Atari's own field service manual for the '''[[Atari 5200]]''', document FD100127 Rev. 4, July 1983. Section 1 sets out the three production boards — CA018087 (original 4-port), CA020108 (4-port Universal) and CA021374 (2-port) — and exactly how they differ, including how to identify a Universal board from the serial number. Section 2 carries the silkscreens and schematics, Sections 3/3A and 4/4A the test procedures and diagnostic flow charts with expected voltages, Section 6 the CX52 controller with flex-circuit continuity tables and potentiometer adjustment figures, and '''Section 8 the parts lists for all three boards''' with designators, values and Atari part numbers.

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]
