What microprocessor does the Equity 386/20 use?
Q1.
A. The Equity 386/20 utilizes an Intel 80386 microprocessor running at 20
megahertz. Use of this chip allows for a high powered, high speed 32 bit
machine.
What is "Shadow Ram"? What does it do and how does it work?
Q2.
A. Shadow RAM, activated through the setup program, is used to copy
information from the system ROM BIOS and the video ROM into RAM. This
provides for faster access of BIOS information by the Equity 386/20 resulting
in enhanced system performance.
What RAM chips should be used when upgrading the memory?
Q3.
A. Use the Epson 80 nSec - 9 bit SIMM module kits to expand the system
memory. Epson supplies two memory upgrade kits, a 1 megabyte kit (4-
256K SIMM modules ) and a 2 megabyte kit (2-1 MB SIMM modules). You
can expand the memory up to 16 Megabytes directly on the 32-bit memory
card. Should you need to use third party SIMM modules we recommend the
