Title: CHIPS MISSING TAGS Post by: rjpohl on January 05, 2011, 10:58:00 PM I had removed the U12, U15, U3 and U4 chips from a 5500 to put on another board. Problem is only the u12 and U3 are marked, the other 2 chips are not marked. Is there a way to determine which chip is the U12 and U4? I do have a chip programmer. I looked at the buffer but was able to tell.
thanks Bob Title: Re: CHIPS MISSING TAGS Post by: Jim on January 06, 2011, 09:06:30 PM Do you know what game they came out of? I have alot of Bally chips if you check the status of the chips on your burner it will tell you the hex code. with that and the type game we should be able to match the two.

U3 5844 U12 FA00 ?1 4227 ?2 0600 theses are 27c512 chips thanks Title: Re: CHIPS MISSING TAGS Post by: StatFreak on January 07, 2011, 12:57:51 AM I looked, and I don't have any 5500 mains with those checksums (including U3 and U12). Sorry.

Title: Re: CHIPS MISSING TAGS Post by: rjpohl on January 07, 2011, 04:05:03 PM do the two chips that are marked have any numbers on them other than u-12 and u-13 the marked chips only have the location marked, no other identification Title: Re: CHIPS MISSING TAGS Post by: Jim on January 07, 2011, 04:21:54 PM I have four sets of mains, will check them out this evening.
the easiest way would be to obtain a common set of mains that work with the jumper clear. any set of mains will work in the 5500, that game doesn't require anything special. Jim Title: Re: CHIPS MISSING TAGS Post by: Jim on January 08, 2011, 01:41:08 AM Bob sorry no match
But for future reference: U3=SE920000-H-3=0057E000 U3=SE950000-0-3=00550200 U4=SE920000-H-2=003F3920 U4=SE950000-0-2=003CEEFE U12=ME920000-H-1=003EF900 U12=ME950000-0-1=0033C600 U15=ME920000-H-0=00321307 U15=ME950000-0-0=0026E43A U3=SE920000-C-3=00570600 U3=SE960000-H-3=00570F00 U4=SE920000-C-2=00400DFA U4=SE960000-H-2=003ED1F1 U12=ME920000-C-1=003A7800 U12=ME960000-H-1=003EB200 U15=ME920000-C-0=002C5688 UI5=ME960000-H-0=0032954E Jim Title: Re: CHIPS MISSING TAGS Post by: StatFreak on January 08, 2011, 03:31:56 AM Jim, just curious. Why did you use checksum 32 instead of checksum 16?
Also, those checksums don't match either of the two sets of chips I have. :103- :128- Now I'm confused. Is it possible that Bally put out multiple versions of each? :99- Title: Re: CHIPS MISSING TAGS Post by: Buzz on January 08, 2011, 04:40:04 AM BOB :172-
