6600 Qwerty           Discovered 1988 Aug. 17 by A. Mrkos at Klet.
Qwerty is a popular name for the standard Roman-alphabet typewriter keyboard, based on the first six of the top row of letters. The Qwerty design was patented by Christopher Latham Sholes of Milwaukee, and the first typewriter was produced in 1874. The name was suggested by G. Schilling.
NOTE: some special characters may not display properly (any characters within {} are an attempt to place the proper accent above a character)
