April 1 is the deadline. Many of the computers may be useful for research or historical purposes, perhaps to help put into some context how far Moore's Law has got us over the last 50 to 100 years
To think computers started with vacuum tubes, as transistors. These aren't that old but they do take up a lot of space. Often it is discovered something is needed just after it is thrown out. Perhaps throwing it out was a reminder that something still existed, but it's easy to forget how we got here if there's no hard copy. Human memories can be very subjective. Computer memories are much more logical. The way humanity works, if we bury them now in a few years well regret we didn't wait until we had at least generated a 3D Graphics program that contains all of the information, from hardware layout and format to programs, in the one folder. It will be too late then, we'll have to be content with b/w photos, and perhaps personal descriptions.
Maybe Wikki will tell us what they were like.

Just as Henry Ford had the foresight, insight, and means to establish The Henry Ford Museum & Greenfield Village, one would think that one of our modern visionaries such as Steve Jobs, Bill Gates, or any other of the many well known Silicon Valley technology tycoons would step up and take on the challenge of preservation of these important artifacts.
