2 660 CPUs for one game

[Yoeddy1]

Hi guys,

If I have 1 660 CPU full of games, and I have a second 660 CPU that I want to install a bunch of different games on, can I merely swap the 2 CPUs in and out of the same machine?

Thanks,
Jason

No.  But if you swap the two eeproms on the backplane with it you can (at least with a G23v2).  Just like 3902/044 mpu/eeprom swaps.

Good to know, Cliff!  Do you have a picture which EPROMs those are?

Thanks,

Excellent info. I have a G20 though. I will have to look into that. It's a different backplane. I swap the brain box or just the SSD and clear safe storage only. Will get a processor mismatch if I swapped the bb, turn the key once to clear that. Keep cabinet memory intact and all the denom, sas, validation info is still there. Just have to enable the games after that.

I'll take and post a couple of pictures tomorrow.  The only machine I have is a G23v2, so I can't speak for other models.  I do know there are differences between them though.  The eeproms on the G23v2 that you swap out with the MPU is the cabinet memory.  So when you swap from one to another all the statistics, credits, enabled games stay intact.  Makes it nice not to have to re-enable 80+ games for sure.

Yeah, for sure.  I did that with my Game King 044 all the time between Superstar Poker and Game King 6.x.  Seconds to swap that chip on the backplane and MPU.  Is there a location to verify if you have a G23v2?

ID tag on the side of the machine?  Mine shows G23V2 as the model on the tag.  I've also heard if your cabinet controller (blackfin) board has a yellow handle it's a V2, but I don't know if that's acccurate or not.

Takes a bit longer on the G23 because of the additional cables and getting the damn brainbox all the way in.  Mine hit's the rails about halfway in and I have to fight with it to get it the rest of the way in

Ok, here's some pictures of the EEPROMs on a G23V2.  The part number is 25256E and it's installed in sockets U2 and U3 on the backplane.  I marked mine 1 and 2, you can mark them however you like (top/bottom, upper/lower etc), but they both need to remain with the MPU that they were operating with and need to be installed in the correct location too.  The 25256E is obsolete in a DIP8 package, so I got the SOIC-8 package and soldered it to a 8 pin SOIC/DIP adapter socket for the first set.  I got those from Mouser or Digikey.  After I knew that it would work I ordered some in a DIP-8 package from China on Ebay and waited for a couple of weeks for them.  They're still available on Ebay.  Like the 3902/044 backplane EEPROM it's a lot easier to remove and install the EEPROMs into the backplane by putting then in a socket.

I also remoted the telltale battery off of the cabinet controller board, so if it decides to leak it won't destroy the board.  Without schematics it's difficult to come up with a mod that would allow us to remove it all together.  It appears that the system not only monitors the battery voltage, but also the charging current.  I tried using 3 AA batteries with a blocking diode to prevent it from trying to charge the alkaline batteries, but I still got a telltale battery tilt error. 

I'd be interested to hear if the MPU/EEPROM swap can be done with other model AVP machines.  I guess the price of 660 brainboxes will probably be going up now  .

Yeah, I definitely will be doing this.  I’m thinking this would be a good idea to run Texas Hold Em since I think it is meant to be run standalone.  I need to see that game in action.  Never have played it, but I’ve heard it needs to be installed by itself.

Thanks,
Jason

Unfortunately texas holdem is a lame game on avp IMHO.

Reminds me of Roulette on GK 8.3R. You think you want it but then it's underwhelming once you have it. Screw the GK packages that hog your NVRAM with too much single hand five card draw poker and keno that I never play. I do like the MM though. I just use the OS and MM then add the games that I want.

[millionaire2k]

How do you use the MM and not have all the poker games hog everything up?  Also how many games about can I add without the GK hogging everything?

I think he is saying main menu?

I have installed Holdem along side with other games. It played fine. Was rather bland however. Just playing aginst the dealer is kinda lame. That being said. I recently reinstalled it. Plays fine however this time the machine locks up when loading a different game after playing holdem. Only fix is power down and restart then what ever game was trying to load is loaded.

i have been watching this topic closely. The swapping EEPROMs like on the 044 is great. i looked at the backplane of my G23 and the EEPROMs 25256E are installed already. I did not know this. I have family 20 games installed now. I want to remove MPU and install my other MPU that as family 14 games. Both MPUs are 660. I assume from what is being said i can shut down family 20 remove MPU and remove the two 25256E EEPROMS, mark then for future use with family 20 MPU. I assume then i will install MPU family 14 games along with 2 new 25256E EEPROMS on backplane and machine will wright to them. Since there will be nothing on these 2 new EEPROMS, will i have to clear cabinet memory first? I am not real sure the order of things here so any help is appreciated. Thank you.

The new ones for the Fam14 games will be blank, so you'll have to set it up.

Set what up? Not sure what you mean. I am thinking (please correct me if i am off base) Put in  family 14 MPU, put in new / blank EEPROMS at back plane. There are around 50 games installed already on the family 14 MPU. Once I have done that I am not real sure how to proceed. I am thinking when I switched out from family 14 MPU to family 20 MPU all I had to do was clear the upper cabinet memory then it worked just fine. I am finding myself not being sure how to proceed. Maybe just overthinking it...?

The games will still be on the drive, but you will need to enable all of them again and setup progressives again if applicable.  You are essentially wiping cabinet memory by installing blank eeproms.

Thank you. Just to be clear: slide in family 14 MPU, make connections, install the 2 new blank EEPROMS, turn on machine. Will i need E7 key at this point to set up games? or should i boot with E7 or possibly diagnostics? or will machine just simply guide me when turned on...

Sorry if i am beating a dead horse but things dont seem so easy on these G23 sometimes.
