Just my $0.02 worth.

I have not looked into AX25, so I cannot comment on that.  However, I
can comment on some kernel issues that may affect the end choice of what
you use this box for.  The latest linux kernels, meaning 2.3.xx/2.4.x with
their "improved" vm subsystem have not performed will at all on Suns with
older MMUs.  Specifically, I tried running a 2.4.0-test5 kernel on a Sparc
1+ and it got so slow that it took 6 hours to unmount the swap space after
2 days of up time.  The 2.2.xx series seem useable.  So if you use this
box for AX25, then use a 2.2.xx kernel.  (2.2.17 worked for me.)  I don't
remember where I saw this, but someone had prepared a Linux/Sun3 boot
image for use as a dedicated XServer.  Do a search on Google and see if
you can find it.  That would be the best way to start since there is no
distro for that that I am aware.

Now, if you want to improve the speed of the box, solid reliability, or
anything like that, then I would side with Jeremy here and say that you
will find NetBSD performs better for general use on these boxes.  I
presently have a Sun 3/80 that I'm using as a caching DNS and NIS server
for my home network.  I stuffed a large capacity SCSI drive into it, and
set up cron jobs for it to mirror important data from other systems over
night.  With the latest pmap kernel patches in place, this box has been
rock solid and doing a very good job with about 3 months of up time now.

By today's standards, these boxes are hardly speed daemons, but they work
reliably for tasks that are amenable to slow and steady...
