This is pretty cool.  I built this over the weekend from the schematic 
on the blog, and wrote a quickie program to test the logic.  I noticed 
some additional diodes have been added to the circuit.  Mine seems to 
work fine without them.  What benefit does this add, and is D3 
backwards?

I recall some joyport games, but its been a really long time.  Anybody 
remember any titles?
