I just received some chips for my TMNT Turtles in Time Jamma board, but I'm not sure which chip goes where. The instructions specify to "Remove and replace the ROM's at locations J15, K15, K17, I17." But I can't find the locations on the board. There are 5 socketed chips on the board, but they're labeled B01, A04, A02, A05, and A03 (all also labeled 063). Two of the new chips are shorter than the other ones, but the pic in the manual seems to indicate that the shorter chips can be used in the left-most 2 sockets, but one could also fit in the right-most socket perfectly.
I would try just putting the chips in and seeing what happens, but this wasn't a cheap PCB, and I'd rather not damage it.
PS: Manual is here, (http://www.arcade-museum.com/manuals-videogames/T/TurtlesInTime.pdf) in case I overlooked something.

Look along the edges of the board. One edge will have letters, one will have numbers. The chip location is at the intersection of the letter and number (remember plotting graphs in grad 4 math class?)
It's also possible you have a bootleg, in which case the board might not be marked the same (and hell, who knows if those ROMs will work)

board should look like this:

using the image the way its orientated now, I'd guess the ROMs are the 4 with the white stickers grouped together on them just below the chip to the left of the konami logo

Wow, I've never seen the Turtles In Time marquee before.
...Someone at Konami should be shot for that.

I don't see any numbers or letters, looking at the surfaces (component and solder side) of the board near the edge, nor looking directly at the edge itself. In fact, I can't find it on any of my 3 other Jamma boards either (Xmen, TMNT1, and Simpsons. All Konami). Am I just overlooking these numbers and letters somewhere and be kicking myself later?
Tried the most logical arrangements of chips, but it only produced a blinking screen. The board still works OK with the original chips, though, so I didn't ruin anything yet.

Alright, on a hunch, I figured out the problem. The chips aren't for the Turtles in Time game. They're for the first TMNT game. K17, I17, J15, and K15 match up perfectly with the socket names on the board. Weird, as the auction (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200425751254&ssPageName=STRK:MEWNX:IT) lists it for TMNT2, and even the instructions mention holding in the test switch (the first game uses Dip switches only.)
I'm not mad. I was looking for the 2P chips for this game as well. It is the UK version (Hero Turtles), but I can live with that. In fact, is there even a US 2P version of the first game? I don't see one listed in MAME (I use the Oceania version on MAME most of the time on my cab.) And even though it says "Hero Turtles" on the screen, the song is still "Ninja Turtles." I though changing the ROMs changed the theme song?
I'm still interested in this whole "PCB grid location" thing that RayB was talking about, for future reference.
