a pixie

hi
i saw this pixie pic project **broken link removed**
but i am kinda confused
is it the rb7 connected to D7 of the middle IC
then link to the pins from d0 to D7 to the bottom IC?
or Rb7 connected to both 74hc374 ICs
Rb7 to D7 and D7 then Rb6 connected to D6 and D6 and so on
Which one is right?
any ideas?
Thanks
 

Re: a pixie

The thicker line is a bus. It is used to avoid clutter in schematics.

D0 is connected to every other D0 on the bus. RB0 is also connected to D0.
And so on.
