To my knowledge, Amber 8 has only one feature that is missing in later
versions: RAMD. And even this I believe is only available as a
post-translational modification on top of the released Amber 8 code (what I
mean by that is that it's a patch released by a third party that will
modify Amber 8 to implement RAMD).

But the challenges you face just installing Amber 8, coupled with the fact
that you will receive little if any support for a code that pre-dates many
of the graduate students and post-docs currently working on Amber, will
almost certainly render this a wasted effort (the first version I ever used
was 9).

If RAMD is indeed what you're looking for, you're almost certainly better
off trying a different package that has a maintained version (like NAMD).
If RAMD is not necessary, then AmberTools 16 (as Hai mentioned, released
for free) has every feature Amber 8 has and many more, albeit with slightly
worse performance on CPU clusters.
