What the hells up with the 72 pin connector?

ShaolinDrunkard · Post by **ShaolinDrunkard** » Tue Apr 19, 2005 3:51 pm

I just got a 72 pin connector to wire up to my megajoy 2. After actually seeing this thing i am more confused than ever. Please dont refer me to gannons pinout diagram beacause that is of no help to me.

Question: how do i know which pin is no.1 on both the 72 pin connector and the 60 pin famicom connector of my mega joy. Without knowing what each pins number is, a numbered diagram does nothing for me.

Also, what happened to all the people working on a more visual explaination of this?

Your help would be greatly appreciated.

Again also, plaese dont reply with some post full of electrical jargen as i am not that experienced in these matters.

Thanks

Look at the circuit board that holds the 60 pin connector, it should have a small 1 on it, the pin next to it is 1. On the 72 pin, it doesn't matter, as long as it's one of the edge pins and you continue wireing based on that being pin 1.

A lot of megajoys and superjoys do not have labeled motherboards, not even a "1" on the first pin. It's a real pain in the ass, but that's the kind of quality pirate stuff usually is. The best thing to do is to find the ground and +5v pins and match them with you Famicom side pinout. Another thing to look for is the fact that pins 45-46 are joined by a trace on the NOAC. These points should give you a bearing.

Mine does not have a 1 anywhere on it, but heres a picture of it. Im not sure how to find that tracer you speak of but maybe you can tell from the picture. Sorry bout the quality, i had to scan it.

Thanks again for the help.

The yellow circle shows pin one for a famicom cart.

Thanks a whole hell of a lot. So let me make sure i understand correctly, the pin directly to the right of the #1 pin in the picture is pin #30.

Thanks again NesMan

Sorry I meant to say pin# 31

If Nes Man was correct about that being pin 1, then yes that would be pin 31.

Cool, I hope he was correct.

Where the Red circle is, there should be a number 1. Look at the board, The number 1 is conected to pin one. The pic is to blurry to make it out. (Some people might be thinking "how the heck to you know?" Well I have a Mega Joy 2

).
