Fruit Machine Chat

ive had a look in the back & cant see anything with "MUX" on any of the boards, do you know where in the machine it would be if it was there?

hi, i just been givin a Bell-Fruit classic Cops 'N' Robbers machine for free the person who gave me the machine said the fuse had gone on the lights so they didnt light up, when i got home i plugged the machine in & nothing lights up at all, it makes all the right noices & the reels move etc...
