The first IBM printer I was trained on at IBM Basic school in Chicago in 1979 was the 1403 N1 attached to the 2821 controller. Never a fun time trying to fix hydraulic fluid leaks. There was a "chain break" mode us CE's tried to avoid. One 1403 in the printer pool had a special modification so it could print braille for a blind programmer. Later on I was trained on the 3211 impact and 3800 laser printers.
