The Nintendo Enterntainment System is the US version of the Japanese console, The "Family Computer", or "Famicom". Just when videogames became a dead fad in the US, the NES came & completely revolutionised the industry! Originally, the system was sold with "Duck Hunt", "Gyromite", the Zapper light gun, 2 controllers, & a robot called "ROB".

I found my NES at a thrift store in Lake Tahoe. I paid $4 for it & It was in Mint Condition & came with MegaMan 2! The 72-connectors, which was the cause of what you may know as the "blinking light syndrome", where perfect!

UPDATE JAN 2008

Well I managed to kill the connector accidentally w/ a game genie, so I used the opportunity to kill the lockout chip by sawing through pin 4 w/ a razor blade. Also due to my negligence, the case has somewhat yellowed.
