CHAPTER 3: HARDWARE INSTALLATION

THE DRAM SIMMs

The on-board DRAM memory subsystem has three module mounting
sockets which are divided into "banks' of one socket each. They support
512Kx36, 1Mx36, 2Mx36, 4Mx36, and 8Mx36 DRAM SIMMs. These
banks are labeled SIMM1, SIMM2, and SIMM3. DRAM speed must be
80ns, 70ns, or 60ns. You can configure the memory of the 486MIS in a
variety of ways. The chart below shows the possible combinations.
