are these pcbs the same boards and are they compatible? what happens if you install a unisystem board in a red tent? and if it does work can u install another chip set on the other side? thanks!
 
They use the same PCB.

The UniSystem uses only one side (unless you have a game that has 2 sets of chips) since it only plays one game.

The DualSystem must have both sides populated with chips (for one or two games) in order for it to even run.

Ex. In my red tent, I can have a PCB populated with Vs. Balloon Fight (12 chips/2 PPUS) OR Vs. Excitebike/Vs. TKO Boxing (6 chips/1 PPU [Excitebike] + Daughtercard/1 PPU [TKO])

See www.johnsarcade.com for vs. info and videos of how the pcbs and chipsets work.

so in order to run in the red tent it has to have BOTH sides populated. i have a unisystem board(one side) but didnt want to install it without the info.so i have to locate another chipset before install right? thanks!

Exactly!

Yeah, I had a similar situation just recently where I had sold off a lot of my Vs. sets and didn't have enough of the right PPUs to get both sides running. You need 1 to 2 chipsets (depending on games) and 2 PPUs (and 2 CPU chips) to make a complete board.

So to do a more detailed equation, I had:

Vs. Excitebike Set (6 Chips + One 0003 PPU)

AND

Vs. Balloon Fight Set (12 Chips. No PPUs)

I got a TKO Boxing daughtercard (Has one 0003 PPU on it)


So now I can do the following combinations:

Vs. Balloon Fight (12 Chips + Two 0003 PPUs)

OR

Vs. Excitebike and Vs. TKO Boxing (6 Chips/One 0003 PPU + Daughtercard/One 0003 PPU)

Finding Vs. sets isn't hard as they come up all the time here on KLOV or on ebay. Though, it depends on what you're looking for specifically. If you want any game, finding a set is easy.

In my case, I was more picky with my selection since I really wanted to get the 0003 PPU for Vs. Balloon Fight. So I was restricted to looking for Excitebike (duplicate), TKO Boxing, Soccer, Goonies or Dr. Mario. The problem is almost all of these sets are sought after and pricey from $50-80 shipped (without a PCB).

Search the FS section, post in the WTB section and check ebay. That's your best bet. Good luck with the hunt!
 
BTW it won't harm your board to put it in your red tent with only one side. The screens will jump, though. Somebody said if you unplug the other monitor, it won't do that but I've never tried it.
