A few questions on the 68020:
	3)  Is there a version of OS-9 specifically for the 68020?  Where
		could I get source code or a generic system for the
		68020 or the 68000?
/* ---------- */

Can't help on 1) and 2), but here goes: so far as I know, OS-9/68000 Level 3
(the version that pages, which will want a 68010 or 68020) is not yet
available. (Sigh; neither is Level 2, which gives each process its own
address space with the aid of memory mapping hardware.)

As for source code or a generic system--you can't get source code for
all of it. That's OK, though, because even OEMs don't get it; you don't
need it.  What you can get from Microware is what they call a "PortPak."
This consists of the kernel, utilities, and source to what is supposed
to be sufficient stuff to get you started on what is specific to the
machine you want to port it to (e.g. sample device drivers, the clock
module, and so forth). If you say you want to do cross-development from
a Unix system or an OS-9/6809 system (I think you can do it from VMS
these days, too--better check with Microware), you'll also get the
appropriate C cross-compiler and cross-assembler. Price for said beast
varies, depending on where you want to start from and whether you want
it on tape or on disk; the cheapest is a port from an OS-9 system (I
think it's $1K to $1.5K), and the most expensive is a port from a Unix
system (I believe that's about $2.5K).

The place to get a PortPak from is Microware itself. Addresses:
