In the original armor, the slide rule came in one of those nerdy belt holsters

 [Derek Flint's spy watch had a slide rule hidden in the inside of the band but we're getting off topic.]

 

["Does this armor make my butt look fat?" would also be off topic.]

I just read "The Tinkerings Of Robert Noyce" by Tom Wolfe (more on that later) and it got me to thinking about the cultural impact of transistors. This was one of the defining technologies of the post-war era, a period when that particular bar was really high.

Because my mind is so cluttered with trivia that I can barely make it to that door, the first example that came to mind was Iron Man's suit. Transistors loomed large in the popular imagination when the character was created sixty years ago, and Stan Lee made heavy use of the technology. The armor, the gadgets, even the life support system were "powered" by transistors.

 

As many have noted, other than the fact they were small, Lee knew absolutely nothing about transistors, which arguably adds to the charm.

 

 

 Obviously there are less silly examples, but even the hardest of hard science fiction written by people who did understand the technology treated it as at least slightly magical.
