Board of Education Rev B
If you have a Board of Education Rev B, follow the instructions for the Board of Education
Rev C throughout the text, always keeping these two points in mind:
• The Board of Education Rev B does not have a 3-positioin switch. You will have
to disconnect battery pack’s plug from the Board of Education’s power jack when
directed to set the 3-position switch to position-0. When directed to set the 3-
position switch to position-1 or 2, you will have to plug the power in.
• The Board of Education Rev B does not have a jumper setting for power. Only
use the 6 V battery pack as a power source for Board of Education Rev B Boe-
Bot projects.
Board of Education Rev A
If you have a Board of Education Rev A, follow the instructions for the BASIC Stamp
HomeWork Board throughout the text.
