Now, it's "Line 74, a(1) and preoutLow(8) have different bus widths."
You are trying to hook an 8 wire bus to a single wire pin. Have you got an Or there instead of an Or8Way?
If the error doesn't appear to be on line 74, look one line before and after it. Sometimes error message line numbers are off by 1.
Feel free to email your ALU to me, but it may be tomorrow morning before I get a change to look at it.
