Thanks for the info guys. I just went shopping and could not find 14.31863mhz crystal anywhere. So instread I got the 14.31818 in the hopes that it would work. Seems that the 4.31863mhz is very difficult to find as I went to 5 different shops (Akihabara (Electric Town), Tokyo ). I just returned to discover Linards has just confirmed my suspicions.Hope it works.Thanks again
14.31818MHz is the correct frequency, and it is a very common crystal. 14.31863MHz is an unusual frequency, and not standard for an Apple II. Some NTSC monitors may not produce color with this crystal, depending on the directions and amounts of tolerance on the Apple crystal and the monitor crystal. Even some 14.31818MHz crystals drift too far for some monitors. -michael Parallel computing for 8-bit Apple II's!
