The AMAX packet comes with a program called CHECKCHIPS.
If you run that program it will tell you what kind of agnus you have.
So try to find someone with AMAX.
If you only have chipram, your computer will be slower, since all data for
the 68000 will have to be fetched through Agnus. Especially in hires will it
be notecable. If you have fastram, the 68000 can use its databus, at the same
time, when Agnus uses its databus to built up the screen, to refresh memory,
and to do blitter operations.
With no fastmem, you won't use the fastmem databus' capacities.
