Been fooling around with it a little and found you can:
Start a game, end a game.
Launch each different play mode, great for practising on.
Tilt the game.
Flip the flippers, also turn them on or off (so they don't work)
Lauch and serve the ball/s.
Access the feature programming and audits
Turn lamps on and off etc.
Reboot the game
Error reports.
These are simple things you can do in it. Its a real shame that Williams/Bally didn't get the time to fully develop this technology before closing.
I really want to explore the Tournament possibilities which is a little more difficult but not impossible.
I posted a question to the makers of Nucore on the network-ability of Pinball 2000 plans, have a look at there response in the Nucore thread on this!
