Quoted from CryptKeeperAUS:Has anyone has any ghosting issues with thier machine? I have found data east to be fairly good. Also wondering if anyone has a definitive LED list? Comet doesn't have a Simpsons kit. Cheers.
I have 13 Data East pins with Comet regular LED, no problems ever. NG not required.
Flashers on Laser War are tricky due to warming resistors but that's another story.
