I'd drop MMU from the list since you could also use a 68030 with MMU on
a plain ST with TOS 2.06 for example.

Note that there are two kinds of RTCs ... the simple ones from the Mega
computers that did not have NVRAM, and the advanced ones that have been
used in TT and Falcon and had NVRAM. Maybe you should separate them or
introduce an additional "NVRAM" column?

Mega-STE has SCC, too.

I think it does not make much sense to list the video chips. Otherwise
you have to list "STE shifter" and "TT shifter", too, since they were
different from the normal ST shifter.
