Cool! I have a 128k Mac in working but not restored condition, reach out to me if interested.
I also have a 512ke, which I'll not be able to part with, as it was my first computer. Still runs the copy of HardBall! I hacked to use the roster from my baseball team!
I really doubt anyone is using a 128k for anything but occasionally tickling their nostalgia buds. The 128k was drastically ram starved even at release, 512k really was the minimum required very quickly.
That may well be an original Macintosh in the picture, but it's certainly not the original keyboard! The number pad did not show up until the Macintosh Plus, which came out two years later.
