A timer based display has two sets of thumbwheel switches, and other switches for reset, start and on/off. One thumbwheel switch sets the number of attendants. The other thumbwheel switch sets the average hourly wage. The display continuously shows the cost so far, when started. Send a message to the boss by ordering the special 8 digit model, with no decimal places.-- Ling, Mar 17 2004 U.S. Patent 4,445,181 http://www.freepate...ne.com/4445181.htmlSomeone patented this in the US, but I believe this patent has now expired so build away!
