Diagonal slash in gate diagrams

Quick question, in some of the gate diagrams the input or output connections sometimes have a diagonal slash through them (i.e. in the ALU diagram on page 36, the input and output have a diagonal slash, while the single bit instructions don't).

I assumed that this was to indicate that they're mult-bit busses, but then the CPU diagram on page 88 (I'm using the printed book) has a diagonal slash through *everything*, including the 'reset' input.  But then....  On page 93 the reset is draw without the slash?

So yeah, what's it for?  :-)


Cheers,

Matt.
