Well here's the scoop on some of those programs. A friend of mine has an
Amiga 2000 with 1 meg Agnus (and 1 meg ram). I have a 512K amiga 1000

Dungeon Master- won't work on my machine but works fine on his. It needs
1 meg of memory. Doesn't mind the 1 meg agnus.

Dpaint III - works fine on both machines. Animation won't work on either.
I suspect that is because 1> I don't have enough memory and 2> It must
be looking for Fast Ram and thinks my friends computer doesn't have enough
memory either (since it is 1 meg of chip ram). I hear there is a fix for
this?

So the problems with the new Agnus will be caused by those programs that
assume that chip RAM is 512K and think that the computer does not contain
enough memory even tho it has 1 MEG of chip available (It is specifically
looking for Fast RAM and finding none)
