370s are like nothing currently supported by NetBSD.

The 3x0 is  some exotic IBM hardware.
To port:
1) You'ld have to be an expert on all of the hardware out there (there's   
a lot!)
2) You'ld have to have unrestricted access to one.  I'm not aware of any   
Colleges or Businesses that would let you reboot there 370/390 to test   
your port of UNIX much less let you experiment with their hardware.
2a) Do you have any idea how much power a 'traditional' 370/390 pulls on   
start up?
3) If you pick up one at auction, you've got to have a place to put it   
(it isn't small) much less a service capable of supplying it with enough   
power.

It seems to me, it would probably be easier porting NetBSD to a Cray!

Now IBM's VM is capable of running a virural UNIX machine concurently   
with MVS, sort of like a MACH Kernel.  YOu could port at that level, but   
you'ld have to have some serious sysadmin level access.  A freind said   
the Southwestern Bell Telephone was running a virtural UNIX machine,   
along with MVS and some other VM, on there IBM mainframes when he left.   
 Some last ditch effort to get out of the COBOL world.

I remember being one of hundreds of drones using one of these in college   
and they realy do suck (in usablily) compared to the modern computers.   
 So why do it?
