Still amazing, but the paragraph right after that gives more detail. "Draper's personal website furnishes a more detailed version[1] of the coding of EasyWriter. Draper was in prison, in California, at the time, but under a 'work furlough' program. This meant that while he had to spend every night in prison, he spent each day working a regular job outside prison. This job was at Receiving Studios, a small band practice studio, and while there he had access to a computer, where he coded EasyWriter. He did take copies of the code 'home' to prison overnight to work on it."
