About a third of the way into CHRONOS, there's an important scene set in the Computer History Museum, located about half an hour's drive away from San Francisco. More than a few readers had visited the real museum but had never heard of the Visual Storage room. Was this an invention of my imagination, they wondered?
My answer is that the room not only most definitely exists, but it's the highlight of the whole museum! I visited in 2009 and spent far more time in there, perusing through the rows upon rows of historical computers, than I did in the rest of the place!
The doorway to it used to be rather tucked away but I'm told that it is better signposted since the museum's new entrance was opened. As you enter the museum, look to your left and you'll see the corridor that leads to it.
You can get a sense of the wide range of computers on display in the room via the Museum's website.
