The CX5200 Field Service Manual is Atari, Inc.'s service manual for the Atari 5200, document FD100127 Rev. 4, July 1983. The hosted scan has 180 pages with a text layer. Rev. 4 was made by engineering change notice 0036 (21 June 1983), which added the two-port model: its schematics and silkscreen, sections 3A, 4A and 5A, and new sections 6 and 8.[1]

The manual covers the three production boards: the original four-port board CA018087, the four-port "Universal" board CA020108 and the two-port board CA021374. Unless it says otherwise it describes the original four-port board. A Universal four-port console has a "+" as the third character of its serial number.[2]

Tech tips filed in the hosted copy
Number Date Subject
6 17 November 1982 Power adaptor: use the CX521 AC/DC adaptor (C018187, 9.3 V DC at 1.95 A); an adaptor from the home computers damages the adaptor and the CX5200 switchbox
7 20 January 1983 Rockwell 6502 MPUs marked RC with date code 8250 or later have a timing defect; the factory fix is an R-C network at U14A pin 1 and U6A pin 4
8 Not legible Replacing damaged controller boots
9 April 1983 Controller knob puller tool FC100214
10 8 April 1983 New fire button, C020501
12 6 June 1983 Board CA018087: blank or garbled screen from a solder bridge between the A0 address trace and the REF trace near J1

The tech tips are quoted from the scan (PDF pp. 171–180).[3] The separately hosted Atari 2600 and 5200 Field Change Orders and Tech Tips has further 5200 bulletins.

What this manual does not contain

  • Component values inside the RF modulator or the switchbox, which are listed as assemblies.
  • Any PAL console. The power-up test reports the type of GTIA fitted and treats "PAL" as a wrong chip to be replaced (p. 3-3).
  • The later tech tips and field change orders, which are in the separately hosted collection above.
