In a drafty shed in rural northern California is perhaps the rarest Macintosh ever made: an electronically shielded Mac used by a spy or military agency. The machine appears to be unique, and is so secret, no one knows anything about it.
Sitting on a dusty shelf in an old Boulder Creek, California, barn owned by programmer and author Bruce Damer, the Macintosh SE 30 1891 T at first appears to be a standard all-in-one Mac from the mid-1980s.
