  Is there anyone who got Common TeX to work on a Valid (68020 cpu) machine
which runs 4.2bsd? I compiled it successfully, both initex and virtex. 
I can generate lplain.fmt, but when I test it with small.tex, I get the 
following:

Can anyone tell me what I did wrong?
Also, is there a version of undump that works on such a machine?
Please help.
