The Computer History Museum has fine displays of artifacts that predate the electronic computer: Napier's Bones, slide rules, cards from a Jacquard loom, etc. Most of this stuff is safely enclosed in a glass case, which I'm sure they did specifically to annoy amateur photographers like myself; the vast majority of my pictures of this stuff turned out to be really nice pictures of my digital camera's flash bulb.

I did, however, manage to crop out a nice shot of some pieces from a reconstruction of Babbage's Analytical Engine.

Other equipment on display from this era includes a Hollerith machine for census-taking. The maching has two pieces, which I'm calling the "console" and the "bins". Census information is presented to the machine on punched cards; processing a punched card advances the appropriate counters on the console and/or opens a storage bin to receive the cards.
