Blake, do you think you could pull your PKG off that Newton and send it to me (sometime this year)? Wrap it up in a SIT file or something before moving it to a modern Mac. Your MBP will get mighty confused about a PKG file... I could then transfer it over move it over and see if it fires up. If it does, problem solved (and if others want it, the PKG could be shared rather than a S/N number).
I want to beat your high score. you only made it to level 2! I feel mighty.
