trying to put the finishing touches on my TZ shop job. of course the clock is broken and the game seems to love to make sure i know. anyhow, buy a new rottendog board. put it all back together to no avail.(still says clock is broken. still shows a credit dot). not sure what the test means with slow and fast and backwards and etc, cant imagine i put it in incorrectly, as it seemed to only go one way (put same time on etc). any help or suggestions? thx, yo
