This bothered me enough, a handful years ago, to change things a bit:

For getty/main.c:

  	char c;
  
  	c = cc;
+ #ifdef notdef /* hack to get rid of parity in getty */
  	c |= partab[c&0177] & 0200;
  	if (OP)
  		c ^= 0200;
+ #endif /* parity hack */
  	if (!UB) {
  		outbuf[obufcnt++] = c;
  		if (obufcnt >= OBUFSIZ)

For pdp/cons.c:

  		ttychars(tp);
  		tp->t_state = TS_ISOPEN|TS_CARR_ON;
! 		tp->t_flags = EVENP|ECHO|XTABS|CRMOD;
  	}
  	if (tp->t_state&TS_XCLUDE && u.u_uid != 0)
  		return (EBUSY);

  	}
  	if (tp->t_state&TS_XCLUDE && u.u_uid != 0)
  		return (EBUSY);

For sys/tty.c:

Hmm.  It's been a while.  I should fire up the old /83 and get all the
latest patches from Steven applied, while it's still winter, and I can
run it and the VAX without overheating my machine room.  :-)
