So I bought a used "old" chip that was re-burnt to be a 6f speed chip for ms pacman off eBay, and when I installed it I didn't get any boot sequence, all I got was what looked like a 1" orange ball with a little blue and yellow on it on the screen. Nothing else. The red reset button on the board was unresponsive as was the test switch. Yes it was in correct and in the correct spot. I contacted the seller, he sent another and I have the same issue with the second chip. I have a factory board not a bootleg so I think I can rule that out as an issue. Any ideas?? He's got good feedback and sells these allot.
the chip is no good.
it works without it , then you plug it in.. and it don't work.
all you can do is contact the seller and ask if that was a known issue with HIS chips.
