guys have got me again. Just what the heck is an optical scanner?"
Ray relaxed. If they hadn't explained that to Hap yet, he couldn't be too late. Their greaser-techie
friend was the only member of the gang who didn't come from a scientific family, and they often had to fill
him in on the reasoning behind their plans. The amazing thing was, he was such a whiz with tools that
once they had explained something to him, he could almost always build it.
"A scanner is a device that will let us teach the computer to read," said Rachel.
"I wish someone would teach me to read!"
"Shut up, Paracelsus," said several of the kids simultaneously.
Seeing the puzzled expression that remained on Hap's face, Rachel's twin took up the
explanation. "Basically, the scanner will photograph a page of printed material, then translate it into
symbols the computer can understand."
"Which means we'll be able to feed information into Sherlock several times faster than we do
now," put in Trip Davis.
"Sherlock" was the gang's pet project-a computer program designed to sort clues and solve
crimes. Trip stood up and began pacing across the floor. His lanky frame towered over Ray, who was
barely more than five feet tall. "It will be like going from a tricycle to a ten-speed as far as our
programming goes," he added.
"But Sherlock won't actually understand what it reads," objected Hap. "Will it?"
"Of course not," said Rachel. "At least, not yet. That's what the information programming project
is all about-turning that material into usable data for the computer. But right now we're wasting an
enor-mous amount of time typing the raw stuff into the computer. The best thing would be if we had this
stuff on CD-ROM or something, but, unfortunately, we don't, and with the communication blockade we
can't get it without a lot of explanation. The scanner is our next best bet. It should save us a huge amount
of time."
"Which means," said Wendy, tugging on one of her blond pigtails, "we might even win the race!"
The "race" Wendy was referring to had begun shortly after the head of Project Alpha, Dr. Hwa,
had gathered a handful of the United States' top computer scientists at the deserted Anza-bora Island Air
Force Base. Their mission: to create a "conscious" com-puter-a computer that could not only think, but
be aware that it was thinking; aware, in fact, of its own existence.
Actually, the gang had started "Operation Sher-lock" almost as a way of getting even for the
disrup-tion the Anza-bora project had created in their lives. With the exception of Hap, whose father had
been chief mechanic for the island's recently abandoned Air Force base, the kids had all been uprooted
from their homes almost without notice when their parents decided to join the project.
Even worse, it had been without explanation. Security on the project was so tight no one not
actually involved in the work was supposed to know what it was about. When some clever guesswork
on the gang's part tipped them off to the real reason their parents had come to Anza-bora, the kids
decided to try to take a shot at the same goal.
