Well, I investigated further. The programs work on a SUN 3/60 or 3/50,
but crash a SUN 3/1xx or 3/2xx.

The reason for this is that the 'nitlib' has hardwired into it to use
the 'le0' ethernet interface. The 100/200 machines use a 'ie0'
interface and, if you access 'le0' on them, rather than returning an
error NIT crashes the machine with a bus error.

The fix is: in nitlib.c change the line

char *nit_interface = "le0";

to

char *nit_interface = "ie0";

(of course, only do this if you want to run the programs on a 100/200
series machine. I wouldn't be suprised if trying to use 'ie0' crashed
a 3/60...)
