Bracket end of the 3DO Blaster CT6110: the cluster of small electrolytics beside the CD audio connectors, C36, C40 and C45 below the feature connector, and the blue C180 below the Brooktree Bt121

The Creative 3DO Blaster card (model CT6110) carries roughly two dozen small radial electrolytic capacitors: about half of them in a cluster at the bracket end round the audio and video circuits, and the rest spread over the board.[1] Creative's user's guide gives no component values, and Console5's TechWiki has no list for the card.[2][3] The card has no power supply of its own; it runs from the PC's ISA slot.[4] Its capacitors all sit on the PC's low-voltage supply rails.

Before you start

[edit | edit source]
  1. Follow Creative's order for removing the card: touch the PC's metal case to discharge static, switch off the PC and every peripheral, unplug the mains lead, then open the case and lift the card out by its bracket and edges.[2]
  2. Write down every jumper setting before touching the card. Only JP5, the base I/O address, is meant to be changed by the user; the others are set at the factory.[2]
  3. Look over the board under a magnifier for leaked electrolyte, and for lifted or cracked joints on the connectors. A card restored by The Retro Collective in 2026 worked only with weight on one corner until pins that had come away from the board were repaired.[5]

Where the capacitors are

[edit | edit source]

In archive3do's photographs of a CT6110 the electrolytics fall into these groups:[1]

  • About a dozen small black-sleeved parts at the bracket end, round the two CD audio connectors (CD audio in from the drive, CD audio out to the Sound Blaster) and beside the D-sub sockets, with several three-lead TO-92 parts among them.
  • C36, C40 and C45 below the 26-pin feature connector header, and C126 beside the CD audio connector.
  • Two blue-sleeved parts near the Brooktree Bt121 (U65): C182 beside the BLK_SEL jumper and C180 below the chip.
  • C21 beside the CD-ROM interface header, and C61 and C63 in the middle of the card, either side of the 50 MHz crystal X1.
  • C129 and C130, beside the coin cell at the far end of the card, and a few parts near the DRAM and the ARM processor whose numbers cannot be read in the photographs.

The cell itself is a tabbed coin cell in a yellow sleeve; it keeps the 32 KB save SRAM and is covered on the Creative 3DO Blaster General Maintenance page.[1][2] The connectors named above are identified from Creative's description of the card's internal connectors.[2]

None of the values can be read in the published photographs, so they have to be recorded from the card itself.

Recording the card

[edit | edit source]
  1. Photograph both sides of the card in good light, then each group of capacitors close up and at an angle, so the printing on the sleeves can be read.
  2. For each electrolytic, write down the designator beside it, the capacitance, voltage rating, diameter, height and temperature rating, and which side the stripe faces. Note any part marked NP or BP, which is non-polarised.
  3. Keep the list with the card. No published list exists to check it against.

Procedure

[edit | edit source]
  1. Lay the card on an anti-static mat. Keep the gold ISA edge fingers clean and away from flux.
  2. Replace the capacitors one at a time, so that the polarity of each can be checked against its neighbour and against your photograph.
  3. Use the minimum heat needed. The board is dense with surface-mount parts and fine-pitch chips close to some of the capacitors.
  4. Fit parts of the same capacitance and at least the same voltage rating, with the same diameter and no greater height where the card sits next to another in the PC.
  5. Clean flux off with isopropyl alcohol, check the joints under a magnifier, and refit the card with the jumpers as you found them.[2]

After the recap

[edit | edit source]

Refit the cables in Creative's order: the CD-ROM data cable and the drive's CD audio lead to the card, the card's CD audio out to the Sound Blaster, the feature connector cable and the VGA loopback cable, each with the coloured wire to pin 1 where the connector has one.[2] Start Windows, run 3DO Player and load a game disc, then an audio CD. Sound comes through the Sound Blaster, so a recapped card with no CD audio may simply have an audio cable left off.[2] Faults that remain are covered in the Creative 3DO Blaster Troubleshooting Guide.
