3.4.5 Memory Modules (SIMMs)

The CPU/Memory board has 16 SIMM sockets, which are divided into two

banks of 8 SIMMs each, Bank 0 and Bank 1. Bank 0 and Bank 1 SIMMs occupy

alternate slot locations; Bank 0 SIMMs are in the even numbered slots, and

Bank 1 SIMMs are in odd numbered slots. See Figure3-13.
