FC Twin NES

Post by Billybb347 » Mon Mar 26, 2007 9:04 pm

My FC Twin's motherboard fell apart and I was wondering what use I can still get out of it. Has anyone used the NOAC on the FC Twin?
And If so what are all of the wirings on board for the power and outputs and controller and such.

Hmm, what do you mean by "fell apart"? That's rather vague and kinda hard to go on. :lol:

But as far as pinouts for the NOAC board go, if you could get some high-res pictures of the front and back of the board, I can most likely decipher the pinouts for you!

By fell out I mean the glue holding it together fell off and the connections followed soon after. :roll: :P

As for scanning it in I might be able to do that but no till tomorrow.
And my scanner isn't all that good so it might not pick up.

Wow, that sounds like a miserably built machine.

Because a FOAC/NOAC is a self-contained system pretty much all it needs is a power jack, a 7805 regulator, 2 RCA jacks for Video/Audio, 2 controller ports, a ~21.477 MHz crystal (for NTSC operation anyway), and a cartridge slot. Extremely simple. Rather than try to isolate those components on the board your best bet is probably to just get a breadboard and wire up the components you can harvest from the FC Twin. I wouldn't bother trying to get a fresh FOAC/NOAC, just steal the whole CPU board out of an existing Famiclone that suits you-- (look for one with good audio, most of them are pretty terrible in that regard) and wire it up to the rest of the system.

Of course at the end of the day all you'll have is an existing Famicom clone system that has a spiffier case. You may have an easier time just ripping all the guts out and putting in a whole Famiclone board set (usually 2 or 3 small PCBs-- CPU, AV and Controller.)

Scan of the Bottom.

I heard from somewhere on the forums that the first ten pins aren't used on the NES and go strait to the SNES part of the board.

EDIT: Fixed link

Epicenter I don't quite know what your tiring to say, but everything is still there and works its just the connections are bad.

Um. Have the traces come OUT OF THE BOARD? Or is that shredded ribbon cable? What the hell happened? I've never seen STRANDED leads coming off a FOAC/NES CPU board-- that's just really crap design. Anything carrying logic signals should have single solid leads for traces. That looks remarkably bad.

Seems the stranded ribbon cable was just stripped. Wasn't the pinout for this posted already somewhere?

On everything but the NES part of the FC Twin fell off ( the connections broke). The connections on the NES are striped because I tried to take them off too but just the plastics came off.
And it wasn't like I opened the case and the connections fell off it took a couple of weeks of fiddling and improper to get the connections to fall off.


Could you point me in the right direction for that diagram? I couldn't find it when I searched for it.
