I have five computers. I have four 575s (those are Macintoshes),
and I have one Macintosh Quadra 660AV. The Quadra is equivalent
to a Performa. The nice thing about the AV computer is that along
with the 31-inch monitor that I have vaulted to my ceiling, I can
project the computer screen onto the monitor. So, it is easy to
do whole-class instruction from one computer, because everyone can
see it when it is put up on the monitor.
