Hello, me again :P I almost forgot to tell you, you wrote wrong here on your specification. You said on the specification "one DM7492 IC (2 input Nor gate)", it was suppose to be DM7402 right? :P DM7492 isn't a NOR gate chip ;-)

Oh, wow! That was a HUGE mistake, if someone didn't get the right chip, they'd screw everything up!

Thanks for finding it, Avin! I'm fixing it now =)
