nes motherboard measurements

[pdiddles03]

So I know this sounds like a stupid question, but I'm going to make my first attempt at building a hand held nes system using the original nes. Does anyone know the length and width of the motherboard? i don't have one yet but plan on buying one. I want to start drawing up the plans. and also the length and width of the 72 pin?

thanks in advance.

It is roughly around 8"x5" when I measured it.
The 72pin slot that comes with the Nes (with the tabs) is about 5.5"x1".
