Thanks, CBMatt, however I have already seen that page myself. There was another place where the game could be downloaded as well... (Not posting any links, nor am I mentioning what the site is.) At any rate, I'm hoping I might be able to find the original release of the game on 3.5" floppies. I have the belief that the game may or may not be abandonware. I'm hoping that Epic Games still holds the rights to that game. I did look at an online ordering site of theirs, and there were pinball games available for special ordering, including 'Epic Pinball', but not 'Silverball'. Hmm...
Speaking of games that can be hard to find, I'm also looking for the Goblins series of puzzle games, but I've already located them on Amazon.com, so I won't need help finding them.
