Atari 5200: Difference between revisions
Verification drive: flag unverified component data pending check against a primary source |
Verification drive: rebuilt against Atari's CX5200 Field Service Manual, the 5200 schematics and the 2600/5200 Field Change Orders. Corrected the power supply (CX521 P/N C018187, 9.3 V DC at 1.95 A, not 9.3 V AC at 3.5 A), removed all PAL claims (the 5200 was NTSC-only), removed the fabricated chip-register and controller-pinout tables and the IC-count table, added sourced designator maps for all three boards, the cartridge +5 V jumper, Atari's diagnostic voltages and the Rockwell 6502 field... |

The Atari 5200 SuperSystem is a home video game console released by Atari, Inc. in November 1982. It uses the same custom chipset as the Atari 8-bit computer line — ANTIC, GTIA and POKEY around a 6502 — in a console package. It was sold in North America only; there was never a PAL Atari 5200.
This page concentrates on the information a repairer needs. Atari's CX5200 Field Service Manual is the primary source for almost everything below.[1]
The three PC boards
Atari shipped three different main boards, and they are not interchangeable for service purposes — the designator prefix itself changes between them.[1]
| Board | Ports | Designators | Identification | Notes |
|---|---|---|---|---|
| CA018087 (original 4-port) | 4 | U1–U29 | — | Needs retrofit kit CA023019 to work with the CX55 VCS cartridge adaptor |
| CA020108 (4-port "Universal") | 4 | A1–A28 | Serial number on the base has a + as its third character | U4 and U15 (74LS244) deleted; U14 and U28 replaced by a 74LS125 at A14 and a 74LS51 at A15; provisional circuitry for the VCS cartridge adaptor added |
| CA021374 (2-port) | 2 | A1–A28 | Two controller ports | As the Universal board, plus: ports 3 and 4 and their discrete components removed; A12 and A13 removed; manual switchbox instead of the automatic one; the power adaptor plugs into the console instead of the switchbox |
Atari's serial-number identification for the Universal board is a plus sign as the third character, for example "AT+213…".[1] Collectors usually call this the "asterisk" board.
Integrated circuits
| Function | Device | CA018087 | CA020108 / CA021374 |
|---|---|---|---|
| Microprocessor | Atari C014806 (6502 variant) | U2 | A2 |
| Display list processor | ANTIC, Atari C012296 | U3 | A3 |
| Graphics | GTIA, Atari C014805 | U5 | A5 |
| Sound, pots, keypad scan | POKEY, Atari C012294 | U7 | A7 |
| System ROM | Atari C019156 (4096 × 8) | U8 | A8 |
| Reset and video buffer | 4050 | U1 | A1 |
| Address decode | 74LS139 | U6 | A6 |
| Keypad multiplexers | 4052 | U9–U13 | A9–A13 (A12, A13 absent on the 2-port) |
| DRAM address multiplexers | 74LS258 | U16, U17 | A16, A17 |

The 6502, ANTIC, GTIA, POKEY and ROM identifications come from Atari's parts lists and the console schematic;[1][2] the remaining functional descriptions are from the Console5 TechWiki, a secondary source.[3]
The 5200 schematic marks the RAM as MB8118-12 with the note "typical 8 chips"; Console5 lists the equivalent 4516. Either way these are 16 K × 1 dynamic RAMs, eight of them, giving 16 KB.[2][3]
Power
This is where the 4-port and 2-port machines genuinely differ, and where most surviving 5200s fail.
4-port: power through the switchbox
The original and Universal 4-port consoles have no power connector of their own. Power and RF share one cable to the CX522 switchbox, which also contains a relay that switches the television between aerial and console.
- Power pack: CX521 AC/DC Power Adaptor, Atari P/N C018187. Output: 9.3 volts DC at 1.95 A.[4] It is a linear supply: transformer, bridge rectifier, a 3300 µF/25 V reservoir and an MDL-5 fuse, all inside the brick.[2]
- Atari's tech tip warns explicitly: do not use an HCD power adaptor with the CX5200 — it will damage both the adaptor and the switchbox.[4]
- The switchbox select switch has two positions: NORMAL, which lets the console switch the television automatically when the power switch is pressed, and STANDBY, which allows television viewing while the console is on.[1]
2-port
The 2-port console takes its own adaptor (Atari A.C. adaptor assembly CA021673) directly into the rear of the case, and uses a conventional manual switchbox.[1]
Inside the console
Regulation is by two +5 V regulators, VR1 and VR2, on a heatsink assembly (Atari CA019069). Atari's parts list gives the device as a 78M05 (C014348, the 500 mA part, the same regulator used in the Atari 2600); the slightly earlier schematic prints LM340T-5. Each regulator works with an MJE-210 power transistor, and a +9 V rail is taken from the unregulated supply as well as the two +5 V rails.[1][2]
Expected readings, from Atari's diagnostic flow charts:[1]
| Test point | Expected | If wrong |
|---|---|---|
| Core of J3 (power/RF input) | 10–12 V DC | RF cable, switchbox or power pack |
| Input of VR2 | +12 V | |
| Output of VR2 (pin 3) | +5 V | Check for a short on the output |
| Pin 13 of U29 (A26), the 4013 latch | Toggles between 13 V and 0 V when the power switch S2 is pressed | Power latch fault |
| Pin 3 of the RF module | +5 V | L13, the RF module, or an open to VCC2 |
The cartridge carries the +5 V jumper
The console's +5 V distribution is jumpered through the cartridge: the schematic marks a link between J1 pins 36 and 18 as "jumper in plug-in ROM cartridge".[2] A 5200 with no cartridge in the slot is therefore not fully powered. This is designed behaviour, not a fault, and it is worth knowing before you start probing a "dead" console with an empty slot.
Capacitors
The 5200 has remarkably few aluminium electrolytics — essentially one, and its value depends on the board:[1][3]
| Ref | CA018087 (original 4-port) | CA020108 and CA021374 | Type |
|---|---|---|---|
| C45 | 4700 µF 25 V (Atari C016033) | 47 µF 25 V (Atari C020121) | Electrolytic, radial |
| C41, C42, C119, C144 | 10 µF 20 V | 10 µF 20 V | Tantalum, axial |
| C13, C14 | 820 pF 25 V | 820 pF 25 V | Polystyrene, audio circuit (Atari C018621) |
| C43, C44 | 0.22 µF 100 V | 0.22 µF 100 V | Polyester, radial |
| C19, C99–C106 | 0.047 µF 100 V | 0.047 µF 100 V | Polyester, radial |
Everything else on the board is a ceramic axial. The big 4700 µF at C45 on the original 4-port board is there because that board's supply comes through the switchbox cable; the later boards, which take a shorter or separate supply path, use only 47 µF in the same position.
Controllers
The CX52 controller (Atari CA018107, used on all models) has an analogue joystick, a 12-key keypad, two fire buttons on each side and three select buttons.[1] The keypad, fire buttons and select buttons all run through a single flex circuit, which is the controller's main wear item.
On the console side, the keypad matrix is scanned through five (or three, on the 2-port) 4052 analogue multiplexers, with a 470 Ω series resistor and a 470 pF capacitor on each port line.[2] A controller fault that affects one port only is usually the flex circuit or the port's 4052; a fault affecting all ports points at POKEY.
Atari's potentiometer adjustment procedure gives real numbers to work to:[1]
- With the arm off the wiper shaft, adjust the shaft so that the reading between pot terminals 2 and 3 is 5 kΩ–20 kΩ.
- Fit the arm in the documented position and reassemble.
- With the joystick at position 1, the reading through the cable (connector pins 11 and 9, and pins 10 and 9) should be no greater than 50 kΩ.
- At position 2 the reading should be at least about 100 kΩ greater than at position 1.
- If the test fails, replace the pots; if the pots have already been replaced, replace the actuator plates, which must be replaced as a complete unit with the slide block.
The non-centring design uses a rubber boot rather than springs. Atari published a boot replacement procedure and a knob puller tool (FC100214) because the knob is difficult to remove without one.[4]
Known factory faults
- Rockwell 6502 MPUs with date code 8250 and later (stamped with the letters RC) have a timing defect. Atari's factory modification adds an R–C network on the component side of the board at U14A pin 1 and U6A pin 4. The network does not need to be removed to use another manufacturer's MPU or a Rockwell part with a different date code.[4]
- CX55 VCS cartridge adaptor compatibility. Original CA018087 boards need retrofit kit CA023019, which solders wires to pins 24, 30 and 11 of J1. Atari's procedure carries an explicit warning: if the red jumper wire is grounded, the 5200 power adaptor will burn out.[4]
Cartridge slot
The cartridge socket J1 has at least 36 positions; the +5 V jumper occupies pins 18 and 36.[2]
