The PortMaster uses Four 256KB 36-pin 70ns SIMMs, but you can
replace that with four 1MB or four 4MB SIMMs. All four SIMMs
must be the same size, and you must run ComOS 3.1.2 or later.
Revision B of the Communications Server Hardware Installation Guide now
includes instructions on replacing the SIMMs, but its simple - turn off
power, open the case, replace the SIMMs, close teh case, turn on
power. As always, use anti-static precautions.
