Fwd: Monrobot XI details

Here is the latest information on the Monrobot XI computers that have become available in Virginia. I'm afraid that while I am quite interested in these, I will probably be unable to acquire one. It seems they are interested in selling them rather than giving them away to good homes. Any reasonable sale price in addition to the considerable cost of shipping a 500 pound machine will probably put them out of my price range. I'm hoping that some public computer collection will acquire at least one of these and make it available for viewing. I would be happy to help in the rescue if anyone here decides to buy one. I would even consider contributing to the purchase and transportation of a machine if it ends up in a publicly accessible museum or collection.
