I'm not sure they changed the floor that often back then. Repaint portions of it, maybe. It seems like at some point there was a Jazz logo at center court (or at least it said Jazz), but maybe i'm wrong and that didn't happen until the DC.
I can't help you. I dare say I have seen as many, if not more, Jazz games from the Salt Palace era than anyone on this board, but I don't remember either of those floors. I have never been one to care much about the floor, though.
Yes, you've always been more concerned with the carpet.
During the 1990 season, the last at the Salt Palace, the Jazz had a large, multicolored basketball at center court. It was essentially the basketball you see in the older logo with the purple, yellow, green and purple again.
There was text above the ball on each side that read: SALT PALACE.
Hope that helps.
