Well...here I go. I recently aquired an IGT S2000 (Run for your money) that didn't do anything when you powered it on. After inspecting the usual, power supply, molex connectors, and obvious things like loose and tarnished or burnt connections, I could claim no success... Then after a close look at the chips in their sockets, I found the stepper base chip (SB000188) had a pin bent up under the chip, not inserted in the socket, so after carefully straightening out that problem and re-seating the chip...(and doing my share of praying)...I powered on the machine.
To my surprise it initialized and cycled through it's routine, until the "please wait" graphic started forming, then it immediately flashed to the infamous "CALL ATTENDANT...COIN-IN JAM" and "M DOOR OPEN"... So, after reading archive posts on the subject, I've tried another I O Board, also a MPU Board, and a clear chip function, at the end of which it did not read "MACHINE TYPE MISMATCH", it simply initialized again and stopped at the "COIN-IN JAM" error once more. I am currently at my wit's end. I know I'm missing something...This is my first bout with a S2000 and I am obviously a newbie here. I need HELP.
Does anyone think the GME1 or GME2 chips may be my problem?
