[QUOTE=ngarjuna;951581]Apocryphal (I think Bill Porter said this but I don't recall it was a number of years ago): bus is actually the correct spelling, as in
busbar, but engineers in the classic days wanted to separate the spelling from confusion with the word "bus" and all of its various connotations so they took to mispelling it with the extra "s". No idea if that's true or not.

Ahhh ... Mr Bill Porter [my mentor]. A True Engineer, and a beautiful person.
and we spelled it 'Buss' ... as in 'Bussing'.
