I'm slightly miffed that the pictured computer is technically an Apple IIc (though I'm sure they meant the Apple II family). Mainly because there actually was an Apple II computer. I see the original article got this detail correct.

A bit pedantic, I realize, but the original Apple II had a max of 48k of RAM, while the IIc had significantly more ram at 128k. Software is (AFAIK) otherwise compatible between them.

You could bulk them up to 64k if you were rich. They didn't give those 4116s away, though. Good thing RAM is cheap now!
