Digital SoundBoard

Les Digital Sound Board 1 et 2 sont des périphériques [MIDI] destinés à la lecture des musiques de fond sur plusieurs jeux [SEGA]. Les sons sont stockés dans des maskrom propre à chaque jeu. On les trouve sur les jeux suivants:

Première version (DSB1):

• Scud Race/Super GT (Model 3 Step 1.5)
• Sega Touring Cars (Model 2C CRX)
• Star Wars Arcade (Model 1)

Second version (DSB2):

• Daytona 2
• Lost World Special
• Sega Rally 2
• Spikeout
• Spikeout FE
• Star Wars Trilogy
• Top Skater

I get asked many questions about arcade hardware but nothing seams to be less understood then the Digital Sound Board 2. So in this post, I will explain a bit of what I know about the DSB2 boards.

First of all, this board is ONLY used in the following games:

Top Skater (Sega Model 2 game) Sega Rally 2 Daytona 2 Star Wars Trilogy Spikeout Digital Battle Online Spikeout Final Edition (Slightly patched version of the above) Lost World Special (Full scale attraction version of the game)

As you can see, other then Top Skater, all of the games that need this board are Sega Model 3 games. Keep in mind, if you try to run one of these games without a DSB2, it will work perfectly fine, it will just not have background music, only sound effects. Another thing to know is, a DSB2 board is 100% universal and will work with any listed game, the only thing you must have done is installed the proper sound roms for the game you are working it with. I have received many DSB2 boards, One had Sega Rally 2 roms in it and the other had Star Wars Trilogy roms in it. I got my trusted rom burner guy to make me some Spikeout Digital Battle Online sound roms that I needed.

The Next thing to talk about is the confusion about caged vs uncaged DSB2 boards. The pcb is a fairly small board (as seen below) with multiple sockets for sound roms and many headers for I/O. Some people tend to run the pcb as just a bare board mounted inside their arcade cabinet with pcb feet. While the boards often came from Sega in a small metal cage similar to many of Sega's boards at the time. These cages not only protected the DSB2 but also made it easier to mount or stack if the board was used outside a cabinet. The biggest problem with the filter board on the DSB2 cage is that it reverses the pin headers on most of the inputs. So if you have a 6 pin header where pin 1 on the board was +5, if you have this DSB2 is in a cage, that +5 is now on pin 6 of that input on the filter board.
