Hey all - I'm working on my Track & Field board, and I have a few questions.
1) Is this a "normal" T&F board (see pics)? It doesn't match pictures I've seen online. No board number/Konami text, no little power cable between boards. - Found a similar board sold on eBay. My board does not match the Konami schematics from the manual. This is probably a Centuri version?
4) The crowd/scoreboard graphics are scrambled, though the characters and track look OK. I assume this is a bad ROM. Can someone point me to a map of which ROMs may hold that data? (This is just to save time pulling and verifying...
) I'm not sure how to correlate the ROMs in the set to the ones on my board. Any suggestions?
Thanks for any help!
Resolved:
[Apparently the cap that popped was old. I replaced it with a different one, and sounds are working OK now, and the amp is not getting hot. This board is mono only, too...]
2) Does anyone have a source for a heatsink? Mine doesn't have one, and it's getting quite warm.
3) I powered it on, and the sound seemed to work, though it was quite low, and the volume pot doesn't seem to change it much. I ran the board for a few minutes in attract mode, and one of the electrolytic caps in the audio section popped and began to leak. Could this be a symptom of not having the heatsink?
