Note: A total of 112 memory address settings are available. The switches are a binary representation of the decimal memory addresses. SW2/1 is the Most Significant Bit and switch SW2/7 is the Least Significant Bit. The switches have the following decimal values: SW2/1=8192, SW2/2=4096, SW2/3=2048, SW2/4=1024, SW2/5=512, SW2/6=256, SW2/7=128. Turn off the switches and add the values of the switches that are off obtain the correct starting memory address. (Off=1, On=0) If SW2 is set to Disabled, SW1 should also be set to Disabled.

MISCELLANEOUS TECHNICAL NOTE

The board may be configured for any combination of conventional, expanded, and extended memory. When conventional memory is enabled, be sure to subtract 128KB from the remaining memory. When configured for both extended and expanded memory, be sure that the amount of extended memory is a multiple of 4MB.
