The computer has an input voltage selection switch on the
back panel to select between
115V,
for USA and Canadian
use, and
23OV,
for use in other countries.
Mouse and Keyboard
When connecting the mouse and keyboard to the computer,
be careful to plug them into the proper ports. Although the
ports are physically identical, they are not interchangeable,
and damage may occur to the main system board if you plug
the connectors into the wrong ports.
Installing Diskette Drives
Make sure that the drive type has been correctly selected in
the SETUP program.
