Epson Equity LT-386SX User Manual page 15

The 80386SX microprocessor inside your Equity LT-386SX can
run at an execution speed of 16 MHz or 8 MHz. Ordinarily,
you'll want to use the 16 MHz speed to get faster performance
from your computer. A few application programs may require
8 MHz, and the 8 MHz speed consumes less energy, if you want
to conserve battery life.
You can establish the default execution speed in the SETUP
program, which you can run when you turn on or reset the
computer. During operation, you can change the execution
speed by holding down the Ctrl key and pressing the left Shift
and F keys simultaneously.
The Equity LT-386SX h as a built-in socket for an 80387SX
math coprocessor. This socket is easily accessible from the
bottom of the computer, so you can install the chip yourself.
Or, if you prefer, have an authorized Epson dealer or Customer
Care Center install the coprocessor for you.
The built-in serial and parallel interfaces allow you to attach
almost any peripheral device, such as an Epson printer or
external modem, to your Equity LT-386SX.
You can connect a VGA color monitor to the computer to take
advantage of the color and larger display. When you insert a
connector into the port labeled RGB VIDEO before turning on
the Equity LT-386SX, the computer automatically recognizes
the presence of an external monitor. The LT-386SX supports
VGA video monochrome and color modes.
You can also connect an Epson external 5 '/+inch diskette drive
to the computer to exchange data easily with other computers
that use 5 '/+inch diskette drives.
