Hi, I have been having ago at the old school Rat Race and for some reason, after spinning 1 credit it keeps making a dreadful alarm sound and displays 'vtp meter' 
I have tried checking and un-checking long term meters but does not make any difference, I still get the same thing. The funny thing is that it will play fine in test mode. But I don't wanna cheat and nudge in infinite amounts of £1.50 rats and slow down win a gain and get £1.50 after £1.50, it is not as much fun......lol So if any one knows how to fix my Ratty? I would be really grateful. By the way the old win a gain cabinet by Tommy C is ace, loads of fun 
Thanks from K.S.
