Fran Blanche's workshop is more than a place to unwind. It's home. "I put a bed in my office," she says. Her fashion business is downstairs; upstairs is a music studio and a laboratory with 30 years' worth of tools. A private collector recently asked Blanche to study part of his Apollo-era Launch Vehicle Digital Computer (LVDC), which NASA designed to fly a Saturn V rocket. "All modern boards would come to emulate it," Blanche says. "Trouble is, there's no information about how it was constructed."
