Adding Memory Modules
The standard Equity 386SX system comes with 1MB of on-
board memory. You can add SIMMs (single inline memory
modules) to increase the amount of memory in the computer.
With added SIMMs, the total amount of memory in your
computer must be one of the following: 2MB, 4MB, 6MB, 8MB,
10MB, 12MB, or 14MB.
You install SIMMs on the SIMM card that comes with
your computer. Any SIMMs you install must have 70ns
(nanosecond) access speed or faster to operate in the
Equity 386SX. Check with your dealer to ensure that the
correct type of SIMMs are used.
There are 16 SIMM sockets on the SIMM card organized in two
banks containing eight sockets each. Each socket can contain
either one 256KB or one 1MB SIMM. The following table
shows the possible configurations for the Equity 386SX:
