Atronics Crazy Fruits Ram Reset

[ofrielspub]

I just picked up a Atronics Crazy Fruits (VI CL 64 P) 2001, at an auction, its came with no info.  I've been trying to find out what I can about it.  It only came with one key and that only controls the Audit, I can open the door but I can not open the lock box to the circuit boards.  Everything seems to work fine, Its locked up on Call Attendant for Handpay out.  So from reading I need the jackpot key, with access to the cabinet I can replace that I believe.  My question is the Ram Reset,  from posts on here Im guessing I need 1. get to the motherboard and 2. replace the U2 Eprom with a clear one?  Cause its set up as a penny slot now i would like to change that to a quarter value.  Is the ram reset the only way to do that? And does anyone know where to pick one up still(clear eprom)?  Any help thanks you.
