Epson 386SX - Manual (Page 31)

Using the Mouse Connector
The Equity 386SX has an auxiliary port for a mouse that uses a
mini DIN (6-pin) connector. To connect a mouse to the built-
in mouse port and set up the computer to use it, see the manual
that comes with the mouse. To use a mouse with your
computer, you may need to add commands to your MS-DOS
CONFIGSYS file. See your MS-DOS Reference Manual for
instructions.

Note
If you want to use a mouse or other pointing device
connected to a port on an option card in your computer, you
need to disable the built-in mouse connector by changing a
jumper setting in the computer. See “Changing Jumper
Settings” in Chapter 5 for instructions.
