As far as we can tell, this is one of two known existing EAI-1000 computers. The other is located in Germany in Dr. Ulmann's Analog computer museum. I'm guessing a few more will be found in the basement of a university building someday. If you have any information on other existing EAI 1000 computers, please let us know.
