Electrical mech. calcs?
I'd argue that a mech. calc. is a mech. calc. even if powered by electricity. It's the computation machinery that matters. So I changed the intro text to reflect this; a mech. calc. may be implemented with electricity but not by electronics. --Wernher 10:10, 4 Mar 2005 (UTC)
Article needs additional text to either include or exclude such as there were both mechanical tabulators (that could add and subtract) and mechanical calculators.188.8.131.52 (talk) 07:18, 30 January 2013 (UTC)
