NES Cartridge Port
Note: Pins 1 through 36 are on the top (front on the top loader) and numbered from left to right. Pins 37 through 72 are on the bottom (rear on the top loader) and also numbered from left to right. This table is oriented so the top of the port is facing left. Pins 16 through 19 and pins 52 through 55 are not physically present on the top loader.

An important thing to note about the NES cartridge port is that its pin pitch (the distance between pins) is actually 2.5 mm and is not the industry standard of 2.54 mm. Many clone consoles use the latter and tend to have connection problems because of this.
