I was sent this link today, http://forums.arcade-museum.com/showthread.php?t=251095

Larrylemming, over at the arcade-museum.com forum, has pledged to make this happen.

I can only hope he actually makes it happen.

Wouldn't it be great to get rgb from an nes with OUT having to brick a pc10 board?

It would be even better if the replacement ppu cost anywhere under $100...

    I hope so!! The only thing is that he said it would cost more?? Really??

    $100 per a chip? Chinese PPU and CPU clones (UMC something) are still available to buy at some places, they are much cheaper, and it is possible to replace the original chips with them. I also know that few people here built a Famiclone from scratch using these two chips and few common chips like 74xx logic and RAM, with cost of all parts way under $100 as well. Here is a pic of one of such projects.



    Edit: OK, I missed the point that it is about RGB. Well, I wonder if the quality improvement really costs that much.

    interesting, hope he can drive price down



    edit: If I'm not mistaken aren't the arcade PPU's palettes slightly off from the original NES

    Yes the palette is off, but he states that his ppu will have switchable palettes so it can be put into different systems: pc10 and vs. Hopefully he will add the home console palette as well.

    It sounds like he will work on the NES palette as well. There are also 9 (or 10 if you count RC2C03C) arcade PPU versions between the PC10 and VS. I'd be curious to see if he can look at the Famicom Titler and Sharp RGB TV to see if there are any differences in those PPUs as well.

    Hey everyone.



    Sorry for the confusion about the price. I actually stated that my "replacement will be the same cost, if not higher, than the market value of the original chip". Not sure where this idea that the chip costs $100 came from (unless you're buying a whole PC10, in which case it might be)... I would value it closer to $40-$50, and I expect my price to stay south of $100.

    If someone would offer a RGB Nes with Stereo Mod service I would gladly sign up :-)

    I hope you are really serious about this project Larry. Because this will be groundbreaking!

    I still think that pushing some chinese company to produce cheap knock-offs of playchoice RGB PPUs will be a better and more elegant solution, but that is only my imagination... (Is the playchoice PPU documented well enough to be reproduced with the right equipment?)

    I will be waiting for this to come out, and try my best to be in the first line to getting one :-)
  • takeshitakeshi
    jpx72: theres still the issue with the PC10 ppus having differing palettes, you'd still need that corrected

    So there had been a few comments on the universalppu.com pages asking about fit so I posted a comment about how there was no way the pcb shown could fit the av fami, us top loader, fami, and prolly not the front loader. It wasn't really a negative comment just facts and the guy decided not to let my post go up! Why?

    He gives the size of the pcb and I simply took out those console and measured and found that the pcb will hit the cart connector on the av fami and us top loader, the reset switch on the fami and prolly the eject mechanism, and the shielding and maybe case on the us front loader.

    Then I said it was still a great project and I want to see it come to fruition.

    I understand it's still in prototype stages and that's why I posted, maybe he didn't have the consoles around to check fitment and I offered a little info, just trying to help.

    Just makes me a little uneasy when such info in squelched...

    Some people don't like criticism, at least the project isn't dead. It is only his first revision of the board as well.

    I won't be surprised if a working prototype ends up requiring its own case. That's a motherlode of traces to route; maybe once he gets it working he'll figure out how to split it into a couple boards that can be strategically places and connected to one another. Remember Benheck's Atari portable? He redid it and made it smaller and much lighter. I don't think pointing out size constraints is bad at all, so I too am surprised he didn't allow the comment to post. But I'm guessing if he gets it working, he'll work on making it efficient later.



    That reminds me... I wonder what's up with Bunnyboy's HDMI NES.
  • low_budgetlow_budget
    Looks like the Universal PPU project will only fit the arcade boards and the NES front loader maybe. I'm sure he's working on the compatibility, he's only at the hand built prototype phase at this point.

    It should be possible to reduce the overall size slightly and maybe redo the layout slightly to make it compatible.



    Hope the final version is compatible with the NES Super 8!



    Not sure, but it seems the HDMI NES project is dead, or at least dormant. Haven't heard or seen any news lately. I was really looking forward to that.
