Epson EQUITY 386/33 PLUS - Manual (Page 78)

Adding Memory Modules
Your computer comes with 4MB of memory soldered directly
onto the main system board. By installing 4MB SIMMs (single
inline memory modules), you can increase the memory in your
computer up to 16MB.
Caution
It is best to have your dealer install memory modules for
you because they can be damaged easily if installed
incorrectly. If you prefer, you can install them yourself by
carefully following the instructions in this section. However,
you could transmit an electrostatic discharge and damage
your components; so read this entire section before you
begin.
Before you install SIMMs, check the following guidelines to
ensure that they will work properly:
Use only 4MB fast page mode SIMMs that operate at an
access speed of 80ns (nanoseconds) or faster. Be sure all the
SIMMs operate at the same speed.
The Equity 386/33 PLUS can use any 4MB SIMM that
complies with industry standards; however, you should
use Epson SIMM option kits to ensure reliability and
compatibility.
