The On/Off Switch
Your Plus/4 should be turned OFF when you install or remove car
tridges or any peripheral device such as a printer or disk drive. There
is a red power light located below the keyboard on the left, so you
can be sure whether power is off.
2 The Reset Button
There are two ways to use the RESET button:
1. You can use the RESET button to reset your computer as if you'd
just turned it on. Just press the reset button once. Remember: when
you press the reset button, you lose any BASIC program currently
in memory."
2. If you want to reset your Pius/4 and keep your BASIC program,
hold down the RUN/STOP key and then press the RESET button. When
you do this, your Pius/4 goes to the built-in machine language monitor.
Type an X and press the RETURN key to get back to BASIC. Your pro
gram remains intact in the Plus/4 memory. Just type LIST to display the
program on your screen.
'When you press RESET, the Plus/4 automatically issues the NEW
command, which clears the screen. This can be reversed. See the
PluS'4 Programmer's Reference Guide tor information on UNNEWing
your program if you've pressed the reset button by accident.
