I remember when the first Mac came out, completely unexpandable, and The Steve declared that it would never have more than 128K of RAM because that was more than enough for anyone.
Which was ridiculous, because my Apple ][ had 16x that much already.
Your Apple ][ had 2 MB of RAM?!?! Where did you put the auxiliary power supply?!? Perhaps you mean Apple IIgs, right?
I think the grandparent article was pointing out that an Apple ][ could not have 2MB of RAM "already" when the first Macintosh was released in early 1984, since RamWorks' Applied Engineering and other expansion makers did not offer the 2MB option until later. By September of 1984, it was a moot point, since the Macintosh 512K hit shelves (with the third-party option for more memory).
