MrBigg - if you want to try and repair, there are several threads on how to remove battery corrosion on circuit boards. They all involve acid (I use toilet bowler cleaner), 90% + isopropol alcohol, water, lots of soldering/desoldering - the corrosion makes solder removal difficult. You will need to remove a lot of components, because the corrosion travels along the circuit board runs amazingly far. On top of all of this, its possible to miss something, and you end up with a flakey board.

There used to be someone who repaired boards like this, but I think they stopped - too much work for such small rewards, but since this board is a game plan, someone may be willing to take on the task. However, with new boards available, I think that's your best route. Also, don't throw away the board. Cut off the battery and offer it up for sale. Someone may want it.

I just repaired one for my Son in law's father and I can tell you with the looks of that MPU, I would be willing to bet you also need to repin all the connectors to the playfield otherwise you will have constant intermittent problems with switches and lights not working.

I would see if Robotworkshop has a completed board or a kit, he has done an outstanding job putting them together.

As far as the Kit goes I would rate it intermediate to expert soldering skills required. You have to be able to make clean small solder pads. I have been in this field for 40 years, taught basic soldering skills to FAA technicians, and put quite a few electronic kits together in my time, it took me about 5 hours to complete. I would classify myself as intermediate soldering skills on board level repair

Yeah, that O.G. board needs to go on the bonfire...

Whatever price one of these new already built Gameplan boards sells for is worth it!
I was so glad back in the day when Alltek starting making boards. I'd buy one of those and sell the old battery nuked ones as-is on ebay for $100 to crazy (talented) people who wanted to fix them. Win/Win.

How much should one expect to spend for all the parts needed to build a board? (Board, components, programmed ROMs)

I suggest messaging Robotworkshop for both the do it yourself kit and the fully assembled kit prices. I'm not sure he wants it posted or not but i will say it is VERY reasonable considering the effort these gentlemen have made.. awesome work for sure!

I agree! Just ordered a kit from Robotworkshop and I am looking forward to giving this a try. It is more than I have done before but the instructions look good and I am excited to get Coney Island up and running!

I have an Echo Lake board in a Sharpshooter 2 with a Nova rom. I’d like to either get the correct Rom or one of these kits.

wow thats a hell of a lot easier then the calipers I used didn't know that existed

Thanks for the info, and I'll be calling to get my board sent back from the people who thought could repair it. I'm pretty good with a soldering iron, just need my magnifying glass. I own a custom guitar company, and hand-build custom electric guitars, so I solder quite often. I appreciate all the advice, and will probably try to go both routes on my board, and a new one. I bought a surf pro Saturday that was in a doctor's office since it was new, and it looks like it was timed warped here, so pristine it was scary. I got it for a song, and now at least have a good working machine to play while I fix the coney.

I haven’t been on Pinside in awhile and just came across this exciting project. I love my Game Plan games and have the following:

Andromeda
Captain Hook
Sharpshooter
sharpshooter II
Super Nova
Old Coney Island
Attila the Hun

I will definitely be ordering some of these. Thank you very much for doing this.

I glanced through all the posts and was wondering if there were any current issues for finding parts and where everyone has had the best luck getting all the components.

So I got my new board, and it's a work of art btw Robot. Checked everything out, and seemed fine, voltages really close, plugged it up, turned it on, all three green LEDs lit up on new card, and started checking out my devices, flippers, etc. About 2 minutes in, 24 volt fuse blew, and I lost 24 volts as well. Need some advice on where to start there on that power supply setup please.

I would start with the bridges to the right of the card. There's several videos and steps on how to check them on Utube and on this website.

Is there a place specific where Gameplan games can get chatted up? Have an issue that sort of have narrowed down, but hit a dead end on what my options are. https://pinside.com/pinball/forum/topic/sharp-shooter-ii-all-insert-lighting-is-out

Perfect, thanks.

Just recieved the Gameplan assembled board. Very happy, works.like a charm. Now the fun part repinning all the connectors.

Well I've had a sharpshooter sitting in my shed for a few years that has the worst acid damaged mpu I've ever seen, now it looks like maybe I can make it live!

Maybe Coinbox Pinball Podcast will have to come back for one show and talk about their garage imprisoned Sharpshooter getting new life as well. Must be some sort of rite of passage.

I got my board today and all I can say is thank you! I've had this for over 20 years not working and it fired right up after adding the new MPU. I just have to do some very minor things and the game will play perfectly!

Ok.. this is frikkin awesome! 20 years of not being playable and back to life! Amazing work indeed!

Finally got a chance to assemble the MPU for my buddy's Sharpshooter and it's working great!!! It was a fun project to build.

It finally put to rest an issue we were having with intermittence in the switch matrix. By the time I installed the new board, the column we were having trouble with had gone out completely for like the 3rd time and he hadn't been playing it for about a week. Now the game plays much better in result, most notably the pop bumpers are now super sensitive and responsive, tons of action...They had been on the intermittent/dead switch column, and are now finally working as designed! The memory appears to be working as well, so it looks like his game will finally be firing on all cylinders.

Thank you sooo much for making this happen @pinballj! I've been watching the forum the past couple years hoping for someone to come along and make the next repro Gameplan MPU a reality and you did it!!!

I also gotta thank Robotworkshop for taking the initiative and amplifying the impact of this great project. Making the parts and boards available as kits was huge. (Not to mention they were quickly shipped, well-organized, with detailed instructions, and a socket for every chip. Price was very reasonable too!)

This community rocks because of guys like you! Thanks!

Update on my coney island... installed 3 new bridge rectifiers, cleaned all the connector pins, reinstalled everything, and boom! She's alive and well. Got a few issues with some lights not coming on, and a few of the star rollover things. But it all plays, all bumpers, scores, etc, are now working. Glass on order, and new rubber all installed. Played it yesterday for the first time, and it looks like I'm making serious progress thanks to you guys, and robotworks. Cleanup, and cosmetics still to go, but it's finally alive.

Just looked over the BOM for this board, and noticed a $9 capacitor, do we need the 2% tolerance on this capacitor or can I use the 56 cent ones with 5% tolerance?

The owner of Sharpshooter (whom I bought an MPU from Robotworkshop ) has abandoned the project.

I have an MPU kit for sale, for what I have into it. PM me for details.

I jumped!

I wanted to thank Jeremy and Robert for their wonderful work.

Robert, your solders are so perfect, and the packaging for shipping was top.

I was finally able to play on my star trip, it's a real happiness, and that's thanks to you, congratulations guys you are on top.

Does anyone have any kits available? If not a bare PCB would be great so I don't have to order 5.

I bought 5 blank boards a few months ago. Built up 1 to be used as a backup for my Star Trip “cocktail” machine. However, my ST isn’t at my house, so I haven’t been able to test it yet. I think this is the 1st I’ve heard of this problem on cocktail machines.

Once you’ve tested this fix, can you share the details with me? I may be able to test it over Labor Day, and I am able to address “trace changes”.

slag - I have 4 blank boards (and can share some parts ordering info) if you’re interested.

Jeff

I have V1.4.

Uffe from Sweden here..
I'm want to buy a mpu1 for one of my StarTrip games, the old damage mpu is driving me nuts... I have repaired two mpu's to my other games but this is to hard and i have spent to meny hours on it...
So I hope I can buy one

After three hours of assembly its almost done. Tomorrow some traces must be cut and some wires soldered to fix the displayproblem for cocktail games and hopefully the last components will arrive shortly.
Thanks to all of you who made this possible, soon it will be possible to play on my StarTrip again.

Hi everyone.
Installed my circuit board, it starts with 6 blinks goes for a few seconds then starts over again and again and again....
The soundcard playes the startup tune and if I am quick I can play for some seconds.....
Have the psu and mpu on the bench now...
Some ideas?

It turned out to be a faulty CTC.
