I will: Helios is just a UNIX look-alike, it isn't equivalent to
it (in my view). Why? Well, essentially, it's been designed to run on a
network of transputers and not the 68030!
Helios is a multiprocessor system, though it's *not* a tightly coupled
multiprocessor system (i.e. shared memory, etc) but rather a loosely coupled
multiprocessor system, each transputer is running its own (Helios-)kernel.
Communication is done via transputer links (If I remember correctly, 20Mbit/s).
Thus, Helios for the Atari could perhaps be compared to Mach (-> NeXT,
comp.sys.next) which *is* a *tightly coupled* multiprocessor system.
