Epson Equity II - Manual (Page 13)

In the vertical position shown in Figure 1-2, the main unit stands
upright on its side with the keyboard and monitor beside it. The feet on
the right side serve as the base when the main unit is vertical. If you
choose the vertical position, contact your Epson dealer about a mount-
ing kit to stabilize the computer.
Figure 1-2. Alternate system arrangement
Of course, if you have special computer furniture or want to custom-
ize your setup, you can arrange your system components to suit your
own particular needs.
Before you connect the system components, take a look at the front
and back panels of the main unit.
