
circuitry are GTIA chip select (D0XX), Expansion selects (D1XX), POKEY chip select
(D2XX), PIA chip select (D3XX), Cartridge selects (D5XX), O.S. ROM selects and RAM
selects.
The RF Modulator
The RF Modulator inputs the composite video from the video summation circuitry and the
monoaural audio signals and produces a modulated signal suitable for the television.
The modulated signal will have the following characteristics with a 75Ωtermination:
Maximum Voltage: 2 mV
Minimum Voltage: 1 mV
Audio Sound Carrier Frequency: 5.5 MHz
Frequency Response:
Ch. 3 61.25 MHz ± 0.5
Ch. 2 55.25 MHz
Power Supply
The 130XE has a external power supply. The power supply jack, power on switch and filters
are resident on the motherboard. The power supply accepts a 5V DC input through the power
jack. An external step-down transformer accepts 115V AC or 230V AC from the power line
and steps it down to 9VAC. The 9VAC input is rectified by a bridge rectifier and then
regulated power output from the regulator.

SYSTEM INTERFACE
The 130XE provides the following interfaces:
•The Serial Input/Output (SIO) interface
•The keyboard interface
•The controller jack interface
•The cartridge interface
•The monitor interface
•The LED board interface
Serial Input/Output (SIO) Interface
The Atari 130XE communicates with peripheral devices over an asynchronous serial port
(19.2K Baud Rate Max). Data is transmitted and received as 8 bits of serial data (LSB sent
first) preceded by a logic zero start bit and succeeded by a logic one stop bit. The serial data
out is transmitted as positive logic. The serial DATA OUT line always assumes its new state
when the serial CLOCK OUT line goes high; CLOCK OUT goes low in the center of the
DATA OUT time.
The bus protocol specifies that all commands must originate from the computer, and that
peripherals present data on the bus only when commanded to do so. Every bus operation goes
to completion before another bus operation is initiated (no overlap). An error detected at any
point in the bus operation will abort the entire sequence. A bus operation consists of the
following elements:
Command Frame (From Computer)
Acknowledge Frame (From Peripheral)
Optional Data Frame (To or From Computer)
Complete Frame (From Peripheral)
