| | | Hi Andy. The reason for symbols for AND or NAND or whatever is because those are what are used when you draw circuit diagrams. Essentially, the idea is pedagogical. Once you are familiar with them, the tradiitional AND, NAND, NOR, XOR, &c. symbols (...) (25 years ago, 24-Dec-99, to lugnet.robotics)

| | | | | | Hi, What about LEGO AND-OR matrices, like in PALs. We could use one stub to indicate each wire crossing, and use metallic 1x1 plates to "burn" contacts. The plates would be rather large though... and the electronics complicated... :-( Just a thought (...) (25 years ago, 30-Dec-99, to lugnet.robotics)

| | | | | | 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)

|
| | | | | | Is the IR tower cable straight-through or what? Tried to use the shipping version with our new Christmas 1.5 and the fit is so tight that it pushed 6 of 9 pins back through the connector on my laptop. The lesson is to use a better cable I think.

| | | | Hi Andy. Your drawing works just fine for ONE gate. Now imagine a 135 x 44 piece of paper covered with 50 or more of the things. Folks didn't come up with the special symbols in order to make things harder. Imagine trying to do arithmetic if you (...) (25 years ago, 30-Dec-99, to lugnet.robotics)
