Very cool, Dave! I didn't know about that one. Any chance you can
pin-point the issue it appeared in?

I have the 1960 article, but I haven't built the 1960 machine (yet).
The nice case alone looks like it would be a coupla hundred bucks to
replicate today, but I suppose you could just make a bare-board version.
