Re: Port help wanted/needed?

Thanks for the answer on this one.  I too have a 4MB Sun3/50M that I had 
hoped to load NETBSD onto as a diskless workstation.  The monochrome 
monitor, while difficult to move around, nevertheless has a very crisp 
display for B/W editing.  But I was unsuccessful at getting through all 
the steps diskless boot steps and then quit when I learned that the 
kernel was going to be too large in any case.

So thanks for posting this.  Time to dust it off and try again.
