If you've never seen this machine work before I'm wondering if the game software on the cpu board is actually for quarter use, despite the 5 cent decal on the front. That might explain why the CLEAR procedure isn't working, since you ordered a 5 cent denomination CLEAR chip. Is that possible? Can you verify some other denomination things on the machine, like the coin entry slot and the coin comparitor on the inside of the door, are they for nickel or for another coin?

Did everything and no 5 shows up, put data eprom back and does same, upon start up game change 2 then need clr and I made sure chips were installed the correct ways.I cannot see if the cpu board has anything  just saw this in the manual and knew my battery was dead and dead for awhile

After installing the CLEAR chip and turning on the machine how long did you give it to run? Did you get any indications, like any sounds or display messages?

Also, just to make sure, are all five of the red LED's on the righthand side of the I/O board lit, meaning the power supply voltages are ok?

Not likely to be the problem but have you double-checked that the battery you installed is good and that it is installed correctly? Do you have a meter to verify the battery voltage?

Have you ever seen this machine work, or has it been broken ever since you got it? Perhaps the cpu board is bad?

 (Make sure the CLEAR chip is for the same denomination as the game chips on the cpu.)



FYI , the CPU eproms are not a dedicated denomination. The Clear chip denomination determines that.

I have never seen the game work, the slot fits only nickels, all  5 lights in the card rack come on except for the far left light away from the 5 lights. And the battery reads 3.5 volts. I gave the machine up to 5 mins for the clear chip to give me the 5 amount, it just stays blank. Lol if I wasn't prior military and like the game theme so much I'd probably switch games.

All 5 lights  indicate both power supplies are good..   Is there corrosion around the dead battery... A red flag for me is that you aid the previous owner said it worked on and off.....   Is your preference for nickels or quarters ?    Pull out both boards and carefully inspect app gold metal pins to ensure none are bent at all.. put boards back in firmly... Also check both boards for any corrosion around leads or burnt out areas... And believe it or not... give the boards a quick smell for that burnt metal smell...   With the previous owner saying it worked on and off you might just need a new CPU...  Bill

I prefer nickels, and is the cpu easy to obtain and reasonable if I have to go that way. I've kinda checked boards with no smell or burnt spots

Since your cpu board doesn't complete the clear process and you've tried 2 different clear chips that would point to the cpu board being bad. But nothing is absolute when troubleshooting like this, to know for sure you'd need to substitute another cpu board in your machine (or try your cpu in a good working machine). I see them come up for sale now and then on ebay and Rudy's:

http://rudysdeals.com/index.php?route=product/category&path=90

Also some of the NLG members here have boards for these machines that they sometimes sell, you could post a request for a WMS (aka Williams) 40X machine cpu board, I think it is the same part number cpu for the 400, 401 and 40S5 models. Your cpu is part number 5779-13910-02, part number 5779-13910-03 will also work, it is just a slightly newer version of the same board.

You would buy the board and then transfer your socketed game eproms (5 chips for your game) to the new board. Be careful about getting the correct cpu board, WMS made a similar board for use on a different model machine that had a video display instead of spinning reels, it won't work in your machine. There are part numbers printed on the cpu board, that is the best way to identify them.

If the cost of another cpu board is high then perhaps the best option would be to try your cpu board in another machine and see if it works or not. That would prove if your cpu board is good or bad before you spent for a replacement cpu. Did the place or guy you got this machine from have others?

If Dale doesn't have an extra board; I might have one...   A new CPU board would be my logical guess at this point though.  Bill

That's what I'm thinking too, but I'm also wondering if the backplane board that has the security eeprom might be bad instead. Doesn't the clear process format the cpu ram and reinitialize it, plus write to the eeprom on the backplane board? If the eeprom is bad then the clear process may not be able to complete.

Those IO boards can cause some of the oddest problems......

I'm sure Bill or myself can help with any boards, CPU, IO backplane.

Is the security eprom an easy fix and try prior to trying a new board and is there anyone that checks boards to see if mines bad

The security eeprom is either soldered onto your backplane or it is socketed (I've seen a few this way, but the majority are soldered).  It is an 8 pin dip chip (the only one in the backplane) and if you have decent soldering skills, you should be able to replace it.  If it is sockted, it is obviously super easy, just swap it.   The chip itself is under $3 in most places, and it is certainly cheaper than buying a backplane, but as with all obsolete machines, you should be stockpiling parts while they are available for any future replacement if you want to keep the machine for a long period of time.
If you find the site helpful, consider becoming a contributing member.  It pays for costs and keeps this site alive.  I do not respond to requests for private, one-on-one help. Your questions should be posted in the appropriate forum where they may help others as well.

Where are you located? I can check the boards if you pay shipping both ways. You might be closer to Bill or Robert, I 'm sure they can check them too. You would have to send both of them . As for the security chip I am not sure but there is only one on the IO board that is removable, you may need a special burner adapter to copy one, I don't have that capability to copy one of those types. On the CPU board the only removable chips are your game chips, not sure but at least 5 and maybe 6. Some games don't use the XU18 if I remember correctly. Somebody else may be better help then this....

EDIT - more info added

The backplane board is mounted behind the card card. Both boards inside the card cage (I/O and CPU) slide into connectors on the backplane board. Notice the small chip on the backplane, that is the eeprom. You don't have to program it on a prom burner, the machine writes and reads it as needed. The backplane also has several wiring harnesses or cables connected to it from various assemblies in the machine, like the spinning reels, bill validator, meters, and the stuff on the inside of the main door like displays and coin acceptance parts. That's why the backplane is sometimes called an interconnect board, it is a central location where just about everything connects to each other.

The XU18 on your cpu board is not a security chip and it's not very small, it is a full size 32 pin chip. It is one of the sound eproms, but your game doesn't use it, some games have more sound effects than others. The other 3 socketed eproms near XU18 are the sound eproms - XU17, XU30, XU31. These 3 chips, plus the 2 eproms at XU2 and XU3 contain the game software.

If you are not able to get thru the hard clear process or get the machine to work I'd think about taking these guys up on their offer to test your boards. That way you'll know what does or does not work, then you can see about getting any needed replacement parts. Or you could guess at what is wrong and order the part, might get lucky and that's all it takes to do the repair. But that may not fix it and you'd have to order something else, at least you'd have the extra parts as a spare, but that process would probably take longer to get the machine working.

The only chips you have on the CPU are game chips. XU2 is your % Chip, XU3 is a game chip. XU17, XU18, XU30 and XU31 are sound chips. In some games the XU18 is not used. Sorry for the confusion.

It's been a long time since I worked on these, but it sounds like your doing the clear correctly. You just need to be pressing the button to continue past the error. Here is the last few steps your missing. Read them and follow exactly.

I n s t a l l t h e G a m e C h i p

❑ 15. Reinsert the Data EPROM in socket XU3.
❑ 16. Return the CPU Board to the card cage. Engage the board by pushing its white board ejector tabs toward the cage.
❑ 17. Close the Card Cage Door.
❑ 18. Slant top machines only: Reengage the coin chute.
❑ 19. Turn GD power ON. The message "clr" should appear on the Credit Display. This message indicates proper clearing of the RAM. If you've also performed a game change,       "6AnnE         CHAn6E" appears first. [big]Press DIAGNOSTIC to load the new game information. Then "clr" appears, indicating the cleared RAM.[/big]
❑ 20. Lock the card cage.

• R e i n i t i a l i z e t h e S y s t e m

21. [/color]Push the DIAGNOSTIC button. The machine shuts down and reboots. If you cleared the machine properly, the message "clr" appears on the Credit Display. Push the DIAGNOSTIC button to acknowledge this message.
❑ 22.
Close and lock the Main Door.

Also question anyone know what the wiring harness p8 its just up and behind from the door open pin every time I wiggle it it makes noise through the speaker, could that cause my problems on ram reset and what is it?
