Note: A total of 752 memory base address settings are available. The switches are a binary representation of the decimal addresses. Switch 1 is the Least Significant Bit and switch 7 is the Most Significant Bit. The switches have the following decimal values: switch 1=8, 2=16, 3=32, 4=64, 5=128, 6=256, 7=512. Add the values of the on switches to obtain the correct memory address. (Off=1, On=0)

MISCELLANEOUS TECHNICAL NOTES

Orientation of SW1 may vary in different revisions.
