Is it possible to run EmuTOS as an AmigaOS "task" already? I know it can
run standalone on various Amiga (and Amiga-related) hardware, but the real
fun - for me anyway - would be to run it alongside AmigaOS. Maybe in a
lightweight VM, like Shapeshifter for MacOS, but course EmuTOS could even
provide such infrastructure for itself. I once even looked at the EmuTOS
code to figure this out, but I never went anywhere with it, because I
realized all the EmuTOS drivers are basically banging the Amiga HW, and
ignore the entire Kickstart.. (Which is understandable from EmuTOS PoV,
but if I want to run it on top of AmigaOS, it means all drivers/etc needs
to be rewritten, which was a much bigger project than I was willing to
take on at that point. Also FIXME, if I was wrong on this.)
I think the main challenge would be sharing the lower 4/8K of RAM, mainly
for TRAP vectors, but exactly for things like Shapeshifter, there's
already a way to handle that. But of course I don't know about various
other Atari-related complications, handling of ST vs. TT RAM, etc.
Overall, I don't know. Just brainstorming. Opinions? :)
