The one they reverse-engineered was "local integrated systems architecture," and despite being meaningless it became the official explanation for the name.
Among the engineers it was referred to as "Lisa: invented stupid acronym."
Years later, when I asked about the name, Jobs admitted simply, "Obviously it was named for my daughter."
The Lisa was conceived as a $2,000 machine based on a sixteen-bit microprocessor, rather than the eight-bit one used in the Apple II.
Without the wizardry of Wozniak, who was still working quietly on the Apple II,
the engineers began producing a straightforward computer with a conventional text display, unable to push the powerful microprocessor to do much exciting stuff.
Jobs began to grow impatient with how boring it was turning out to be.
There was, however, one programmer who was infusing the project with some life: Bill Atkinson.
He was a doctoral student in neuroscience who had experimented with his fair share of acid.
When he was asked to come work for Apple, he declined.
But then Apple sent him a nonrefundable plane ticket, and he decided to use it and let Jobs try to persuade him.
