So there are lots of 020/030 accelerators for the SE and Plus (actually not sure about 030s for the Plus but I think so anyway). Some of them have RAM slots that let you go above 4 MB, either as a ramdisk or by using VM, and at least all those with the 030 must have a PMMU in there. So, would it be possible in principle to run NetBSD or Linux on and SE or Plus upgraded like this? What would the obstacles be? Just curious.
