You've got punch cards, a CPU and memory.

But the S.H.I.E.L.D. Hellicarrier is like a big thing in the comics and I've never seen it portrayed in one of the films before.

Because if you look closely at the beetle's shell, there are lots of little bumps on that shell.

It used punch cards, which were being fed in, and it ran about 10,000 times slower the first ZX81.

This thing over here is one of three punch card readers in here, and this is a program in the Science Museum, just not far from here, created by Charles Babbage, that is sitting there you can go see it waiting for the machine to be built.
