how does playchoice pcb work?

I was browsing ebay and saw thishttp://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3274801938&category=13718 and in the picture it has 10 white bars that look like sockets of some sort and I was wondering, do you put the actual NES cartridge on the board or is there an arcade spefic cartridge that the PlayChoice board needs?

They use arcade playchoice carts. which look very similar to a stick of RAM for your computer.

They also look very similar to what is ACTUALLY inside a nes cartridge, although they don't have the same pinout and cannot be easily adapted because Nes carts are missing the information for the second screen and thus the Playchoice hardware won't indentify them.
