My first usable wordprocessing printer was a surplus GE Terminet 1200 which replaced a Teletype I had been using for some time. The Terminet was a "band printer" (similar to a train printer) which features a horizontal band with all printable characters moving across the line at high speed, and a hammer per character position that hits when the character to be printed appears at that position. The printing speed (and the noise) varies depending on what you are trying to print. It was quite fast for those days. And while it was less noisy than the teletype, it was still preferred to get some coffee downstairs during printing :-)

So long as you don't make much trouble the police don't really hassle anyone at all regardless of race. Unlike Boston with a billion dollar police budget and police all over the place hassling everything that moves and shutting everything down promptly at 1 AM.
