Another stupid question...

[KLOV]

I know I know... I'm always asking you professionals these dumb weird questions. Problem is I'm always trying to learn and figure things out and why something might be a certain way.

So here's my dumb question...

I have this bootleg pac-man board and the adapter is crazy looking. Can someone tell me what the purpose of this adapter is compared to the newer, pretty, sexy looking ones on ebay?

Thanks
