I've been working on a port of MINIX to a custom 68010 board built by myself.
I am now up against the lack of any type of memory management on a simple
(non-MMU) system.  I had originally considered core swapping between a fixed
"runnable" area of memory and an area of swap memory but this appears to
have a lot overhead (about 10 ms for a 20K area on a 68010 @ 12.288 MHZ)
Isn't this also a problem for the Atari version of MINIX?  I'd like to
here some real (observed) numbers from the Atari version.  Any other
ideas would be welcome too.

I'm now considering starting over with a 68020/68851 combination or 68030.
(what a wimp, right?)  Either way I will eventually need a cc which generates
680x0 code.  Will the Atari MINIX use the ACK compiler?  Since I have purchased
MINIX for the IBM, will I need to purchase a new copy to get the compiler?
