The Atari 130XE Personal Computer Field Service Manual is a reference guide for the service technician. Since the XE series has more models, so on the basis of the 130XE model will also be discussed different versions 65XE computers, as well as console XE-SYSTEM .
SECTION 1 THEORY OF OPERATION The Atari 130XE 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 400 /800 or XL series computer, although not all are necessary.
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.
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.

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.
• 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.

SECTION 2 SCHEMATICS AND PICTURES The schematics and silkscreens for the 130XE, originally they were attached to the cover of this manual, but due to the poor condition of copies have been redesigned and presented in this chapter. Minor variations in design may be encountered depending upon the production date of the console.
SECTION 3 TESTING OVERVIEW This section describes the procedures available for testing the 130XE. They are: • Self Test • Using Atari 65/130XE R.2 Diagnostic Cartridge EQUIPMENT NEEDED • a 130XE console with accessories a TV set, properly adjusted •...

The following are brief descriptions of each classification: FIELD CHANGE ORDER A Field Change Order describes hardware or software changes to ATARI products and instructs how to implement these changes. This identifies a failure mode which affects reliability and describes a procedure to correct the failure. This procedure must be performed on all units serviced or repaired.
