DRAM Single In-line Memory Modules (SIMMs)

You can reconfigure DRAM capacity by changing the DRAM SIMMs on your CPU
board.
The CHIP4e+ has one 72-pin in-line memory module (SIMM) site in which to add mem-
ory. Due to the CPU speed, DRAM access time should be 70 ns or less, and must be 60
ns to run with the fastest memory setting.
