Title: BALLY PRO - RAM CLEAR - ALL 9'S - RESOLVED - NOT! Post by: FOXSSLOTS1 on October 23, 2009, 03:13:55 PM Trying to clear a game that has a 31 code at startup - door open no less - I did the safe ram clear - that works but does not clear the error - using CLEAR CHIPS - I get all 9's winner paid - credit and coin all show 9s.
Went back to ground zero - burnt all new U3/4/12/15 onto ST (SGS) eproms - and ALL IS WELL - I give up on using TI AMD - seem to cause more problems than they are worth Still getting the all 9's - only with clear chips - no matter which manuf - which speed - I keep getting all 9s in the meter window. I use ST 120ns for the regular U12/U15 and I can do a saferam clear - if I use the ST 120 clear chips all 9's - the cksums are correct U12 8e00 and u15 3073. I have 2 original clear chips that are on TI 27512 120. |
