Yeah. <shrug> :)

Thanks for your answer - that gives me somewhere to head.

1) I'd like to see if I can do it using discrete parts. Just coz.

2) This is part of a bigger circuit that uses some other Logic types. I started out by building them all with 4011 NANDs thinking I was being efficient by keeping the parts type count down - but then I ended up with these big long strings of NAND chips.

3) To get a 3x In XOR - I'd still have to combine CMOS Gate chips anyway wouldn't I?

Thanks all.
