I have had on and off issues with my Whodunnit slot machine. One of the reels constantly acts up. When I shuffle the stepper motor boards around, the problem moves to a new reel. I decided to just remake these boards in an attempt to bring stability to the slot machine.

I am unaware of any other pin the boards are used in.
- The board is the A-19043-1 stepper motor for the slot reels.
- If it is used in another game, please let me know!

I created this thread to see if there is any interest in purchasing a set of these boards if I were to make a small run of them?

Let me know if anyone is interested.

I am targeting to have a couple pcb’s created this week and will test them out.

Will do.

I will socket the lm339 on the new board, agree.

Just ordered 5 PCB’s to test things. Will be roughly a week to get them. Will give everyone an update as soon as I can.

Side note, desoldering the IC off those old boards isn’t easy, IMO. It can be done, but if you don’t desolder IC’s frequently you will see, as I did, it can be a pain in the @#$.

I still need to see the full build sheet. It’s looking like just to print a PCB and populate it with everything is roughly $25 at cost not taking into account my time to populate the boards and test them.

Since I cannot do a large order I can’t really get any bulk savings.
- Populated, it seems like $60 a board will be the only way it’s worth the effort. Could see 3 for $150 deal even.

One option could be to just sell unpopulated PCB’s and folks could build one and populate with their own components. Not sure what the interest would be in that.

I could see 3 PCB’s blank for $40 plus shipping being a possibility. (Or $15 a piece). Would rather sell 3 at a time.
- i used pcbway.com for these first test boards. Will shop around for other options too. Not sure of the quality yet of pcbway.

Appreciate any feedback. Not going to get rich from this, but would like to use it to fund future design needs.

Keep your fingers crossed the reverse engineered boards work
