... as the OG author of this thread I should say I /did/ drop in a memory upgrade into my Atari 1040STF. :-) I should write a blog post about that too if I haven't already.
yup, the community is really coming together over this. I'm shocked and happily surprised. :-)
There are gary / buster drop-ins now too. Super Buster has been talked about for Zorro-III, but yeah, the AGA and A3000 glue logic stuff hasn't yet been dropped in.
that's why the later OS releases after amiga/commodore imploded extended some of the memory APIs to say "This needs to be globally visible". That way you'd allocate message memory in globally accessible memory and the MMU could do "things".
(Not that I'm a fan of that solution, just saying, they had to hack around it.)
