If not, I'd kind of like to see if there is anyone else interested and maybe use this space as a place to collect info and ideas.
So far, I've only thought about this and not really done any work, but here is what I've come up with so far.
I'd like to maintain the original plunger and have an auto plunger (like the way Stern's Iron Maiden works). That way skill shots can still be made, and if someone walks away from the machine it won't continuously search for the ball.
We'll need hardware and software to control it.
To make things simple, I think reusing a Terminator 2 plunger for the hardware should be doable. The machines are from the same basic time frame, and have a lot of similar parts.
Need to choose an output to control the solenoid.
Not really sure where to start here, so I'll list the requirements, but need to start working on the "how to" so a rom can be made/patched.
Rom needs a new setting to set the time the ball can sit on the plunger switch before its automatically kicked into play.
Rom needs to be modified so ball seek doesn't occur when the ball is sitting on the plunger switch.
Rom needs to be modified to include the automatic plunger in the ball seek process (in case of failure of the plunger switch)
Anyway, that's what I've got for now. Any thoughts, or guidance (especially in the software end) would be appreciated.
