By adding memory modules to the main system board, you can expand the computer’s memory up to 5MB. Memory modules are efficient because they eliminate the need to use one of your option slots to add memory to your system. Your computer can also access memory installed on memory modules faster than memory installed on an option card. You can add a memory card, however, if you want to expand your memory up to 16MB.

You may also want to install an 80287 math coprocessor in your computer to speed up mathematical calculations in certain application programs. Check with your authorized Epson dealer to see which options are available.

Operating Systems and Other Software

You probably have a version of MS-DOS®to use with your’ Equity 286 PLUS. Epson has enhanced MS-DOS by adding two time-saving utilities-HELP and MENU-that make it easier to use. The HELP program lets you display information on the screen about any MS-DOS command. MENU provides an easy way to run many of these commands.

Note

MS-DOS is not the only operating system you can use with your computer. You can run practically any operating system compatible with MS-DOS, OS/2, Unix® or XENIX® If you use another operating system, however, 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 286 PLUS.
