I always associate the Amiga with the checkmark, is this a 1980's thing? , I really don't remember seeing the boing ball that much before 1992.... maybe my memory isn't what it was....
The first time I saw an A1000 with the boing ball was one of the first Amiga shows in California in early 1986. It belonged to one of the original Los Gatos developers. Later on, IIRC, there was a company that sold aftermarket boing ball replacement logos for the A1000.
The checkmark was a Commodore marketing logo. The Los Gatos team only wanted the boing ball. The first boing ball that had anything to do with the Amiga was the demo that Dale Luck and RJ Mical (aka "the dancing fools") made on the eve and morning of the first Winter CES the Amiga was shown at.
