The VXI-MXI-2/B can accommodate up to two 1.35 in. 72-pin DRAM
SIMMs. Table 5-1 lists the SIMMs you can use. You can use 32- or 36-bit
SIMMs because DRAM parity is not required. Because the VXI-MXI-2/B
supports only one organization at a time, all SIMMs installed must be of the
same type. Use Bank 0 first when installing the SIMMs, and use Bank 1
when you need to install a second, matching SIMM. As shown in
Table 6-1, you can install up to 64 MB. The VXI-MXI-2/B supports
DRAM speeds of 80 ns or faster.
