Last Action Hero
Data East, 1993What are and where can I find replacements for the caps just below cn1, cn2 and cn3 on the cpu board for a last action hero CPU board. They are pretty badly burned. They are on c131-c138. I also need c32-c39, they look the same but may be different. I also need EF6821P chip. Are these easy to find? Thanks all!

You can find the cap values in the schematic
If you could give me a little tutorial on how to read the values of c131-c138 on the MPU board beneath cn1 that would be much appreciated. Thanks for your help. I already talked to Todd and planned to buy those for 7.50 each but just having trouble finding the values of the burned caps.
C131 thru C138 and C32 thru C39 -- 470pF ceramics.
Examples -- CCA-470pF-50V or CCA-470pF-100V as found on this page:

470pF ceramic caps are pretty common, Todd most probably has them as well. If buying the 6821 there, may as well buy the 470pF caps there and save on shipping costs.
