The Equity 386 offers a shadow RAM feature which lets you speed up processing by moving the ROM BIOS and VIDEO ROM into the RAM area of memory. When the ROM data is in RAM, the computer can access information and display text and graphics on the screen faster.

Your computer comes with version 3.3 of MS-DOS®-the operating system by Microsoft@-and version 3.2 of the GW-BASIC® programming language. You’ll find reference manuals for both MS-DOS and GW-BASIC packed in the box with the computer. You probably also purchased other software; you can use virtually any application program designed for the IBM PC, PC XT, PC AT, and 386 machines on your Equity 386.

As a supplement to MS-DOS, Epson has included several time-saving utilities that make MS-DOS easier to use: HELP MENU, and XTREE®. The HELP program lets you display information on the screen about any MS-DOS command. MENU provides an easier way to run many of the most common MS-DOS commands. XTREE is a file management utility that simplifies all file and directory operations.

MS-DOS is not the only operating system you can use with your computer. If you have a hard disk, for example, you also may want to use the more powerful MS® OS/2. Among other capabilities, MS OS/2 provides multitasking, dual mode processing, and online help. With Epson’s version of MS OS/2, you can have both MS-DOS and MS OS/2 on your Equity 386; this way, you can select which operating system to load each time you turn on the computer. Ask your Epson dealer for more information. (In particular, be sure to check the amount of RAM required to run MS OS/2.)
