Epson Equity II - Manual (Page 33)

There are three ways to reset. Because each is more powerful than the
last, try them in the order listed here:
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 MS-DOS reloads. (MS-DOS must either
be on the diskette or be autobootable from the hard disk.) If this does
not correct the problem, try the second method.
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.
Remove any diskettes from the floppy disk drives. Turn off the monitor
and any peripheral devices and then turn off the Equity II+ using the
power switch on the front panel of the main unit. Wait five seconds and
then switch the power back on.
Turning Off the Computer
Before you turn off your computer, save your data, exit the program you
are using, and then remove all diskettes from the disk drives. Turn off your
monitor and peripherals first, then turn off the main unit using the switch on
the front panel.
