The Apple 1 prototype sold for $815,000 USD... hang on to the 1984... you never know.

"A prototype Apple 1, a holy-grail item in electronics memorabilia, has been sold for $815,000 (£618,000).
Apple co-founders Steve Jobs and Steve Wozniak built just 200 of the computers in 1976.
The model auctioned this week contains tell-tale signs that it is a prototype, probably made prior to its manufacturing run.
One computer historian says it is "one of the first, if not the first ever" Apple computer.
This "celebration edition" Apple 1 was expected to make $1m, but auctioneer Charitybuzz told the BBC that the final bid was $815,000.
That means it is not the highest-grossing Apple 1 computer - that distinction belongs to a rare working version that sold for $905,000 at a Bonhams auction in New York in October 2014."

Ok here we go - a small number of things to scratch the surface:

A Lichtenberg "captured lightning" in an acrylic cylinder. My dad made this in the 1970's:

Do you know what that piece of plastic is?

A: It's a linear accelerator test target and judging by its size, a powerful one.

In college, I worked as a machinist in a shop that made various parts for a company that made small medical linear accelerators (I personally drilled four water cooling holes in each of about a thousand cavity blanks). The finished accelerator was about a meter in length. I have a similar target that's only about an inch in diameter and an inch long that was produced by our customer (with a itty-bitty tree to match).

At the SLAC Visitors Center, they had one that was about six inches in diameter and nine inches long, with a tree to match. The SLAC linear accelerator is two miles long! That's why I judge yours came from a powerful one.

I agree Nardi makes very nice steering wheels. My only one is still attached to 1980 Fiat 124 spider.

Did you happen to watch that video I linked earlier? What I find fascinating about the process is how they basically use the LA to pack the plexiglass full of electrons, and then to create the "lightning" they hit it with a hammer to discharge them all. And as for big, the ones they were making in that video are really large compared to mine. I wish there were more information about the accelerator, but they specifically stated they were unable to say anything about the company that did this, and I guess the specifics of the accelerator too. Considering though that the process took about 20 minutes to load it with electrons, perhaps the overall size of the accelerator doesn't matter that much, and it's more a function of time spent being charged.

My interesting item: A pin from the 1941 inauguration of FDR. This one is quite interesting as it was the unprecedented third term of Roosevelt and it has a family story. My great grandfather was a war correspondent for the Washington Post and the story is he knew FDR on a first name basis. Gotta keep this one and frame it one of these days...
