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.

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
