Minor adjustments to the Atari side of hardware that I spotted when quickly browsing through it:
The picture of the Mega ST is in fact a Mega STE which was a totally different computer which would be cool to include in the list as well.
Atari Falcon was not the first Atari computer to use the 68030. Atari TT030 was back in 1990. The Falcon also naturally belongs to the 32bit section and the TT030 would make a nice addition there as well.
C-Lab also came out with Mk X which was essentially a Mk II housed in a separate black case.
EDIT: The picture of the Amiga 500+ is in fact an Atari Falcon

EDIT2: Might I also suggest that you combine the identical ST/Amiga games rather than having two identical descriptions of the same game?
EDIT3: Come to think of it, the 32-bitness of the Falcon is debatable... One could say it's no more 32-bit than the Atari ST/Amiga 500. On the other hand, there are valid points saying that it is a 32bit machine. I'll leave that to your discretion.
Other than that, looking good. Keep it up.
