Following this. How does one get on the list for the boards. I am interested in this as I mostly have system 11's in my coection and love them.

Quoted from DumbAss:If you're interested either post (which you just did) or PM. I have kept a list of people interested but I'm not super fast at doing things so please bring some patience. I'm doing this for fun, learning and to help keep machines going. Projects with no boards ... no problem. I'll just make the board!
No problem. I enjoy fighting my boards to get them up and keep them up, so however long it takes. You are doing the community a favor so take as long as you want and you won't hear me complain. I have also had the thought of just reproducing the original, but not the knowledge or skill. Also interested in those aux boards when then come down the pike. Thanks!
Just so I am up to speed, since it seems like I missed the other thread; are the aux boards already done? Also have you worked up any type of cost associated with the bare aux boards? Sorry if this was covered ready or if they are not done yet. I am very interested in where this is going though.
Quoted from DumbAss:Yes. I started this thread due to a response in the other thread because what we're discussing in this thread is generic and not System 11 Auxiliary Power Board specific. These boards are done and I think I have a reasonable way of communicating the BOM. I wanted to get some more merchants but it's just taking more time than I'd like to fill in those fields. That's time not spent doing more on this stuff.
Before making these available I'm going to have two local friends work through building the board so at least someone other than me has built a board. I do intend to provide support for building the board.Not yet.
Yes. Me too! My problem is that I have so many ideas for boards that I want to get done it's actually more interesting to work on the new thing than to try to make sure all the loose ends on the last item(s) are cleared so they are ready for distribution. I'm trying to temper that with a satisfactory level of completion before moving on to the next thing.
If you need a tester or someone to help with loose ends, I am willing.

I also have at least 1 of each system 11 game if I can assist in any way. I have no problem populating a board too.

I haven't checked back in while so figured I would check the sys 11 progress. I would be happy to purchase an unpopulated board set and repopulate it. Whenever you have some ready to purchase I will buy at least one. If you need someone to populate and test anything, let me know as well. Would be more than happy to help out.
Quoted from Xtraball:Do not hesitate to buy one of these boards! This 16 opto board DumbAss made for me is working perfectly in my STTNG.[quoted image][quoted image]
How does one go about purchasing one of these?
Quoted from Xtraball:You simply email DumbAss right here on this thread.
Ok. I dont see his email, but I sent him a PM. Thanks
Quoted from vec-tor:Williams system 11 has custom sips. One side resistors... the other side capacitors.
Data East mother boards had the components split apart.
Oh yeah, those src's. I replaced some without the capacitor end and have not had issues yet.

Soldered in all the sockets that I currently have, still waiting on a couple. I am going to start populating some of the components that I have and another question popped up. I think I understand but just want to be sure:
Just below the special solenoid connector is a set of switches. Are these just a test feature added on? Thanks again.

Only minor corrections, adjustments and improvements from the revision 02. Revision 03 supports an alternate flipper relay. Instead of the original 4PDT relay it also supports a DPDT miniature relay. The miniature relays are easier to acquire and cheaper than the original cube relays.
There is also a new support board. A 74154 to 2x 74138 board. It allows use of two 74138s (3:8 decoder) to perform the same function as a single 74154 (4:16 decoder). The 74154 is getting harder to find in DIP (still available as SOIC). I believe GPE still has some stock. This board provides an alternative to finding a 74154 or using an SOIC form factor.
For my testing purposes I made a few "helper" boards to use ZIF sockets for ICs so I could swap them and just use a simple boot test or a diagnostic test to ensure an IC works correctly.
The board works on the bench. It needs to go for a little stress testing my Rollergames.

Have you thought about making a daughter board that would plug into a 4PDT socket and have a socket for the DPDT? To upgrade an older original board even? Not sure if that is even feasible or desirable, just thinking is all.
I hate to keep asking questions, but does anyone know if this would work in place of the 6v 4PDT relay? I don't see where it specifies the dimensions.
