After over a year of mucking around, I have finally got my Jurassic Park working perfectly. I had issues with the Left and Right Motor. I recieved a DOA and had to wait 3 months for a new one - anyway - I played it for an hour straight tonight, and the game is certainly BETTER than most DE's and puts some overpriced Bally/Williams to shame.

Take away the manufacturer's label and play the game on its merits. Every collection should have a Data East.
