Emulator Software
The emulator software will run on a PC and when
combined with an interactive whiteboard and projector
will beam a large working replica of the calculator onto
the whiteboard.

This giant working calculator is viewable to the whole class
and it is also identical to the calculators being used by the
students. The whiteboard calculator makes it much easier
to demonstrate a calculation and also makes it much easier
for the students to follow the keystrokes and calculation
chain. The emulator is simple to operate and easy to use
and has been designed to integrate into an existing lesson
plan with minimal fuss providing a simple to use,
practical and fun solution.

The emulator is protected by copyright and licensed for use on a single site basis and can be used
by an unlimited number of users on the site. The software can be installed on an unlimited number
of PC’s on the site or downloaded onto a server and made available across the site’s network.
