Not sure if this is the correct location as there aren't a lot of wanted ads here. If it should go in a different section please let me know.
I know a few people here have RGB modded their NES with PPU's from Playchoice PCBs. I was wondering if anyone had a Playchoice PCB leftover without the PPU for sale? I'm looking for the Single Monitor Version Playchoice PCB. The Single Monitor Version has 2 edge connectors on the PCB. If you have one you'd like to get rid of send me a PM please. Don't need the CPU either if that is an issue as well.
I have a .Vs board hanging around. I think it was for Duck Hunt. I know, not much help. But yes, it's missing the PPU (the one for RGB modding).
Probably not helpful to you, but I figured I'd throw that out there.

Thanks for the offer. I have a few of those and would like a single monitor playchoice pcb to go in my cab as well.
as I stated in pm. I recently bought a dual moniter pcb (still waiting for it to arrive). I'd be more than happy to sell it to a collector who'd play it in a cab. I'd even be willing to solder a 40 pin ic socket onto where the ppu goes. However if you're only interested in the single moniter version all I can do is with you the best of luck.
Doesn't the VS PPU have a completely different palette than the regular PPU?

Yeah, they do. In fact, they differ from each-other, as I recall, so that game vendors couldn't burn new ROMs to upodate cabinets when a new game came out.
That is, Vs. SMB has a different colour palatte to Vs. Ie Climber and the like. There may be a Vs. game that shares the colour palatte with the NES PPU, however I am unsure about this.

Vs. Duck Hunt uses a palette very close to the NES one. I guess requiring Zapper light guns was enough copy protection.
Yeah, I've heard the Duck Hunt PPU is the normal palette. I'd also heard that VS RBI Baseball has several palette tables in it (for different PPUs), so it served as sort of a Rosetta Stone for mapping out the differences.

according to this tennis uses the same ppu as duck hunt. Unless tennis uses a custom controller I don't think your theory applies

I'd bet the control panel is wired differently when the gun is installed, I'm not sure though. You definitely couldn't have a lightgun and 2 controllers at the same time, at least not using the "usual" way that the NES system uses.
The Duck Hunt kit obviously had to include a wiring harness of some type for the gun.
hey 2600 I found one on ebay for you
Extra WIIIIIDE URL [please use the [url=] syntax next time to avoid widening the page -- MOD]
if you're outside of the US try contacting the seller and seeing if he/she would be willing to ship outside of the states
however like most pc pcbs I come across it's listed as "untested" so you'd be taking a slight risk
Thanks. I already have one, but was hoping to pick up a backup main board for a bit cheaper although I may bid on that one. I was hoping to find someone with a PCB they robbed the PPU from. I've got a load of PPUs and don't really need that part. BTW, the PPU is already socketed so no need to solder in a socket.
EDIT: Just looked at the EBAY ad again. It is a Dual Monitor Board not a Single Monitor Board.
For those wondering about the gun and Duck Hunt, IIRC, the gun takes the position of player 2. I believe there is also a check on another bit that detects if the gun is there. If it is not, the Vs. games makes an annoying "alarm" sound. There is what I will call a rumor that Vs. Duck Hunt also comes in a different version that uses a different PPU, but I haven't seen proof of that yet.
Vs. Tennis requires 2 PPUs. The Vs board has basically 2 NES systems on it and Vs. Tennis requires both NES systems to run.

Hmm... Actually, I've seen that before: The Famicombox, which is based on the NES hardware, has two controllers and the Zapper wired at one time.
Somehow I figure that Tennis
was its own copy-protection.
I thought that Vs. Duck Hunt was in the lot of PPUs that can be used in the NES with minimum colour shifting, but I wasn't certain... Good to know that Tennis is as well, as it's probably a very cheap board.

ahh I didn't know the playchoice is socketed. Just so you know this "auction" doesn't have "bidding". It's simply buy it now or best offer
sorry mods about the long url I don't post on forums very often
oh wow I'm an idiot, it's clearly a dual moniter. Guess I figured they'd say so in the auction. But now that I actually looked at the board it only has one edge connector

Would it be possible to bridge both monitor signals into one wiring harness to connect to one CRT from a dual-monitor board?
There is a great PC-10 system loaded with games on ebay now for $300... I'd love to buy it, but it is local pickup only in Indiana.

If you'd want to get expansion sound entierely with the bottom connector (without any special hardware on the cart), you'd need to acess sound registers through a serial protocol via $4016 and $4017. That'd be perfectly possible, but you'd need to implement it yourself in your favourite open source emulators, and only games that were made to use this will use it.
I don't think it's possible to make the bottom connector respond to other register writes, or doing so will require a modified cartridge that re-route some adress/data lines to the general purpose expansion pins, and if you're doing that you might as well add audio hardware on cartridge and use the expansion connector just as a bridge to get audio working.

Yes, you could use a 4P relay to do that. The single monitor board switches between both signals on the PCB.

But since the data bus is on the expansion, the only thing a cart needs to send to it is a single chip enable output. Pretty easy to do on a new board (if you don't like the $4016/$4017 stuff).
That's way cheaper per cart than adding the audio hardware. Even if one pulled of some super cheap audio stuff for $5 total, that's not going to add $5 to the selling price, it would add more like $10-$15. So that can knock a huge amount of the selling price per game, paying for itself if enough games used it (and used it well).
Xious: That PC10 cabinet is only 2 hours from me. I am really damn tempted to go get it!

if both moniters use the same type of signal (I assume they do) then you could install a switch that selects which rgb s/g signal is going to the screen. It would be a little odd hitting a switch to go between the game screen/choice screen but it would work. Another option I've seen a lot of is people just use a small lcd screen for the secondary screen. Or you could do what 2600 suggests. I'm still waiting for the hardware to arrive in the mail and I've never actually seen how it works which's why the only option coming to my head is a manual switch.

I doubt it will sell for that much. You should be able to get that for $200-$250 at most if you want to do a best offer. BTW, that is the single monitor version and you should be able to swap in a Vs board with little to no effort.
Well,
I got it.
I didn't make a really low offer though, just enough to make up a little for some fuel costs.
From what I looked up quickly earlier today, the controls are wired differently for the VS, but that's no big deal I think.

that's a great fix me up cab and for an even greater price
For those suggesting to use a dual monitor PCB on a single monitor cab. Just rewire the single edge connector pins to the female dual harness of the single cab, and swap the bios at 8T with a single monitor bios. The rest is the same.
Edit:
Thinking about it more, the bios sizes are different...it may be okay to go dual to single, but maybe not from single to dual... i should try with one of my cabs
well I got a dual screen playchoice pcb. Took the ppu off, it's up for sale without the ppu if anyone's interested
