In a lot of
cases Commodore shipped prototype machines to
various maufacturers. I believe they used Sun systems to
develop the original AmigaOS. 
They used Stratus 68000 boxes in the very early days.   I remember
that; I don't remember the use of Suns quite as well. 
 
Yes that was it. I was confusing them with the Sun machines that the Los
Gatos team bought after they were bought by Commodore.
