I'm in the process of developing a new operating system on my 2000, and I'd
really like to make the most of my Amiga's hardware to do this. What I'd
really like is to be able to run AmigaOS on the 68000, but set the 68020
running also. My approach would be to run my new OS in the 4Mb of 32 bit RAM 
local to the A2620, and try to communicate with the 68k using message
passing and semaphores.

The advantage of this to me is that I would have a fully-fledged OS to
develop my own OS on, and I'd be able to test it without continually
crashing the system and having to reboot. Also, I'd be able to use the
existing features of AmigaOS like windowing and so on as I/O devices
without having to write my own, and without having to waste `020 CPU
time!

Sounds neat, but will it work? What I'd really like is for someone to tell
me that all I need to do to set both processors running concurrently is
to manipulate autoconfig device x or location y. I'm not a registered
developer, although not for lack of trying (Commodore Australia doesn't 
believe that there are any _real_ developers in Australia!). Can anyone
help me with this hack?
