I got a boxed one (NM), and saw that it was sold on Feb. 28, 1984.
Wonder how long they were sold?
Also wonder about the box design. This one has 10 games on the small picture. Later models had more, but how many different pictures are there?
I got my CIB FC last winter, I know how happy it can make the Famicom collector inside you
My box has the same design (8 pulse line carts), I think there were only two different pictures - this, and the one for later models. But since there were only three launch titles and some of the games on that picture were released quite a few months after that, I'm wondering if there was a "launch Famicom" picture with even less titles. But that's just speculation, I never heard about such a version. I think they also used some games twice on the picture, didn't they?
I did some investigation upon the square button FC a while ago. See my post over on Assemblergames:http://www.assemblergames.com/forums/showthread.php?31995-Famicom-Launch-amp-Square-Button-Famicom&p=553958&viewfull=1#post553958
I concluded that the change to round-buttons must have happened anytime between November 1984 and January 1985.
