Step 6Let's go over the circuit...
The circuit we're going to use is made of reasonably standard components, so you should have no problem getting what you need from your local electronics supplier (in Vancouver, I highly recommend RP Electronics) You could probably get this stuff at the CrapShack, but you may have trouble finding 150ohm resistors. Everything else will be there, but will be overpriced.
Anyway, as for the capacitors, the negative side should go towards the VGA connector. All of the pins on the VGA connector marked with a black dot must be grounded. The ones with white dots are unused.
By the way, if you want to add an audio jack, just use pins 2 and 3 and wire that to the right and left terminals on the jack. Ground the ground pin on the jack. I can't tell you, by the way, which one's left and which one's right, so you have a 50/50 chance of getting it right. My stereo's messed, so I can't tell you whether I picked the right one.
Do yourself a favour and don't try to solder on the top of the board. Flip it over, and you'll see some solder dots that are spaced further apart. (It's like Sega made the Dreamcast easy to hack on purpose)
The pinouts and their corresponding numbers are the same on both diagrams.

The connector schematics are very useful.
