San Francisco Trip Part 2 - MOAH
Part 1 is here.
We dropped by a small house museum called the Museum of American Heritage (MOAH) on the way to Stanford University. I wasn't sure what to expect but it turned out pretty good. A pinball exhibition was ongoing when we were there so that was fun to play with. And there were many interesting old gadgets. A volunteer named Jim was guiding us throughout the visit.
Ever wondered why pinball is named so? Well, when they first made it, it was literally a bunch of pins and a ball, no flappers or anything else. Hence the name "pinball". The earlier machines didn't require too much skill.
Jim the volunteer told us is that quite a few pinball machines had nice backglass arts that expressed many progressive social ideas for the time, like female astronauts. Supposedly, those backglasses are more valuable than the pinball machines themselves.
The Intertype machine made typesetting dramatically faster. At the backside of the machine, there is a cylinder of molten lead. As you type on the machine, the moulds for the letters you type fall into the tray in front of you. Then as you "flush" the current line, the molten lead is cast into types that you can use to publish newspapers faster than ever.
This machine helped the invention of daily newspapers. The machine was very expensive so people came up with various ways to keep it busy 24/7. One such way was to typeset a national newspaper earlier in the day, then to typeset a local newspaper later in the day (I think this is kind of similar to how earlier computers were all time-sharing systems; Computers were very expensive and valuable back then).
Unfortunately, I didn't really get to see it running live. They stopped running it live after many parents expressed concerns about their kids (at the museum) being exposed to lead fumes and all.
