Epson 3865X Plus - Manual (Page 13)

Introduction
The Epson® Equity™ 386SX PLUS is a high-performance
personal computer which offers exceptional speed and
convenience in a compact design. The computer’s 16 MHz
80386SX microprocessor makes all your programs run faster,
even when supporting multitasking operations.
Your system includes either 1MB or 2MB of internal memory,
a built-in VGA (video graphics array) display adapter, built-in
parallel and serial interfaces, an IBM® PS/2™ compatible mouse
port, and four standard option slots (three 16.bit and one
8-bit). These interfaces allow you to connect most of your
peripheral devices directly to the computer, so you do not have
to install option cards. You can use the option slots to install
additional devices, such as a modem.
The Equity 386SX PLUS 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.
Optional Equipment
You can easily upgrade your computer by installing additional
memory and adding optional devices. You can install just about
any optional device that is compatible with the IBM Personal
Computer, PC XT,” or PC AT.‘”
You can expand the computer’s memory by adding memory
modules to the main system board. Memory modules are
efficient because they allow fast memory access and eliminate
the need to use an option slot. If your computer came with 1MB
of memory, you can expand it up to 10MB by installing SIMMs;
on a 2MB system, you can increase the memory up to 14MB
with SIMMs. You can add a memory card, however, if you want
to expand your computer’s memory to 16MB.
