Im having some overclocking problems.

Im overclocking my gameboy color, and it has a DPDT switch so I can select either the regular or oveclocked speed. It was working fine until I wired up my oscillator of 8 mHz, which is roughly the original clock speed.

I think I have it wired up correctly, but im not sure. The two contacts cirlcled in blue is where I have soldered the wires.

So, is there a certain way I need to wire that oscillator, or is it wired correctly now?

Note this is a generic oscillator, not yours.

Er, you need a crystal, not an oscillator...

those words can be used interchangably in some contexts. the same context where they can also be used together - 'crystal oscillator'

http://en.wikipedia.org/wiki/Crystal_oscillator

and thats probably a crystal oscillator

with that said, it dosent look like its the right kind of crystal. the ones im used to only have two contacts. none of this fancy 'enable' crap.

you might still be able to get it to work.

then again, i dont even know what kind of crystal is inside a gameboy.

Actually, I think that diagram is of my picture, because in the bottom right corner of mine it has that corner that is "cut off". In that case, what is 'enable' and 'supply'? My guess is that supply is power.

Heres what the listing says

Each sale is for 50 pieces of Seiko/Epson SG-8002CA-PCC 8.0000MHz 3.3V surface-mount crystal oscillators. These are/were programmable-frequency oscillators that have already been configured for 8MHz. 2001 date code. Shipped on cut tape.

0.5 ounces per 50-piece tape
4 lots per 0.3 ounce mailer

Timmeh: Im not sure what type of crystal is inside the gameboy color, but there were 6 contacts where the old crystal was.

It was only two, each soldered in three places.

This one has 3 contacts on each side of the crystal/oscillator. I dont know where my camera is now, but when I find it Ill take some pics.

I overclocked mine, there are 3 solder pads that are connected by a trace for each side. I checked because I couldn't figure out which I should solder it to, and then noticed they were connected.

Right. What I meant by contacts is each little soldering pad.

Again, does anyone know what enable and supply is on the diagram?
