The Epson® Equity®’ 386SX/20 PLUS is a high-performance personal computer which offers exceptional speed and convenience in a compact design. It includes 2MB of internal memory, a built-in VGA (video graphics array) display adapter, built-in parallel and serial interfaces, and an IBM®PS/2™ compatible mouse port.
The built-in interfaces allow you to connect most of your peripheral devices directly to the computer, so you do not have to install option cards. If you need to install additional devices, such as a modem or networking card, you can use the four standard option slots (three 16-bit and one 8-bit) inside the computer.
Your system can support up to three internal drives: either two diskette drives and one hard disk drive, or one diskette drive and two hard disk drives.
The Equity 3865X/20 PLUS offers several other features to enhance its speed and versatility:
Memory caching. Portions of your system memory are copied to a high-speed cache buffer so your computer can access programs and data very quickly.
Shadow RAM. Your system ROM (read-only memory) and video ROM are copied into the computer’s RAM (random access memory) to further accelerate system performance.
Super VGA mode. The built-in VGA adapter and VGA drivers (included) provide graphics resolutions up to
800 x 600 in 16 colors or 640 x 480 in 256 colors on compatible VGA monitors.
