Note – These SIMMs were designed for the SPARCserver 1000 system and are
not interchangeable with other types of SIMMs.
Type A 8 Mbyte SIMMs are interchangeable with Type B 8 Mbyte SIMMs. The
two 32 Mbyte SIMM types may also be interchanged. However, SIMMs of
different capacities cannot be interchanged within a group. To select the proper
SIMM socket locations, See Appendix C, "SIMMs and Jumpers."
