to
do the
keyboard exercises, insert the BASIC cartridge
now. ,Be sure that your computer is turned OFF.
Then insert the BASIC cartridge in the cartridge
slot. IF YOU HAVE AN 800 MODEL (which has
two cartridge slots), the BASIC cartridge goes in
the LEFT cartridge slot.

to the ON position. If you are using a color TV,
the screen will be blue. A red light will glow on
the keyboard. You're ready
