Never even heard the "awesome sound" of a skilled > typist using a typewriter.....clatter clatter stottle-spop....dit. I once had an office mate that would make an awesome buzzing sound as he typed. One day I noticed the sound and turned around to see what he was doing. Much to my surprise he was doing it typing with 2 fingers. Years before the place I was consulting at asked me to help out with a program to clean the print train on an IBM 1403 N1. This printer would do 1100 lines per minute. You cleaned it by removing the ribbon and putting a Velcro like paper in the printer. So I looked at the print train and found the order characters appeared on the train. Then I wrote an assembler program using data chaining to print 100 lines with one I/O command and loop. The characters were in the same order as the print train so all the magnets could fire at once. When we ran it, the printer produced a loud screeching sound, unlike the sounds it made during regular printing. The operators were pretty happy with their new toy. The only problem is it cleaned the printer too fast so the fun didn't last long enough. -- Dan Espen
