It was essentially the same game as the vector Star Wars game, only you flew a snowspeeder on Hoth, defeating AT-AT's and chicken walkers (yes, I'm old school) and the Falcon through the asteroid field.
To my knowlege, the game only was released in a standup cabinet, unlike the enclosed cockpit of the Star Wars game (which was later on also manufactured as a standup).
You can still find the ESB cabinet in older arcades, or places like bowling alleys and other such places.
I'm sure if you look around this game has been ported to MAME - in fact, I could be wrong, but like the Star Wars game I believe it was released in different versions for the PC or consoles - essentially an arcade port instead of the classic 2600 game. Incidentally, the 2600 game was used at many K-Mart's and Woolworth's around the World to demo the Atari, for it's groundbreaking graphics.
Keep an eye out for the new and improved http://www.temusb.com/ which is under renovation, but offered up loads of information on all Star Wars games, and where to find ports and emu's.
