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.

 | | 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)
