Title: Proslot 5500, SafeRam Clear procedure- Jumpers or Eprom chips? Post by: MarkInAz on March 03, 2009, 12:22:50 AM I see there are two different ways to do a SafeRam Clear. I had a error code 81, then after changing the battery I'm getting the 83F error. I tried the WJ10 Ram Clear jumper and held in the two buttons (Test & Coin) but I only got a Partion Ram Clear indication (CH-P). So I assume I need the two Ram Clear chips.
I also read something about the part number on the Mains & how that can make a difference too. Can you expand on that please. Here some part numbers off my Bally slant top if someone can decode them: Model # S63M3B-05 Ser# S940303020 Date 3/94 6461/SAB-5006 CPU Part: AS-3356-201 Rev G U12: ME920000-C-1 U15: ME920000-C-1 Thanks in advacne for the great wealth of info I consistently receive here.

I'm still curious about the other issues I've read about, how the "old" mains wont allow you to do this or someting like that. Also, how do you decode the model number on these Bally's to confirm a 5000, 5500, or 6000 machine etc. I have the Bally ProSlot 5500 manual (thanks to NLG) but have not found much info about these issues there.
