Installation/Support Tips
Power
The computer has an input voltage selection switch on the
back panel to select between 115V, for USA and Canadian
use, and 230V, for use in other countries.

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
