It is my understanding that one of the reasons we have i*86BSD variants is that in addition to the ability to become 4 little seperate 8086's ( which we dont use, right? ), the 386 was the first cheap cpu to support a hardware page table, does our kernel make use of this? > For the same reason, Motorolla processers prior to the 68030 or the > 68020 with companion PMMU chip can't run NetBSD. exaclty which mac is this?

I had a class where we built stuff with 68010's is there anything still available that runs on these mega cheap amigas? wanna part with the whole thing?
