Introduction
The Epson® Equity™ 386SX is a high-performance personal
computer which offers exceptional speed and versatility in a
compact design. The computer’s 80386SX microprocessor
makes all your programs run faster, even when supporting
multitasking operations.
The Equity 386SXS available in these configurations:
A single diskette drive system with a 1.44MB (megabyte)
3 diskette drive
A hard disk drive system with one 40MB or 100MB hard
disk and a 1.44MB diskette drive.
You can install an additional diskette drive or hard disk drive,
up to a maximum of three drives total.
All models of the Equity 386SX include 1MB of internal
memory, five standard option slots (four 16-bit and one 8-bit),
serial and parallel interfaces, and an auxiliary mouse connector.
You can easily upgrade your computer by installing additional
memory and adding optional devices.
Because of its industry-standard architecture, the Equity 386SX
is fully compatible with the current installed base of personal
computer hardware and software. 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 up to 14MB by
adding memory modules to a special card that comes with the
Equity 386SX. Memory modules are efficient because they
eliminate the need to use one of your option slots to add
memory to your computer. If you do choose to use a memory
card, you can increase the computer’s memory up to 16MB.
