Quoted from Anim8ormatt:

I've played the pinball arcade one a few dozen times and I just don't see the appeal that justifies this titles high price. Great sound and a fabulous looking machine though. I actually have a side art decal mounted in my game room.

Quoted from epthegeek:

While I don't know of anywhere that "shows" it - here's what's involved:
1. Get a P-ROC from multimorphic ($330)
2. Setup a computer to run it (or contact me, if you want a pre-built ready to run thing)
3. Install the P-ROC board in place of the CPU board
4. Plug in the computer
5. Do something about audio*
Step five gets complicated. You can either hack the existing audio board to have a line-in so that you can run the audio through the included speakers, or you can just use PC speakers. With a P-ROC setup the sound comes from the computer, not the pin, so it has to be dealt with.
Lots more details and info on the wiki (including how to do the audio mod): http://soldmy.org/pin/ccc
