The downside of the Sun 3/50 is the memory hole between the onboard
4 megs and the 8 meg third-party card. Also, the cycle stealing video
doesn't help either. I could probably get a little improvement by 
using a serial console.

You can't actually boot a GENERIC kernel on a Sun 3/50. :-)

You can even see the INSTALL kernel leaking into video memory. The kernel
that I'm using now is:

-rwxr-xr-x   1 root  wheel  819494 Mar 13 09:34 netbsd

I could make it even smaller.

I have maxusers set to 2, and a look at "sysctl -a" shows that resources
are set pretty low.

I am going to plug the disks into a 3/60 with 24megs and a 3/110 with
12megs, to see if there are any performance differences. At one time I
was using a 3/60 running NetBSD 1.2 to run a low impact webserver.

If anyone in Colorado wants a Sun 3/50 with either 8 or 12 megs of memory,
I have 5 0r 6 of them. :-)

I also have a Sun 3/80 that needs a power supply that I want to get up and
running. I have another 3/80 running SunOS 4.1.1.
