Epson Equity 286 PLUS - Manual (Page 15)

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.
