2 660 CPUs for one game

[Tilt]

It's been a while since I've installed a blank set.  Best I recall is I wiped the cabinet memory and NVRAM with Ekey 7 and Diag.  Then when the machine booted I up went through the initial setup process and started enabling the games that were installed on the HDD.

The only difference between a new installation is I wasn't starting with a wiped HDD too, so I didn't have to install the OS or the games.

yeah, thats the thing being it is some big time between doing this stuff I forget how it was done. I have finally started to write things down. I cant depend on memory...Will give it a shot and see what happens. I will write it down...Thanks for your help on this. I do appriciate it

Oh boy, i been messing around on and off most of the day with my G23. I keep getting "Recoverable error' Cabinet memory error. I could not get to the Diagnostic key to work right. The volitile memory was grayed out. Finally, i inserted both 7key & Diagnostic key and volatile memory was not grayed. I thought great i got it now. No such luck. Keep getting a error when trying to clear upper cabinet memory. so, i looked closely at the eeproms that were in machine originally. The main number is the same but other numbers are different. i have no idea if this matters or not. Tired of messing with it. i think i will put the original EEOROMS back in and try to clear. May be a few days before i get back to it. what a pain!! Wish I was more in tune with these machines.

Can you post pics of the EEPROMs you bought as an additional set for your machine?

Yeah, i will take picts and post them. it seems this may be the issue. May be a day or two before i can get back to it. thanks for following this

Here are a few Picts of EEPROMS

Those look identical to the ones I've been using. Try using another pair from the batch.  Sometimes these knockoff chips from China aren't the best quality.

thanks for looking. i will try that.

ok, finally was able to get a little time to get back to the beast. Tilt: You were spot on. When i replaced the two EEPROMS with new ones everything went very smooth. Thanks for your help on this.

ok, so now, if i were to pull the Family 14 MPU out along with the two EEPROMS, I can then install the Family 20
MPU with the two EEPROMS that were pulled with Family 20 MPU, fire up machine and all is good right? Ready to play!! Just like or similar to the 044 that folks were doing (me included).

Alright, the only other thing is Tilt, you talk about a socket to put the EEPROMS in. Those little EEPROMS are a bear to get in place properly. I can certainly see where a socket would help. Do you have a picture and / or serial# so i can get the proper one? I tried looking on Amazon but there is a lot of items there. I assume from what you are saying there is no soldering involved right? More so a plug and plug easy in / out of EEPROMS.

Tilt, i really do appreciate your help with this. This obviouslys makes changing out systems way easier. Thanks again. Awesome help my friend

Glad to hear that took care of the problem for you 

That's correct.  Keep the two EEPROMs "married" to the MPU together and that's all it requires to seemlessly swap MPUs.  Make sure you put them back in the same socket they came out of.  Label them however you want Top/Bottom, 1/2, Upper/Lower, or use the U(X) designation on the backplane.  Whatever works for you so you keep install them in the proper socket.

As far as the socket goes, here's a link to one from Digikey, but you can get them from many parts houses. No soldering.  Just put the EEPROM in the socket, and then put the socket in the backplane.

Hope that helps.

yes, it does help. Thanks again for all your help. i got some ordered. this most certainly will help as i really like both the family 14 & family 20 games

Ok, so I bagged the Family 20 project, and I’m going to stick with Family 14 for my G23.  I now have 2 660 CPUs with the same 1TB SSD, both have dedicated video cards, and both have 4GB of RAM.  I have a set of 2 backplane EEPROMs for each CPU.  It works flawlessly.  Power the game off, remove the 2 EEPROMs from the backplane for CPU A, and remove CPU A.  Install the 2 EEPROMs on the backplane for CPU B, and install CPU B.

Up and running!  Takes 10 minutes.  It’s nice to have 2 completely different configurations with different games that can be swapped that fast.

Thanks,
Jason

May I ask what was wrong with running 20 on the G23? Curious because I'm about to get a second cabinet to run FAM20. I really want to jump to the a Crystal cabinet though.

The Fam20 games aren’t designed for the CPU and video card in a 660.  Lobstermania 3 runs ok, but for an OCD guy like me, when I see choppy graphics and stuttering sound, it’s game over for me.  I don’t want to have to talk myself into liking games that run like crap.  Bottom line…those games are meant for the horsepower that a Crystal offers.  But for some, it may not be a big deal.

You are correct Jason. A few of the games do react as you describe. The little I have noticed on my system (same as yours it looks like) It does not bother me. All in the eye of the beholder I suppose

Tilt, i received the sockets. I have the Family 20 cpu and eeproms set aside (running family 14 at time being) I put the family 20 eeproms in the sockets. My question is: How are you doing the sockets i.e. are the sockets changed out along with the eeproms each time or are the sockets always left in place or what? Thanks Tilt

[Tilt]

No.  What I do is like you did with the family 20 eeproms.  Put them in sockets and when you're ready to install them plug the whole thing into the backplane socket.  So you have an eeprom in a socket plugged into backplane socket.  That makes removal and installation much easier as you can do it by hand, no need to pry it out, and if you bend or break a pin you can just put the eeprom in a new socket.
