Title: Bally s5500 Flashing 80 FIXED Post by: AcePeter on November 16, 2008, 03:56:36 AM Hello My s5500 is flashing 80. I know it's a code for checksum does not match. How to I correct that? Do I need a clear ram chip? Thanks :103-

Title: Re: Bally s5500 Flashing 80 Post by: typeo on November 17, 2008, 11:45:45 AM you probably just need a couple new chips you can tell which ones by the lights blinking
How many blinks per second 1 = Main EPROM checksum error (u12 & u15) 2 = S Main EPROM error (u18 & u20) 3 = Personality EPROM error (u18 & u20) 4 = volatile RAM read/write error (u67 & u68) 5 = nonvolatile RAM (Safe Ram) failure (u67 & u68) 6 = Battery low Hope this helps Title: Re: Bally s5500 Flashing 80 Post by: AcePeter on November 17, 2008, 12:10:31 PM Thanks could you tell me how to clear the ram I see the jumper. I just forgot how to do it.....Thanks for all the great info. :99-

1 set the jumper so it covers the 2 pins 2 put board back in machine 3 Wile holding in the Test and pseudo button keep holding them in 4 turn on machine still holding buttons in 5 watch door leds for ch c then C L C then release buttons 6 Turn off machine 7 take jumper off 8 reinstall board 9 turn on machine and it should reset and play Title: Re: Bally s5500 Flashing 80 Post by: AcePeter on November 17, 2008, 03:05:03 PM I guess I don't have the 92000 board :37- it never did anything when I tried to clear it..Thanks I guess I will need a clear ram chip?....Would 92000 be on the broad somewhere if so I could not find it :103-
Thanks ACE Title: Re: Bally s5500 Flashing 80 Post by: typeo on November 17, 2008, 08:11:55 PM With 80 flashing you will not be able to clear the machine and clear chips probably will not help you
did you get the code 80 fixed ? if so which chip was it? Title: Re: Bally s5500 Flashing 80 Post by: AcePeter on November 17, 2008, 09:35:28 PM I have some chips coming in Friday from a wonderful member of this site. The battery is dead and the U18 chip is missing...I'm getting the 92000 chips and a battery..and the rest of the missing chip..u18...I will report back....
