Hi My old hardware try have two reason. One is my first BSD is LUNA68K that is 68030 with 8M memory at 1988.=C2=A0 Current my target have more memory. Second is I think more=C2=A0material world make atomic=C2=A0accident at 3.1= 1. I want less=C2=A0material world. Also I try to support 1136J-S r1p5. I get single user on this. But still pr= oblem. I seem many commit is good. But a few commit make problem. Finaly UNIX started on 32 bit architecture. I hope we remain 32 bit support= .

However, we can't support the full ra= nge of old hardware at this time. We don't have enough people actively work= ing on it. We have dozens of people complaining that they can't install on = old hardware that we used to support because things have decayed. I think i= t's really awesome you've gotten the RT1310 working well. I've never been a= ble to get mine going, despite spending several days on it over the last ye= ar or two.=C2=A0 I've been unable to get my *Plug boards working well.
