D. Bell's game of life don't run on a 4.2bsd Sun.

The game seems to start up fine, but doesn't accept any input.

The bug was in io.c function tty_char() which returns character
as integer.

Problem was that the order of bytes within word
is different in VAX and Sun. 

function tty_char should read(2) the character to char ch; not int ch;
and cast it upon return.
diff io.c.orig io.c follows:
83c83
< 	int	ch;			/* char to return */
---
> 	char	ch;			/* char to return */
103c103
< 	return(ch &= 0x7f);
---
> 	return((int)(ch & 0x7f));


PS.
The life is GREAT!

Try also ;rules 1357 02468
and some small figure.
