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 construct a simple or complex control solution
to a variety of real world projects.

I am not sure if the company has a website but here are the details from the
package.

Logiblocs Ltd
PO Box 375 St Albans
Herts
AL1 3GA England.

As a matter of interest, the blocks are labelled with the electronic symbols
for OR, AND etc.

Hope this information is of interest.

Like this:

On diagrams, you could still use the symbols.

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 are very recognizeable and easy to
read. Also, they have a nice way of accepting multiple inputs which
simply the word "AND" doesn't.

One AND or OR or whatever isn't such a big problem, but imagine a
huge piece of paper covered with AND's, NOR's, XOR's, &c. all
connected to each other with lines which sometimes just go to
indirection symbols instead of to actual components. Basically,
you can use as much visual help as you can get. Among other
advantages, the traditional symbols have an easily recognizeable
input side and an easily recognizeable output side.

  IR tower/cable
 
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. (...) (25 years ago, 27-Dec-99, to lugnet.robotics)
