Epson 20 - Manual (Page 62)

To reset the computer, MS-DOS must be either on a diskette in drive
A or on the hard disk. There are three ways to reset. Because each is
more powerful than the last, try them in the order listed here:
1. If you are using MS-DOS, hold down Ctrl and Alt and press the
Del key on the numeric keypad at the right of the keyboard. The
screen goes blank for a moment and then the computer reloads
MS-DOS. If this does not correct the problem, try the second
method.
2. Press the RESET button on the front panel. This method works
even when the keyboard does not respond to your commands. If
this does not correct the problem, try the third method.
3. Remove any diskette from the diskette drive(s). Turn off the
computer using the power switch on the right side. Wait five
seconds and then turn the power back on. Reload the operating
system.
