Top 10 Holy Grails of Classic Microcomputer Collecting

I received a tip last year that a long time computer business located in Mobile, Alabama was a virtual storehouse of vintage machines. I payed them a visit and could not get past the receptionist. I was told that they occasionally donated the things to be used in educational institutions but that they were absolutely not interested in selling anything. About six months later I learned that the business had closed. Subsequently, I was told by a veteran employee of this firm that when they shut their doors they hauled two Xerox Altos (among many others) to the landfill. I told this person that it was unlikely that they would ever have been in possesion of Xerox Altos but he was adamant that they were indeed Xerox Altos. In hindsight, I now wish I had fibbed to that receptionist and told her that I was connected with the University of Alabama.
