SIMM Installation

There are four SIMM sockets organized in two banks on the
main system board. You can install 36-bit, tin-plated, fast-
page mode, single or double-sided SIMMs with a capacity of
16ME or 32ME running at 70ns or 801~. Check the following
guidelines to ensure that you choose the correct type of
SIMMs and install them properly:
double-sided SIMMs that operate at an access speed of 70
or 80 nanoseconds (ns). You can install lME, 2ME, 4ME,
or SME Sons SIMMs and 16ME or 32ME 7Ons SIMMs.
Then use Bank 1 (sockets JO650 and J0651).
The table below lists some sample memory configurations.
You can install SIMMs in many different configurations than
those listed in the table.

Video Memory Installation

The computer comes with 512KE of video memory that you
can increase to 1MB by installing four video DRAM DIP
chips. The chips must be 20-pin, 256KE, fast-page mode chips
that operate at 60ns access speed. You must install one chip
in each empty video RAM socket.
The table bellow lists the video DRAM DIP chips that are
approved for use in the computer.
