I've made a bunch of circuit boards in the past but this is the first one I've made for pinball machines. I don't plan to make boards that anyone else is already doing but I needed something like this and haven't seen another like it before. Here is the new PROTO-35 board. It is a prototype board that is the same form factor as the early Bally and Stern MPU boards. I am going to use them for custom test fixtures and test boards. They are also useful for your own homebrew replacement MPU. While not for everyone, some of you may appreciate it and I will have these available for anyone that can use one. Blank board will run $35 plus shipping.

The top edge of the board can take a 32, 33, or 34 pin connector so you can put this in place of any Bally -17, -35 or Stern MPU-100 or MPU-200 board. The other four connectors are in their normal locations so the harnesses will plug right in. At the connectors the 4 pads next to each pin are tied together making them easy to wire up. The remaining holes are all isolated which worked out well for the way I normally prototype circuits. It has tons of space to build whatever you'd like.

I don't have a lot on hand but if there is a demand for them I can always make more. Have some other similar boards in the works that I hope will be useful.

That's cool!

I was just thinking last night how neat it would be if someone could re-route a MPU board, and have the needed circuity for the Arduino and suck for DickHamill 's code/controller. Add a USB port for programming the Arduino, a new header for enable/disable switch, and you're good..

I thought that as well ... only a matter of time!
