Ram Bad message

[CongoBongo]

I just build a Konami Classic to JAMMA adapter this week and it
works great (Jailbreak rocks). When I went to test my Yie Ar Kung Fu board however, nothing came on screen. I then reset all of the socketed chips and now I
get a "RAM BAD" message. Anyone have any suggestions? I don't even know what chips are the RAM.

Go get the the manual for it from KLOV at http://www.klov.com/game_detail.php?
letter=Y&game_id=10513.

It has some brief description of the 2 ram chips and diagnostics. You might have to closely scan the schematics to figure out
where they are.

Thanks, I already downloaded the manual but I'm afraid my ability to read schematics is very
limited.

Hmmm. I took a look at a picture of the board. It can't read the chips but I
would guess that there would be 2 identical ram chips that would be the same width as the rom chips (the fatter ones). There were different manufacturers so
that is not really a way to check (unless Konami stuck with one manufacturer). Another clue might be to look for the two chips and read the markings ...
look for a -80 or -60 (or -xx) at the end of the chip number. These used to denote the ms speed of RAM chips back in the 80's.

Do you have any hi
res / closeup pics of the board?

I would assume they would be soldered right to the board.

Thanks, I'll attach a pic tonight. In the case that they are soldered to the board, what can be done to fix this problem? Replacing the
RAM altogether?
