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 has 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.
