(...) Well I can think of a couple reasons why we went with 4 wide tables (40.25"x40.25"). 1. It was more economical. If we were to do 3bp x 6bp you only get one table out of a 4'x8' sheet. This way you get 2 tables per sheet. 2. We liked the (...) (24 years ago, 5-Dec-00, to lugnet.general, lugnet.org.us.nelug, lugnet.trains, lugnet.loc.us.ma)

Chris If I understand correctly you can add a series resister to each reed switch using the formula r=2^n*R. Where n is the number of each switch (1,2,3...) and R is some resistence value that is friendly to the RCX. This way you can add several (...)
