I recently acquired a Gamemaker  bartop machine.Mainboard is a V7000 number 22 mains. When I started it up it constantly reset. I checked the threads located some solutions aand replacced the battery. Did the saferam clear with the chip and it sarted up and let me configure the setings. When I exited settings I ended up with a box that states:

Bill Acceptor: No  errors
No Printer
Host Comm LLink Up

It also shows a small box underneath showing a picture of what looks like the bartop with a few rectangles of red. Will try to  post a picture.

I have not been able to get the box to disapppear so the machine is playable. My question is which setting did I miss or is there something else I  need to fix?

Also I do not have a manual. I checked the posts but did not  find a link to one. Any help as always appreciated!

The red boxes indicate a door open.
Check all the door switches to be sure all are operable.
Main Door, Cash can, and Drop door.

Thanks Neon!!!! Been reading everthing and when the top was closed could not see the  door open main message under the black cover. What I think I did was select optin switch instead of manual in the set up. I redid the saferam clear with the chip but it did not let me set up all the options such as juridiction, door switches etc.. still reading...

I think I found my problem with the door switch. In looking at my set up I picked pulse optics and they should have been manual/mechanical. My problem now is the machine will not let me change them. I  have done several clears with the clear chip and all the 1-8 dips turned on via switch 1. When I restart it shows me the setting for the currwnt eeprom but does not allow me to change them. When I  turn the keyswitch it tells me to switch the dip switches, remove the clear chip and restart. When I do it does to the configuration menu with the games set up and diagnostics etc. It doesnt let me into the eeprom set up screen. Any suggestions help appreciated. Guess ya gotta be careful when clicking these buttons :25-

Do another clear, Only this time turn off dip's 7 and 8
This will allow you to reselect your options.

Correction.....
I should have said turn 7 & 8 ON not off
Off is normal.

Evening Neon:

Yup I've tried exactly  that 3 times now. It will not let me in after I initally replaced the battery I got the saferam corrupt message and I  did the clear and it let me set those items up. Of course I did it wrong and figured I would just got back and flip the switches on, put in the clear chip and start over. When I do this each time it lets me see those eeprom options but does not allow me to configure them. The message underneath state turn key to reset. I ven took out the battery hoping that would corrupt everything again and no go. The setting stayed. Am confused now... :103-

Well, it sounds like when you first selected the options you may have typed in something other than "1" for jurisdiction. If so, then your options are now locked depending on the jurisdiction number. Changing your Mains to a different set of eproms should let you get back to options as long as they are not a locked jurisdiction as well.

Thanks Tacman.. No way to unlock them now? :8- If I need to buy new mains which ones do you suggest?

Well, use the chart below. It was made a while back by one of our members. The newer Mains have the Multti-Denom and Tokenization features, but Mains vary depending on the games you are playing. I use 24 Mains and have a mix of slots, poker and keno on my GM.

 Dan (tacman)

I have the 22's in there now. There is a mix of  slots and poker on there. Would have worked fine I imagine if I had picked  the right door switch :30- It lets me set up the mullti denomination and all the games speed and mullti denomiation settings. So  I guess I'll go shopping tomarrow for a new set. Thanks  for the information and the help. I  imagine any of the vendors on top stock them?

Yeah, in your neck of the woods I would say Jim at Blueridge Slots or April at Lemans1969. If you're north of the border then a69mopar at GTA Slots.

 Dan (tacman)

Thanks Dan and Neon for all the help and information. I'll be shopping tomarrow.

Just for giggles, before you order replacement mains, Try the following:

First, remove the battery jumper W17. It's right next to the battery. Leave the battery disconnected for 30 seconds and then reconnect it. This will kill the backup memory and might clear your settings, allowing you to start over. It may not work, but it's worth a try. Make sure that you put the jumper back correctly. It goes on the two pins closest to the front of the board (ON).

Second, have you tried doing a full clear with ONLY switches 7 & 8 turned on (as Neon suggested), and not switches 1-8 as you said you did? It may or may not help, but that is the correct way to do a full clear. Also make sure that you're putting the clear chip in P10. I found out that you can do partial clears with the clear chip in other sockets, but not a full clear. Do this AFTER you've disconnected and reconnected the battery. Be sure to select jurisdiction 1 to avoid this problem in the future.

If you do end up buying new mains, you might as well think about what options you might like to have. In addition, you should be able to change games, mains, and graphics all day long, so once you've cleared up this issue, you will be able to swap the different mains at any time.

The 24s are multi-denomination and tokenized, which is cool, because you can set it up to give you a lot of credits for each coin. Tokenized coins are a faster way of getting credits on the machine than using the bill validator. The downside to the 24s is that they won't allow you to setup internal progressives.

I like the 22 mains, but I think that they might be the same as your 23s.

Another option might be the 20Ts. They They also allow tokenization and do allow progressives, but are not multi-denominational. I have had some problems with these, but it might just be me, since no one else has ever reported an issue.

Thanks for all the suggeestions Stat.  I tried all you suggested and it did not clear the mains. I even left the  battery off over night but it still  came up locked. It was worth a try though. Have to contact one of the vendors and get new mains  :30-


Also need a copy of the gamemaker manual or a location to download a copy. Thanks all.

 :172- :204-

Thanks Stat!!!
Now I can really have fun!!!! :79- Let's see what else I can screw up.. :208- :25-

Ordered the #24 mains from one of the vendors above, should be arrving today and should be able to install them later tonight after work.  :3-

ok got  the new mains but that did not allow me to clear the jurisdiction settings so I am still locked up. In researching threads I found one regarding the jurisdiction chip. I located the chip and removed it. I started the machine and it came up to the menu screen for jurisdiction etc. All items were set to none or disabled, however I was not able to set the settings up. I replaced the chip and my  old settings reappeared.My question is is  there anyway  to clear this  chip. I searched the number on the mouser site per Bunker's suggstion and it  is made by fairchild semi-conductor but is listed as obsolete. It does have a window on the chip. Would passing it under a UV light erase the settings or just damage the chip? I think the chip just stores the setings as the menu came up without the chip in although I couldn;t set anything which means the chip  stores the settings.? Would buying a blank chip solve the problem.? Thanks in advance for all advice and assistance with my journey of dicovery. At least I am learning alot.!!! :89-

Did you try the "Deep Blue" clear chips that Jim at Blueridge has?  They have worked for others with the locked jurisdiction issue.  Wasn't this the same issue that was posted in another thread?

Thanks,
Wayne

I found this pdf document on his chip...>>>see below
I suggested that he get one of these cheap eprom UV erasers... >>>see below
to erase everything off of it and reburn it again.
The only problem is...it's a 2 meg chip...where does the data begin at...lol

If I understand Slotsman's 2006 post from the old site and if it's correct, then you won't need to program the e2prom because the appropriate data will be written to it when you setup the machine. I would try erasing it with the UV eraser and see if that clears the lock.

If it does, then we will all have learned how to clear a jurisdiction lock and you will have saved a few bucks. If it doesn't work, then buy the deep blue clear chip.

Just my 2¢.

Stat :31-

If his part is the type in your datasheet it is not eraseable with UV, it is an Electronically Eraseable part. I checked this thread and did not see a part number listed, but he did say that his part had a window.... maybe he can post a good picture of it and we can check some more for him?
 
CaptainHappy :95-

Yes Wayne it  was and I apologize for the double posting. In trying to solve my problem I came across a thread about the eeprom erasing, switching chips and asked questions there. This thread was about the new mains I ordered and I just didn;t want to leave this thread hanging with people wondering what happend if they  didn;t follow the other thread. I'll try to incorporate the posts to keep it to a minimum. Again my apologies, I just get started with so many questions, I forget where I left off.

CH- I'll get a picture of the chip later today when I get home from work, the chip number is B52AD 93C56N made by Fairchild Semiconductor. it stated on the Mouser site that the chip is obsolete and not made anymore. There are substitutes availlable.  Thanks to Bunker for all the information he provided to me yesterday. Did alot of reading!

Stat - I think that will probably be the next step get this erased and see if that solved the jurisdiction issue. After I removed the chip and started it up, the menu came right up with no settings but would not allow me to make any  changes possibly because there was no place to write them to.  When i replaced the chip the settings were there again.  I was hoping for a corrupted message which would have allowed me to start over. I have not been able to generate that message or corrupt the setup, one tuff machine..lol  Again this is just a newby theory.

My chip is labeled B55AD 93C56N. It is a standard serial EEPROM and has no window. It goes in U3 in the upper left corner on the main board.

Fairchild industries is out of business or no longer makes IC chips. According to my research on Mouser, the correct replacement is PDIP (128x16) 93C56B by Microchip Tech.
Here is the link to the chip:

http://www.mouser.com/ProductDetail/Microchip/93C56B-I-P/?qs=hklUZQQMghPJWY243bW%252bjw%3d%3d (http://www.mouser.com/ProductDetail/Microchip/93C56B-I-P/?qs=hklUZQQMghPJWY243bW%252bjw%3d%3d)

and the data sheet:
http://ww1.microchip.com/downloads/en/DeviceDoc/21794b.pdf (http://ww1.microchip.com/downloads/en/DeviceDoc/21794b.pdf)

Okay, so I removed my EEPROM and had a look. There is actually very little data stored in it.

First, my GQ-4X will read, write, and erase the chip with no issues, except that I had to slow down the write speed from +2 to 0. No adapter was required.
       I selected chip 93C56B (16 bit) and it worked fine.

Second, the machine would not boot at all with the chip erased. I got a BSOD with a large blinking cursor in the upper left corner.

Third, the machine WOULD allow me to perform a complete saferam clear when I put the clear chip in and turned on switches 7 & 8,
         however, I didn't go through with it because I have bookkeeping info that I haven't saved and a RF on one of my games that I wanted to keep. :96-  :97-

Fourth, when I wrote the old data back onto the chip, the machine rebooted (without any clears) and worked fine. All of my Saferam data was there.
           It did record the exception error in the error log when I tried to boot with the blank EEPROM.
Fifth, there is so little information in this chip that a person could manually enter the data and write it to their EEPROM if they wanted to...  :79- :129- :129- :129-  :100-

My V7000 machine was set up with jurisdiction one for 24 mains. Now, I'm not saying that this data would work with someone else's setup, but...  :129- :129-



Here is what my chip looks like when working and after putting the erased chip into the machine. Note that the machine wrote 00 to most of the data as soon as I powered up the unit (replacing the blank FF's). This tells me that the Gamemaker uses only a very limited range, from 0x0D4 to the end of the chip. The rest is obviously not used. The data in mine starts at 0x0ED


Conclusion: Clearing and re-burning this thing is as easy as any other data chip. If this is where the jurisdiction data is stored, then it should be a snap to clear a bad jurisdiction. There is a check box available on the burner to lock and unlock, but I didn't try it and don't know if it applies to this chip.

Awesome sleuthing and digging around Stat!  :131-  :89- :71-

Insomnia. :25-  :47- :30-

ah...great minds work at strange hours.... :200-

Wow Stat .. Awesome data... Will take me a while to digest it and put it together.. Am a few years away from when i used to flash bios on computers with a serial programmer. Not even sure my old one would work on these types of chips.  What I gather, and I might be wrong and will defer to those in the know.. Bunker and I have been batting this around off list and I thouight putting the eeprom under a UV light for a duration would clear the chip.  However, and again i might be reading this wrong or my pretzle logic is off again.. Putting the chip under UV light will clear the chip and the machine would not be able to boot up at all? Subjecting the chip to UV light would be the same as clearing it in a programmer?

To be honest, I've never seen one of these with a UV window. I think that's one of the reasons that CaptainHappy :95- wanted to see a picture of your chip.

IF it is a UV erasable chip, then you must use a UV light to erase it: you cannot electrically erase it with the burner.

An erased chip will be filled with the value FF (bits are all ones). When a chip is burned, only the zero bits are written. The reason the they put 00 in places that are not used is for security. Once the bits are burned to zero, they cannot be written again without doing a full clear. It prevents hackers from adding or changing things.

I can't tell you for certain that clearing the chip will solve your problem, because we still don't have 100% confirmation that this is where the jurisdiction data and "lock" are stored. I like to help out, but I'm not willing to deliberately set my machine to a locked jurisdiction just to try this. :60-

I can (and did) tell you that my machine would go into the full Saferam clear process when I put the erased EEPROM chip in U3, put a V7S-1000 clear chip in P10, turned on SW1 SWs 7 & 8, and powered up the machine.

At this point, it couldn't hurt to try erasing your chip. You might consider picking up a GQ-4X from mcumall. Several of us have one and it's works well for our hobby. It's always a good idea to back up the chips that you have in your slots in case something happens to them.

Thanks Stat.. I would not expect anyone to screw up their machine for this. besides that is my job  :97- maybe we all learn something my my mistake  :89-Yup I was already putting one of these on my wish list as a need to have. I am baffled by my machine not being able to clear. With the clear chip and 7 and 8 thrown. I cannot beleive that the locked  jurisdiction controls the entire process and :208- will not allow a complete clear. I even disconnected the battery and unplugged from the wall and it still retained the settings. I would have thought it would have lost it's mind and started over. the only one loosing his mnd is me.  Am sure the machine is laughing

Well, we always get the last laugh, as problems like this force us to learn more and more about our machines. I had no idea that a GM had an EEPROM or that the jurisdiction could be locked if set wrong, and I never would have looked at the data on that chip if you hadn't posted this problem.

Once you get it working, you'll know that much more about your machine. :89- :71-

Stat :31- ,

Good thing that I finally got to sleep, it looks like it saved me alot of typing! Good job describing everything that I was thinking!!!  :244- :244- :244- :97-

CH :95-

Well after 6 weeks of waiting and 2 orders the programmer finally arrived. Seems the first shipment is lost somewhere between here and there. They shipped another Express mail and it got here in 5 days. :244- Will be a llittle bit til i can get home to try it out and see if I can unlocked the gamemaker from the treaded locked jurisdiction problem. Stay tuned!!!!!  :89-

I am happy to report success.!!!!!!!!! :200- :3- :89- My sincere thanks to Stat, Bunker, Tacman and everyone else who answered questions and assisted me with this quest.  :131-

A brief informatiional here. After getting the programmer, I was not able to verify the write to the chip. Stat gave me multiple suggestions but I was still stuck. Stat finally suggested just writing all FF's to the chip, put it back on the board, do the clear and see what happens. Well I am happy :89- to report that it worked flawlessly. All the main screens were empty and I was able to set the jurisdiction and all other functions with no problems. So it appears that the 93c56n chip is the jurisdictional chip, and if the machine gets locked you are able to clear the chip leave it blank and the machine will re-initialize the chip and you can start over.  Again thank you to everyone and my apologies if I missed mentioning anyone that contributed to this thread and my learning curve. Next tiime I will be reading the manual first  :208- :30- :96- :200-

Good job golflover, and thanks for sticking with it.  :3- :3-

This is great information for all Gamemaker owners to know, should they ever accidentally lock their jurisdictions.  :89-


Stat :31-

I know this is an old topic but I just want to thank Stat for posting his eprom data.  His info helped me out a lot.  My Game Maker jurisdiction was locked and I was unable to change eeprom options.  I tried to erase the 93C56B eprom but it did not help.  It said it cleared the saferam but booted to a blank screen as he described.  Then when I rewrote my previous data it just booted as before with the old saferam data.  I ended up manually entering the data in the last address line from what Stat posted with his jurisdiction info and wrote that to the eprom and it worked and I was able to change my eeprom options.  I also have 24 mains.  This was an incredible help to me that you posted the raw data from your eprom.  Thank you so much for posting that and being so thorough with you information.  You saved me a lot of hassle.
