Yo. This has been done and there is a build of MAME for it. Oh yeah, paying $25 for a knocker is just insane.

Here is the definitive source about it:

As you will see on Johns site, you just hack into a 30v power supply from Radio Shack for the power.

There is no substitute for playing Q*bert with a knocker. And to all of you people who make "knocker" jokes, what great senses of humor and sharp wit you have!

If you read my previous statements I am not goin this route.  I am not going to use that specific build of mame because it relied on the keyboard leds, which I use.

I have to make my own...
I even said that in the thread you linked :)

However, where I need ot modify the code is the same, just need to output to a different device.

Just the RS power supply costs $23.00.

Factor in the relay and other misc. components, not to mention the cost of sales tax and the solenoid itself and you will be well past $25.

So what's your point with the above comment?
