There was a nice bonus at the end of Connected episode 86: an interview with Henry Ford Museum curator Kristen Gallerneaux by Stephen Hackett. On the small number of Apple Is in existence, Kristen said:
There are apparently 200 or so sold, and the locations today of about 46 of those 200 are known. What’s really special about ours is that is that’s one of the of the first 50 Apple Is that were ever sold, and out of that batch of the first 50, about nine of that batch are known to work. And ours works; it’s completely unmodified.
