I pulled the boards, but didn't actually sell any. The gigantic power connecter has been clipped out, because it was so neat all by itself. I still have it, but what a mess. At the University of Iowa, I was told they had one connected to a teletype, and were using two air conditioners to keep it cool. It had something like 10k of 12 bit words on the fixed head harddrive, (the case of which has a warning label about being made of beryllium and therefore not to file or scrape it and breath its dust.) As you know the card cage is cylindrical, and the frame is made of magnesium. I was told that the "stabile platform" -- I guess a gyroscope and a telescope, that once was inside of it cost a quarter million by itself. That part, but not the computer itself was quite secret, so they were removed them before sending them off to the Universities. There is a port in the side of the computer frame for the telescope to be able to look through, totake bearings from stars, I guess. When I bought it for $35, I thought it was a satelite! In a way, I guess it was, sort of, short term, with an orbit intersecting the surface of the earth. In spite of its defunct condition, it still looks kind of neat. I always thought it would make a great coffee table -- with a glass top. Lots of gold plated parts, and every transistor and diode in the whole thing has its own serial number. -- John
