You be the cogs that fit my wheel.

And I'll write the common acronym in there, COGS.

We can all be cogs in the wheel of change.

The memory is very like the memory of a computer today, except it was all made out of metal, stacks and stacks of cogs, 30 cogs high.

So this should be red too COGS. So I'll call it overhead.

So this is just three sets of cogs, and it's going to add.

So let's talk about the memory. The memory is very like the memory of a computer today, except it was all made out of metal, stacks and stacks of cogs, 30 cogs high.

Imagine a thing this high of cogs, hundreds and hundreds of them, and they've got numbers on them.

Every one of these circles is a cog, a stack of cogs, and this thing is as big as a steam locomotive.

So this is just three sets of cogs, and it's going to add. This is the adding mechanism in action, so you imagine this gigantic machine.

Now, the reason they used punch cards was that Jacquard, in France, had created the Jacquard loom, which was weaving these incredible patterns controlled by punch cards, so he was just repurposing the technology of the day, and like everything else he did, he's using the technology of his era, so 1830s, 1840s, 1850s, cogs, steam, mechanical devices.
