The display was in a booth replicating the 1984 Winter CES booth. Here is a Creative Computing article from the 1984 event.

If there was a “hit” of the show for me, it had to be my first glimpse of the supermicro code-named Lorraine by Amiga. There was no hint of the machine anywhere in evidence at the Amiga booth. But, with an invitation to step behind the secret panel, my jaw finally got a change to drop. As far as I’m concerned, the Lorraine demo was reason enough to have made the trip to Las Vegas.
