NES On A Chip: 72-Pin Connectivity

Mike · Post by **Mike** » Mon Mar 23, 2009 2:50 pm

Greetings team.

Unfortunately there is not a great deal of organized information regarding NES-On-A-Chips, otherwise known as NOACs.

One branch of my research involves the possibility of removing the broken innards of an old NES, and replacing it with an NOAC.

However, I desire that said chip reads old cartridges, and not a miniature harddrive or something of it's ilk.

What information can you share with me regarding the subject?

Thanks,

Mike, possibly a legend

Not 100% sure what you're trying to do here. Also nesses rarely break 99% of the time its the pin connector.

I would go as far as to say if your NES really has a broken motherboard and the pin connectors aren't the problem you should just go on ebay and get another real NES with a new cartridge connector. NOAC's are not 100% accurate. I don't think I'd ever use one.

That's probably because they suck. They output wrong colors, wrong audio and fail to work with complex mappers such as the MMC5. Are you sure you want to use one of those?

There are clone systems with NES cart slots, though not as common as Famicom slots.

Most NOACs are glop-tops, probably not too fun to wire directly up to. There are NOACs in normal packaging, but it'd be hard to find any place selling just 1 or 2 of them.

You'd probably find more and better info from people who've built portable NES's using an NOAC. If you want to wire up something that looks similar to these, that's what you're in for.

That's probably because they suck.

Actually, some of the clones are better than the others. I know I've heard of at least one of the clones having the pinout wrong and messing up MMC5 carts, but I think that could be a problem with the PCB layout.

Hmm... Would you kindly give me a couple of examples of NOACs? I cannot form knowledge based on opinion.. Gotta see the numbers!

Yobo, retro duo, powerjoy. But really they all suck.

Okay. So the most reliable choice as of the present date in regards to playing NES games via hardware, would be an actual NES. That works out well!

Okay, this is doable. Merely a sidetopic to my main research line.

Thanks kindly!

Mike, nom nom'ing on some tasty chef boyardee

I find the best way to acquire 'em seems to be through word of mouth.

I've got a lot of friends who, being 80's kids like myself, all have either NES, SNES, or Genesis's to donate to The Cause. Really, I only need NES's, but it wouldn't hurt to learn to do the same for SNES.

Life is great!

I was planning on getting NOACs as a method of making a system or three for friends who don't have them, and want to play these challenge level gamesets as well.

On a side note, I totally got signed up to do kareoke tonight after work. Some Miley Cyrus song? Never heard it before, but I totally rocked the joint with it.

-Mike, rocks it all

not always a fortune. But I do see what you mean! Alot of them are more than $100. I got my second one at a garage sale.

Probably needs new cartridge connector

Ebay is an auction site, so stuff is priced based on what the dumbest rich person will pay for it.

Try not to bid more than $30 for one (and if shipping is over $10-12 take the difference off the price you're willing to pay). And eventually, after a few dozen attempts you'll get one. You can get them for $40 fully refurbished through several online game sites, so never pay more than $40 for one on ebay (average price is $60). It can get a little trickier when they are bundled with games, I would just ignore the games unless there is a game that you also want or you are willing to turn around and sell those games to cover the amount over $30 you probably paid for a bundle.

Craigslist and local classified ads will be more reliable than garage sales, and nearly as cheap.

You can get NES' and parts very cheaply at Goodwill.

Don't bother with the Salivating Army, they have nothing but crappy clothes and old bibles
