Bally 81 Error - Clear/Set chips needed?

[modessitt]

Okay, I've done my share of battery replacements and RAM Clears on IGT slots, but not on a Bally slot.  I looked at one yesterday with the "81" error, and determined that the battery is completely dead.

The slot is a Blazing 7's.  The label on it says SMI 6996 (which according to that long list posted elsewhere should be a French Quarters).  However, the game chips say E594711X-05 (which the list says should be an SMI 6886).  I don't know if this matters or not, as it seems to be a Bally 6000?

I found elsewhere here that there are two clear chips for a 6000? However, that post stated that they get put into locations U28 and U43.  My game chip locations are U18 and U20.

Also, as this slot has a DBV, will I need some type of set chip like the IGT's use?

If anyone can tell me which versions of the Clear (and maybe Set) chip I need, I can contact my supplier for them (hopefully).  I'm already ordering the chips for an IGT, and can add these to that order.

Thanks...

By the way, I notice there is a jumper on the board labeled SRAM CLR.  Would this be how to clear it if needed?  If so, who has the instructions?

Well, while I continue to talk to myself...   

It seems to be a universal understanding that EVERYONE know how to identify what mains they have, as I see nothing in searching that actually tells how to do so.  If you don't have a specific label that has a specific number on it, I don't know how you ID them.

I want to verify that I can use the JW10 jumper to do my SafeRAM Clear, or find out whether I need the Clear Chips.

Here is a pic of my Mains, just in case someone can crack the code for me:



If you need me to type in those chip numbers (if you can't read them), let me know...

I believe you have a S5500, I have attached a doc. that will guide you on performing a saferam clear w/o clear chips.  This procedure works on most s5500 with 94 or older mains.

Thanks.

I printed out the directions.  I assume that the "jumper next to battery" refers to JW8 as the only other jumper by the battery (JW1) doesn't have a jumper on it.

Otherwise, the jumper on the right front is JW10, not J6, but I undertand what you mean...

[rjpohl]

The jumper for the battery is NOT right by the battery, seems like it would but it's not.

Then which jumper is it?  By JW# if possible...

If the "9400" written on your Mains stands for 940000 series, they are newer than the "920000" series and will probably require clear chips. Of course, it can't hurt to try it first without them. The clear jumper is JW10 and is located in the lower right (front) corner of the board. The battery jumper is JW12.

If you have a 5500, you should install a battery holder and mount it on the outside front of the tray so that in the future you can change the battery with the machine powered and the board in place because they eat batteries for breakfast. If you have a 6000, you can just solder the new battery in place of the old one. In either case, I would suggest clipping the old battery tabs close to the battery so that you leave as much of them as possible attached to the board. You can then use them to make your new connections.
