Somewhat close Ken....

They will solder a new battery on there for you.

Morning rokgpsman,

I've had the machine approximately 4 months. To my knowledge, other than replacing the battery, no repairs have been attempted.

Thanks,

Hello Ken,

The battery was replaced about 4 months ago....

Thanks,

was somewhat confused about the difference so I went and looked at several of my discarded S+ boards. there is actually two versions of the 10Meg. board that I have. the first one shows four reel chips installed and one for future growth. this board has the four big diodes near the plug installed north and south. the second board type has the reel chips shown as you have pictured, U-1 must be the growth socket for a four reel machine, don't ever recall or did I ever see a 5 reel S+ machine, not to say they didn't exist. I know there were some four reel machines, Buzz had two of them. The diodes on this board are installed east and west of the connector. both boards have different number for the reel chips. So, your board is a newer version, and only have three reel chips installed. you would have to trace the outputs to match the pin outs going to the motherboard to determine which chip runs which reel.

Jim,

That's a lot of good information. I'm going to have to look at the board while I read and learn from your post!!!!

I appreciate your time....

I'm looking at a used MPU. Can I install it on my existing metal tray? Also, it does not have the Game Prom and the Reel prom. Can I use mine from my current board?
Some of the components are facing different directions, but other than that, they seem to be the same board.
I have included a picture of mine and the other one. I would appreciate your help!!!!

Thanks,

-Ed

I rotated my board (Image 296), so they are both the same direction for comparison.

Thanks again,,,,

Well that didn't rotate correctly,,,,

Sorry....

rokgpsman · « **Reply #68 on:** April 17, 2017, 10:12:01 AM »

yes, you will want to move your 2 chips (Reel and Game prom chips) from the old board to the new board. Also, if the replacement mpu board has an old battery you may want to move the new battery you just bought for the old mpu. The replacement mpu should fit on your old metal mpu tray. The boards are often sold without the tray and mpu power transformer. The boards are equivalent, one is probably a little older than the other and things were placed slightly different. I'd recommend you keep the old mpu, you may come across someone that will repair it for you down the road. Where are you located?

Hello rokgpsman,,,,

I want to thank you for this information.... I now feel a little more comfortable buying the board.
Also, I'm located in central Oklahoma.

Thanks again,,,,

Not to drive anyone batty.... but only my 16MHz mpu's have the socket at the U1 location,
although there ARE a few different versions of the 10MHz boards.

I suspect IGT had these boards assembled at a few different places back in the 80's.
Some were made in Nevada in the states, some were probably put together in Mexico.
I'll even bet some were put together overseas as well, judging by the different reel driver chips I see on several of my S+ mpu's.

For everyone's information, I was never really able to solve to mystery of the reel drivers
and what exact IC components cause the reel errors - it is extremely difficult to troubleshoot.
Because of this, I now have about 40 bloody boards collecting dust on the shelves....

I hope to solve this mystery soon tho....as stubborn as I am, I've reached out for help.

Now that's scary Stayouttadabunker!!!! I sure hope I'm getting the right board....
I do appreciate the info though....

Thanks,,,,

from what I understand the 16mhz mpu boards will also work in your machine, they were designed to offer some features that the prev ver mpu didn'f have. But many people report that the 16mhz mpu causes annoying noise in the sound, so you may be better off staying with the older style mpu. The easy way to know which board it is, there is no volume control on the 16mhz boards, they control sound level thru the Test button menus.

Okay, thanks rokgpsman,,,,
I'm feeling even better about my purchase now!!!!

Thanks again,,,,

Well I installed the new board and got the 43 code again.... I took reel number 3 out of another machine and installed it in the Red, White and Blue and no error. So, I guess I have a bad reel. Do I have to replace the reel or do you think can it be repaired?
Now I'm wondering if the MPU board was bad at all....
Thanks,
-Ed

It never hurts to have an extra mpu board anyway.

FastEd · « **Reply #76 on:** April 21, 2017, 02:27:02 PM »

True, true erbs!!!!
Thanks,

Did you ever switch reel 3 with reel 2 to see if 43 changed to 42? Did you put your suspect bad reel in your other machine? Did it still give error. If not, it may have been a bad connection all along.

rokgpsman · « **Reply #78 on:** April 21, 2017, 07:57:26 PM »

I thought he interchanged reels #2 and #3 some time back and the error 43 still happened, leading to the thought that the mpu was bad. But this is a long thread so I may be getting it mixed up with another one.

therockinelvis · « **Reply #79 on:** April 22, 2017, 04:17:18 AM »

Yes, very long thread. I did not feel like reading back thru again. I know how difficult the plug on the bottom of reel 3 can be. Possible he never had it seated all the way or cocked in previous attempts.
