Epson 20 - Manual (Page 115)

Remember, your system already has 1MB of memory (consisting of
four 256KB SIMMs) installed in bank 0; so consider this when you
are deciding how much memory to add and in what configuration.
You can use the EEMM386 utility to improve memory management
in your Equity 386. See Chapter 5 for instructions.
Installing Option Cards
The Equity 386 has nine option slots so it can hold up to nine cards.
One slot is occupied by the card that controls the serial/parallel
interfaces and the floppy disk drive (known as the SPF card). The
video card that controls your monitor occupies another slot. If you
have a hard disk, its controller card occupies a third slot.
This leaves either six or seven slots in which you can install option
cards. You can buy option cards from authorized Epson dealers as
well as other vendors.
This section explains how to remove the computer’s cover, install an
option card, and then replace the cover.
Removing the Cover
To install an option card, you need to remove the cover from your
Equity 386. Follow these steps:
1. Turn off the computer and then any peripherals (including the
monitor) that are attached to it.
2. Disconnect the computer’s power cable from the back panel and
disconnect any peripheral cables that are connected to the
computer.
