1492 was on the C64/C128.
On the Amiga it was called "the Seven Cities of Gold" and was an improved version. Seven Cities of Gold was also available on the C64 and it was by the same author and publisher (EA).
Far as I remember, there was never a 1492 for the Amiga.
It (7COG)was also one of my favourite games of "all time" Amiga. :-)
