Need Bally s6000 safe ram clear chips

[cpdist]

I have a bally 6000 "In the Money" slot machine. Initially I had the error 88FF. I replaced the batteries and ordered saferam clear chips off of ebay.


After doing a full saferam clear I have the error 83F0 which supposedly denotes the wrong saferam clear chips being used. Some research leads me to believe that you need a clear chip with
firmware written after the production of your main chips.


Does anyone have a source for the latest version of the clear chips? I could also take the files and burn them to eproms myself.


Any help appreciated,
Thanks

Try a complete clear.

Try a complete clear.

I tried both the partial clear and the complete clear where you hold down the test and pseudo buttons. Both same result. Reads "CH" for a moment and spits out error 83F0 when it should be saying "CL"
