I meant on the bricks. Put the word "AND" or "NAND" or "OR".
Like this:

| The use of blocks with logic, comparison and input/output functions is part of a kit from the UK called LOGIBLOCS. The small plastic blocks have an internal circuit board that has inputs around the edges and one output connection. It is very easy to (...) (25 years ago, 26-Dec-99, to lugnet.robotics)
