Huh? You only get loosely coupled systems using Transputers. At least,
as long as you're using the built-in links, you're only going to be able
to implement loosely compled systems. From what I've head from folks
who've been working with them, the external bus interface of the Transputer
makes it complicated to use in a tightly coupled manner. The 680x0 family
isn't really rough to use in a tightly compled manner, but you certainly
need some external buffering. Newer RISC chip like the 88k make tightly
coupled systems a slam-dunk, and the rumor mill says that the 68040 will
work in a similar fashion. To exist in a tightly coupled system efficiently,
though, you absolutely need caches and hardware cache consistency, which
you don't get in the internal 68020/68030 caches.

I think we're in complete agreement on at least this last point.
