Optional Equipment

You can easily upgrade your computer by installing additional memory and adding optional devices compatible with the IBM Personal Computer, PC XT,™ or PC AT.“’

By adding memory modules to the main system board, you can expand the computer’s memory up to 16MB. Memory modules are efficient because they eliminate the need to use an option slot to add memory to your system. Your computer can also access memory on modules faster than memory on an option card.

You may also want to install a math coprocessor in your computer to speed up calculations in certain application programs. You can add an Intel ® 80387 (25MHz) or a Weitek®3167 (25MHz) math coprocessor; or you can add both by installing a Weitek dual-coprocessor adapter. 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 computer. 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.
