Quoted from Crash:
Would you consider making a Data East/Sega/Whitestar GI smoother board? Craig Aker made the EnerGI Maestro a few years ago but doesn't appear to be persuing this anymore. Still plenty of interest:
https://pinside.com/pinball/forum/topic/led-gi-smoother-for-data-east/page/9#post-6483071

I would have to do research on this. I have a basic understanding of PWM. It seems that most of these solutions involve some kind of microcontroller programming (aka firmware). Most of my experience is bigger system programming. I have had some experience with embedded system programming but it has been a while since I dusted off the C/C++ IDE (not since my last employer let me go).

I think user herg has previously done a System 11 GI OCD. That solution would fit the bill as those systems are direct on/off relay controlled systems rather than granular triac controlled systems (like WPC).

Quoted from Robotworkshop:
The documentation shows the jumpers for the Williams System 11 boards but I didn't see a section that covered the Data East jumpers although they look pretty straightforward from the silkscreen on the PCB. For the 2ms and 1ms and for the frequency select does the * by the b mean that is the default setting?

When I first wrote up the documentation I tried to make it as complete as possible. Since then documentation has taken a back seat. Actually it could be considered the "backest" seat. I do the bare amount required and sometimes forget to update other areas. It all comes back to the same issue. If I had more time ...

The silkscreen on all boards is consistent in the sense that any jumper setting that has a known default is marked with an asterisk (*). If there is no reasonable default it is not marked. Such an example of lack of marking is 6116/6264 (on Williams System 9 or 11 boards). If there is a known default that is never changed (such as 1ms/2ms) it can be installed as a fixed jumper (wire between the two points). The jumper was faithfully reproduced but practically the configuration is never changed.

Quoted from Robotworkshop:
The other part that isn't clear is the way the lamp matrix is populated. It looks like it can be done the traditional way with TIP42 or with FET devices for the columns. Do you have a suggested build for R201-R208, R31-R38, when the TIP42 is used and also when the FETs are used? If the FETs are installed would all of those resistors just be the 0 ohm jumpers?

Yes. The silkscreen is a little lacking there. The Williams System 11 silkscreen is a lot better. I removed it on the Data East board because Data East packed the components a little tighter than the Williams board and there is not a lot of room left for silkscreen. It is possible to put the silkscreen at the top left of the board but that would be far away from the installation area.

If you look carefully at the specified values in the components for the lamp columns you will see components with two values separated by a slash. The left value is for the BJT (TIP42) original implementation. The right value is for the MOSFET implementation.

BJT (TIP42) implementation:

RA8=222 (2.2k Ohm 8B resistor network)
R201-R208=000 (0 Ohm resistor)
R31-R38=270@5W (27 Ohm 5W resistor)
Q64-Q71=TIP42 (PNP transistor)

MOSFET implementation:

RA8=102 (1k Ohm 8B resistor network)
R201-R208=102 (1k Ohm resistor)
R31-R38=000 (0 Ohm resistor)
Q64-Q71=MOSFET (P-channel MOSFET=IRF9530/IRF9Z34N/FQP17P06)

Quoted from Robotworkshop:
Also, any suggested part numbers for the relay and for the 4.7uH 3A inductors?

You can purchase relays (and sockets) from Ed @G-P-E. You want the LB4H-6 products.
The inductor can be a solid wire (recommend 18AWG not 22AWG). I use Abracon AIAP-02-4R7K. That product is now discontinued by the manufacturer. You can also use something more like the original Williams look if you want. Search for "5551-09822-00" on Pinball Spare Parts. The original Data East board used a toroidal inductor. I chose to use the Williams style inductor to avoid having to stock different parts.

It's been a week+ of building boards. I got the most recent batch complete and sent along with some bare boards. I took some time out yesterday to build some prototype boards that had been sitting around waiting.

Dot matrix display row logic using surface mount components. Soldering done by hand. Super annoying for those tiny resistor arrays. One side of the row logic uses discrete resistors as a test.

boards_175.jpg

Dot matrix display column logic using surface mount components. I had intended on using the TSSOP form factor for the TLC5926 but I decided against it. The spacing is 0.635mm and that's just insane for hand soldering. I also don't have any TLC5926 is TSSOP. I only have them in SOIC so I just used the adapter.

boards_176.jpg

Got everything connected up and it appears to be working. There are some limitations with this prototyping system as the power requirements and signal are transmitted through those tiny breadboard style cables.

boards_177.jpg

I do have a board that is design complete with surface mount for the dot matrix display. It is waiting for fabrication but I don't want to make any until I know that there's a chance it will work. This prototyping provides the confidence. That board is now in the next fabrication order. That may be a while out though as I still have more boards to build and nothing urgent for board fabrication.

Back to building System 11 and System 9 CPU boards.

If you get a break and can confirm the parts for the Data East Lamp section and the defaults for the jumpers I can wrap up the Data East PCB.

Do you have any plans/ would you consider making a system 3/4/6/7 WMS all in one board similar to the RD MPU327?
Even a bare board for end user self population like your other bare boards would be awesome.

Or maybe separate MPU and Driver boards similar to the originals with a better interconnect system?

Thanks for taking the time to read this.

SYSTEM 9 update: Board rocks! Took me a minute to get new cpu chips but DA's Sys9 board is the bomb. Sounds great, excellent labeling. Just a great replacement that I can have confidence in now. Sorcerer is feisty! Thanks again Victor for just stellar work and great timing

I want to take a few moments to comment on what came with my bare pcb purchase, not for sake of its guarantee, just to speak about where these products originate. This is based on my experience alone.

The boards I ordered came from the original batch. The System 9 mpu reconceived by Victor (DA) is thoughtful in so many ways that just make sense. Something that has irked me, from a design standpoint, knowing what these games were designed for - recreational use in a commercial setting that requires ongoing maintenance - is the lack of on-board info, or tools, to assist in troubleshooting a faulty system. DA's MPU adds thoughtful special solenoid testing (optional to install but why the heck wouldn't you? It's a few switches and passives), additional LEDs for general system info/feedback, and perhaps most useful, clearly labeled everything. What does this connector do? Oh, it's lamp columns, switch drivers, it's obvious that manufacturers could have (and sometimes did) added these simple features. Mind you, this is an aftermarket product, and the spread of interest in pinball maintenance wasn't something I imagine they fathomed in those days.

I assembled the board probably 3-2 parts I had - parts I ordered. I purchased the added speech daughterboard to tidy things up (I have a spare speech board now with a couple hard to find chips now) and burned the roms for everything to work. NVRAM installed - check. When I had a couple issues early on, Victor helped with just basic info and guidance. Ultimately the only problem I had was a faulty 6808. Finally got my 6802 replacement and this thing sounds so good, clean, loud, crisp. It's pretty neat knowing I've got a brand new MPU in my game that I built. Thanks to Victor (DA) for an amazing replacement option.

I almost have the display kit for Pinbot completed. Currently waiting for a few components from Mouser and I’ll be done.

I’m sharing quite a few pics since I don’t recall seeing anyone else post a build for them in the thread yet.

I have some other stuff I’m building too, and will echo what others have said - Victor’s kits are pretty straight forward and everything labeled on the pcb saves a ton of time.

Got the Pinbot display build completed tonight! I’m very happy with the results. I did find a couple issues, but was able to work around them.

I’ll probably be making a set of black foam baffles to go around the displays to block out the back box light soon as well.

The displays looks 100% blue and red in person, my iPhone just washed them out a bit.

The biggest snag I ran into was the top right mounting post in the back box was covered by the player 1&2 daughter board. I ended up drilling a hole through the daughter board and rounded it a bit with my dremel. The other issue is that the player 2 ribbon cable (if using the stock cables like I did) was really tight. It reaches and seats fully, but it should probably be replaced with a longer one.

I do not have much experience with System 3-7. From what I have seen and read it is very similar (and somewhat simpler) than System 9 or System 11. I also do not have any System 7 machines to do any testing with. If I were to attempt this the first thing I would need to do is build a bench testing rig. I don't even have one of those. I would start with known good boards (which I don't have) and get an LED display working (which I have not done). You see where this is going ...

I would consider this but I have a few other boards that I need / want to do before I even start with System 3-7. There is the remaining WPC-95 boards, the non-working WPC-89 and System 11 boards. I can really only get to them if (or when) my build work queue reaches zero. It has not done that for months now.

I know that's not what you want to hear but it's reality. Are there not other manufacturers who are making these boards? I thought there were several of them.

I mounted one in my Laser War and don't recall seeing this issue. I'll have to go back and take a look see. It's likely that Williams and Data East used different board mounting spacers.

Build. Build. Build.

I took this photo earlier this afternoon before I completed populating them.

boards_178.jpg

I just completed verifying all of them on my bench so I now need to spend some time packing. I hope there will be some happy pinheads in about one to two weeks time!

Unfortunately (or fortunately depending on your point of view) tomorrow I need to help someone in the region so it will be most of the day taken. 1-1/4 hour drive each way plus time spent. The boards will likely go out in a few days.

Even after these go out I still have another System 9 CPU, System 11 CPU and WPC-89 Power Driver to do. Not to mention I haven't even started a tear down of a machine rebuild I agreed to take on ... or the boards in my fabrication queue that are waiting for fabrication and build/verification once they are received.

I thought there were several replacement options. Some were out of stock for a while but should have more in the next couple months. Never had trouble finding original boards though. The driver works across system 3-7 (just put 0 ohm resistors or jumpers for switch Matrix). The MPU boards are out there too. I’ve never heard anyone mention super rare in regards to the early Williams system 3-7 boards before. At least within the US. Outside of the US is probably another story.

Happy pinballer here! I ordered a WPC89 Power Driver Board for my Bally Doctor Who game. It had a PINLED board from 2005, which while it worked well, there was ghosting in the GI lights on the playfield (with regular bulbs). Victor was great with communications! I got the populated board which he had to make (see several posts above) and I received it 2 weeks later. I posted pictures of the board, front and back to show the excellent soldering job. Once installed it worked perfectly. I love the added text to the front of the board explaining functions and numbers of the connectors. Some might notice a blank area in the upper left. That is because I have a Fliptronics II board and did not need those extra components (plus saved money too).

Thank you Victor coming to my rescue and producing quality tested products for the community!!!

Fulfilling build requests. Keeping me busy. I sometimes take time out to build some of my own stuff but it's usually a lower priority or when I need to take a break from endless building.

Unified (surface mount) monochrome dot matrix display. I know people love their ColorDMDs. I don't really care for them. With a large collection of machines they become very expensive very quickly. The two board solution is cost prohibitive to offer as a solution. The unified solution is only barely comparable in pricing to other products. I don't expect there will be much (if any) demand for this display. I built it for me. I used it as a way to learn about surface mount soldering. It works on the bench. I expect it will work in a machine but I need to do that final test.

WPC DCS sound board. This was my very first reproduction board. It has been sitting around for about two years or so. Wharhed needed a board for one of his machines and he tested that very first board I built. It had an awful hum and after some inspection and review I found the problem. He implemented the solution and verified the hum was gone. So I revised the board and had it fabricated. Works great in Indiana Jones so this board is ready! No image of it in the machine as you can't hear it working. Complete boards will not have the ZIFs. I use the ZIFs for testing purposes.

I have some other boards waiting for testing and another product that passed verification. I just need to figure out how to post a video (create a YouTube account) so that the sound effect can be heard. It's the Speaker Pop Eliminator and it works! More to come in the near future.

Wanted to take the time to give DumbAss/Victor a great big thanks for providing these boards and his help. I could not be happier with the CPU or his customer service.

I populated his DE board however, I could not get it to boot. DumbAss was very responsive and helpful in getting the issues resolved. He provided multiple suggestions as the potential fixes. His responses to my questions was very timely. We finally determined that I had a few bad resistors (Note to self do note buy resistors from Amazon). Replace them and now have a new working DE CPU.

If I over look soldering on bad components I found it a fun DIY project. I also gained a better understanding of board and its components.

Again, many thanks to Victor; one of the pinball good guys.

I would like to thank Victor for his donation to the Project Pinball Silent Auction, the response I got from people was incredible. They couldn't say enough good things about the quality, so many asked for his information I had to create a QR code for this Pinside thread! Thanks again!

I'm a little late but I want to send my thanks to Dumbass/Victor for the fully populated System 11A board and the special solenoid fuse board for my Pinbot that I received last month. I installed the Dumbass/Victor built board and Pinbot works perfect with no issues. We've played about 200 games on it and have had no problems with it at all. It is a very well built board. Thanks again.

I can't thank Victor enough for putting up with my dumbass and for what he has done for Pinball!

I built this system 11b for my Black Knight 2000 with his board... and his patience.

Thanks again Victor!

Thank you everyone for the kind words. I try to separate myself from others by the level of support provided. It is often something that is not considered by shoppers when purchasing a product.

A small announcement and minor product update. I have some small products outstanding that will get updates when they work.

I am planning a long overdue break from building boards. I have family in a different continent. Borders that have been closed for over 1.5 years are now open. I did not go last year due to border closure. Lost time cannot be made up. The time has come to take advantage of the opening. I expect to stop building and/or shipping bare boards for the approximately two months that I will be gone which is effectively the whole months of December and January. I have outstanding builds for about one two to three weeks so I am unable to commit to any more builds until after I return. I can still deliver bare boards up until about the last week of November (around US Thanksgiving). Presently, it might be three weeks before my planned departure but I have learned an important lesson from looking at the side rear view mirrors of vehicles: Warning: Objects in calendar are closer than they appear.

I have been sitting on these small boards for months now. I pulled the components but never got around to building them or testing them. Two features combined into a simple concept. A board and cable solution for the System 11 Auxiliary Power board LED flasher/flipper problem and WPC-89 tieback diode insurance. I verified the System 11 boards. I went to verify the WPC boards but the orientation of the header needs to be flipped so I will flip that and then verify it (get some images).

My original tieback diode solution. I built this about two to three years ago.

The cabling I built.

The new tieback diode solution. A simple wire needs to be constructed.

The same solution is applied to the tieback diode for WPC typically recommended for Terminator 2 and Star Trek TNG. The solution can be used for any tieback diode requirements.

Apologies for some radio silence (in posts and PM). I have been busy trying to complete outstanding orders. I had a couple of days taken out to deal with some local issues. Local issues take precedence as I work within time of day available schedule.

First up is the complete boards. These are packed and will go out today. Facetiously I hope I never see another System 11 CPU board again. Alas ... I have one more I will try to squeeze in before departure that will be self transported to convert an international shipment to a domestic one.

Next up is bare boards. I hope to get these knocked out in the next few days.

Hey everyone

Victor squeezed me into his busy sxhedule & hooked me up w/ a new System 11b board for my Police Force. I gently pulled processors (U15/U24) & ROMs (U21/U22/U26/U27) from the original board & got them in the new board. once I stuck it into the machine & turned it on, adjust error, unplayable, & wired sounds. I quickly turned it off w/o trying to go through the menu.

how can I tell if I put the processors or roms in upside down? they fit either way so maybe I have 1 of them flipped around.

There is a half circle on one end of the picture on the board you are supposed to match the round indent on the chip to that same side. I cant see the board picture in the pics you provided so I cant say they are backward or not as I am not familiar with that board set.

thanks! I hadn't even noticed those marks. going thru my before & after pics I can see 5 out of 6 are good. I'll have to look closer at U24 to make sure but based on all the others, I'm going to guess it's good too.

just checked U24 too & thankfully it's not upside down either. thanks again

The windows on the EPROM chips should really be covered. If they are exposed to light for too long it can start erasing bits. Even if one bit flips and reverts to a 1 it can cause issues. Would help to verify the contents of the ROM chips and if corrupt then erase and reprogram.
