You may want to install an 80387SX, 16 MHz math coprocessor in your computer to speed up mathematical calculations in certain application programs.

Check with your authorized Epson dealer for information on optional equipment.

Operating Systems and Other Software

You probably have a version of MS-DOS® to use with your computer. However, you can run any operating system compatible with MS-DOS, OS/2, UNIX® or XENIX®. If you use another operating system, refer to the documentation that came with it to install and run it on your computer.

You can use virtually any application program designed for the IBM PC, PC XT, PC AT, or compatible computers on your Equity 386SX/16 PLUS.

VGA Utilities

Epson has included special VGA device drivers and utilities that you can use with your built-in VGA adapter. With these utilities, you can take advantage of extended VGA features such as 16-color graphics mode resolutions up to 800 x 600 and 132-column text mode. The VGA device drivers and utilities are described in the VGA Utilities booklet that came with your system.
