Dart Board Hack (Help with wiring)

Before I thought you were saying I should do a full keyboard hack (mapping it's matrix out), and then map the combined keys (A1, D6, J10, etc.) to the hacked keyboard. A direct 10x10 to 10x10 mapping would be a lot easier, and appears to be a simple method. Now to see if I can find a 10x10 matrix keyboard. Seems the spare I have at home is a 8x12, would that work?

I've never done this, but I'm almost positive an 8x12 will not work. This means that while hitting some of the segments, you'd be establishing a connection between two contacts on the same side of the matrix, and this won't trigger a keypress. You'll need a minimum of 10 on each side. Like I said earlier, it may be difficult to find a suitable keyboard to hack. So close, and yet so far

Depending on what games you like to play, some of them require you to hit the inner and outer "single" separately.
I coded up some games in C for a class i had and i used http://www.mostdartgames.com/ and some other sites for the rules. I wanted to play 321Zap! and my board didn't play it. I was thinking of doing this exact thing so good luck.

What about that printer interface that was posted here. I think Hoagie made it and it could do quite a few inputs. Not sure how many, think it was 60.
SirPoonga:
62?!?!?!? Most electronic dartboards use a matrix. Shouldn;t need that much then.
StephenH:
You could use 2 key encoders, such as a KE72 and a KE24
