The institute was a pretty boring place, full of theoreticians writing papers. But in a building far away from everyone else, some engineers were building a computer, one of the first to have a fully electronic random-access memory. For a kid in the 1950s, it was the most exciting thing around. I mean, they called it the MANIAC! The computer building was off-limits to children, but Julian Bigelow, the chief engineer, stored a lot of surplus electronic equipment in a barn, and I grew up playing there and taking things apart.
