Thanks one and all for the quick response to my query about getting
Xkernel to work on a sun 3/60. It turns out that we were working from
the wrong version. The correct version is at:
sol.ctr.columbia.edu:pub/Xkernel/Xkernel.1.4/Xkernel.1.4.shar
That is basically what I used. I did get the "4LAZY.sun3.tar.Z" in
the same directory for the fixed version of Xsun. The main problems
that we had were with a config file that was only for a sun 3/50.
Also the init file that we used before had error. My recommendation
is to get Xkernel 1.4, it works fine. All the error we had before are
fixed. The only problem we had was that the instruction for XDM don't
tell you that Xsession shell script needs to be executable.
Since we have 8MB of ram in the beast we made a 8 MB swap.

Here is the config file I used: (We have B/W 3/60)

# Version 1.2

# At several point below, I make comments about how this may not work
# under SunOS 4.0.x I no longer have any 4.0.x machines left to try
# to config this under. There should not be any problems, but I don't
# want to mislead anyone since I could not test it
#
# BTW, this config file is for SunOS 4.1.x and may look suspiciously
# like DL50
