Upgrading the System
You can upgrade your system by adding more memory, additional internal or
external SCSI devices, and option boards.
Open the base unit, avoid electrostatic discharge, and attach an antistatic
wrist strap as described in Chapter 3, “Opening and Closing the Base Unit,”
before upgrading the system. For information about dual screen upgrades,
refer to Chapter 6, “GLZ Graphics.”
Adding Main Memory
Intergraph’s memory upgrade kit contains two Single Inline Memory
Modules (SIMMs) and a disposable antistatic wrist strap. If you obtain
memory from a source other than Intergraph, it must meet the following
specifications:
Height: no more than 1.4 inches high
Type: 72-pin, single- or double-sided, DRAM SIMMs
Specifications: 5 volt, 70 ns, fast-page mode, 36 bit
To avoid damaging the SIMMs and voiding the warranty, take the following
precautions.
♦
Do not bend, twist, drop, or otherwise handle the SIMMs carelessly.
♦
Do not expose the SIMMs to moisture or extreme temperatures.
♦
Do not remove the SIMMs from the antistatic bag until installation.
